Maintenance Window Management

# User Story: Maintenance Window Management

## Story Overview

**As a** DevOps Engineer, SRE, Release Manager, or Migration Specialist  
**I want to** schedule and manage maintenance windows in Dynatrace Managed environments through natural language interactions with the MCP server  
**So that** I can reduce alert fatigue during planned deployments, migrations, and infrastructure changes—while maintaining precise audit trails and coordinating activities across multiple Managed environments

---

## 🔍 Scope & Architecture

### What This MCP Server Does
This is a **Dynatrace Managed MCP Server**. It:
- ✅ Connects to one or more **Dynatrace Managed** environments
- ✅ Creates, modifies, and deletes maintenance windows in **Managed clusters** only
- ✅ Returns maintenance window data and schedules to the NLM (Natural Language Model)
- ✅ Supports cross-Managed-environment operations (e.g., same window on multiple Managed clusters)

### What This MCP Server Does NOT Do
- ❌ Connect to Dynatrace SaaS environments directly
- ❌ Communicate with SaaS MCP Server directly
- ❌ Create, modify, or query maintenance windows in SaaS environments

### Multi-Environment Operations
**Within Managed (supported):**
- User can create the same maintenance window across multiple Managed clusters
- NLM calls this MCP once for each target Managed environment
- Example: "Create maintenance window on managed-prod-us, managed-prod-eu, and managed-staging"

**Across Managed and SaaS (NLM-orchestrated):**
When coordination between Managed and SaaS is needed:
1. **User** makes request to **NLM** (e.g., "Create maintenance window during migration affecting both environments")
2. **NLM** calls **this Managed MCP** for Managed environment maintenance windows
3. **NLM** calls **separate SaaS MCP** for SaaS environment maintenance windows (if available)
4. **NLM** coordinates timing and scope across environments
5. **NLM** aggregates results and presents unified confirmation to user

This user story describes the **complete end-to-end workflow** to show business value, but this MCP Server only implements maintenance window management in **Dynatrace Managed environments**.

## User Value Proposition

### 1. Rapid Response During Emergencies
- **Instant ad-hoc maintenance windows** - "Create a maintenance window NOW for the next 2 hours" when unplanned deployments happen
- **Emergency deployment coverage** - quickly suppress noise when critical hotfixes require immediate deployment
- **Forgotten window recovery** - retroactively create windows when admins forgot to schedule them before deployment
- **Natural language speed** - create windows in seconds vs. minutes through UI navigation

### 2. Reduce Alert Fatigue
- **Deployment noise elimination** - suppress expected availability and performance problems during releases
- **Targeted suppression** - scope windows precisely to affected services, hosts, or clusters using tags and management zones
- **Recurring window patterns** - set up weekly deployment windows once, never manually create them again
- **Multi-environment consistency** - apply the same schedule across dev/staging/production Managed clusters

### 3. Dynamic Adjustments
- **Extend running windows** - "The deployment is taking longer, extend the window by 30 minutes"
- **Early closure** - "Deployment finished early, close the maintenance window now"
- **Scope refinement** - adjust which entities are covered mid-window if needed
- **Schedule modifications** - change recurring patterns without recreating windows

### 4. Managed-to-SaaS Migration Support
- **Wave-based scoping** - create precise windows for each migration wave (app by app, host by host, cluster by cluster)
- **Tag-based targeting** - scope windows using DQL/tags like `migration:wave1`, `environment:production`, `cluster:k8s-prod`
- **Management zone isolation** - suppress alerts only for migrating entities, not entire environments
- **Correlation with migration events** - link maintenance windows to migration events for complete audit trail

### 5. Intelligent Suggestions
- **NLM-driven recommendations** - AI suggests maintenance windows based on detected deployment patterns
- **Optimal window sizing** - recommend duration based on historical deployment times
- **Smart recurrence patterns** - detect weekly deployment schedules and suggest recurring windows
- **Conflict detection** - warn if overlapping windows or critical monitoring gaps

### 6. Integration with Fleet Updates
- **OneAgent/ActiveGate update coordination** - suggest maintenance windows during fleet update operations
- **Cluster upgrade protection** - suppress expected problems during Dynatrace platform upgrades
- **Phased rollout support** - create staggered windows for host group updates
- **Integration point for future fleet management story**

## Acceptance Criteria

### Core Capabilities

#### 1. Create Scheduled Maintenance Windows
**Given** a user plans a deployment or migration  
**When** they describe the maintenance window requirements in natural language  
**Then** the MCP server should:
- Parse the intent to extract:
  - Start date/time (or "now" for immediate)
  - Duration or end date/time
  - Recurrence pattern (one-time, daily, weekly, monthly, custom)
  - Scope (entities, tags, management zones, DQL selector)
  - Description/reason
- Use Dynatrace Settings 2.0 API with `builtin:alerting.maintenance-window` schema to create the window
- Support all scope types:
  - Management zone
  - Tag-based filtering
  - Entity selector (DQL)
  - Combination of filters
- Return confirmation with window ID, scope summary, and schedule details

**Example interactions:**
```
User: "Create a maintenance window every Tuesday from 2 PM to 4 PM UTC 
       for all services tagged deployment:weekly in Production"

MCP: Creating recurring maintenance window...
     
     Schedule:
     ✓ Recurrence: Weekly on Tuesdays
     ✓ Time: 14:00-16:00 UTC (2 hours)
     ✓ Effective from: 2026-02-04 (next Tuesday)
     
     Scope:
     ✓ Management Zone: Production
     ✓ Tag filter: deployment:weekly
     ✓ Matched entities: 12 services
       - Payment Service (SERVICE-ABC123)
       - User Service (SERVICE-ABC124)
       - Checkout Service (SERVICE-ABC125)
       ... (9 more)
     
     Suppression:
     ✓ All problems suppressed during window
     ✓ Notifications paused
     ✓ Alerting profiles: All
     
     Maintenance window created: mw-weekly-deploy-001
     Next occurrence: 2026-02-06 14:00 UTC (in 2 days)
```

#### 2. Create Ad-Hoc Maintenance Windows
**Given** an unplanned deployment or emergency change is happening  
**When** a user requests an immediate maintenance window  
**Then** the MCP server should:
- Support "now" or "immediately" as start time
- Default to 2-hour duration if not specified (prompt for confirmation)
- Allow quick scope specification (service name, host name, cluster name)
- Create window within seconds
- Confirm what entities are covered

**Example interaction:**
```
User: "Emergency hotfix deployment on Payment Service starting NOW. 
       Create a maintenance window for the next 90 minutes."

MCP: Creating emergency maintenance window...
     
     ⚠️  IMMEDIATE WINDOW - Starting now
     
     Schedule:
     ✓ Start: 2026-02-04 14:42 UTC (immediately)
     ✓ End: 2026-02-04 16:12 UTC (90 minutes)
     ✓ Type: One-time (ad-hoc)
     
     Scope:
     ✓ Service: Payment Service (SERVICE-ABC123)
     ✓ Included process groups: 3
     ✓ Included hosts: 5
     
     Reason: Emergency hotfix deployment
     
     Maintenance window ACTIVE: mw-emergency-payment-001
     Alert suppression in effect.
     
     Reminder: Window ends at 16:12 UTC (set a timer?)
```

#### 3. Create Migration-Wave Maintenance Windows
**Given** a Managed-to-SaaS migration is happening in waves  
**When** a user describes the migration wave scope  
**Then** the MCP server should:
- Support DQL-based entity selection for precise targeting
- Use tags to identify migration wave entities
- Optionally link to migration events for correlation
- Create appropriately sized windows for migration activities
- Support overlapping waves (different entities)

**Example interaction:**
```
User: "We're migrating the Payment application (wave 1) to SaaS this Saturday 
       from 8 AM to 2 PM UTC. Create a maintenance window for all entities 
       tagged migration:wave1 and app:payment"

MCP: Creating migration maintenance window...
     
     Migration Wave: Wave 1 - Payment Application
     
     Schedule:
     ✓ Date: Saturday 2026-02-08
     ✓ Time: 08:00-14:00 UTC (6 hours)
     ✓ Type: One-time (migration event)
     
     Scope Analysis:
     ✓ Tag filters: migration:wave1 AND app:payment
     ✓ Matched entities: 23 total
       - 4 services (Payment API, Payment Worker, Payment DB, Payment Cache)
       - 12 process groups
       - 7 hosts
     
     Expected Impact:
     ⚠️  Availability problems suppressed (hosts leaving Managed)
     ⚠️  Connection loss alerts suppressed
     ✓ Other production services NOT affected
     
     Maintenance window created: mw-migration-wave1-payment
     
     Would you like me to create a migration event linked to this window?

User: "Yes, create the migration event."

MCP: ✓ Migration event created: evt-migration-wave1-payment
     ✓ Event linked to maintenance window
     ✓ Both Managed environment records updated
     
     Migration tracking complete. Alert suppression ready for Saturday.
```

#### 4. Create Recurring Maintenance Windows
**Given** deployments happen on a regular schedule  
**When** a user describes the recurring pattern  
**Then** the MCP server should:
- Support recurrence patterns:
  - Daily (every day at X time)
  - Weekly (specific days of week)
  - Monthly (specific day of month or "first Monday", etc.)
  - Custom cron-like patterns if supported by Dynatrace
- Prefer creating ONE recurring window vs. multiple one-time windows
- Allow specifying end date for recurrence (or infinite)
- Show preview of next 3-5 occurrences

**Example interaction:**
```
User: "Our deployment window is every Tuesday and Thursday from 6 PM to 8 PM 
       for the next 3 months. Scope: all services in Production management zone."

MCP: Creating recurring maintenance window...
     
     Recurrence Pattern:
     ✓ Days: Tuesday, Thursday
     ✓ Time: 18:00-20:00 local time (2 hours)
     ✓ Duration: 3 months (until 2026-05-04)
     ✓ Total occurrences: ~26 windows
     
     Scope:
     ✓ Management Zone: Production
     ✓ All services (42 services currently)
     
     Next 5 occurrences:
     1. Tue 2026-02-06 18:00-20:00 UTC
     2. Thu 2026-02-08 18:00-20:00 UTC
     3. Tue 2026-02-13 18:00-20:00 UTC
     4. Thu 2026-02-15 18:00-20:00 UTC
     5. Tue 2026-02-20 18:00-20:00 UTC
     
     Maintenance window created: mw-recurring-deploy-prod
     Recurrence active until 2026-05-04.
```

#### 5. List and Query Maintenance Windows
**Given** a user wants to see scheduled or active maintenance windows  
**When** they query maintenance windows  
**Then** the MCP server should:
- List windows filtered by:
  - Status (upcoming, active, completed)
  - Time range
  - Scope (management zone, tags, entities)
  - Environment
- Show window details:
  - Schedule (start, end, recurrence)
  - Scope (entities covered)
  - Status (scheduled, active, ended)
  - Creator and creation date
- Present in human-readable format

**Example interaction:**
```
User: "What maintenance windows are scheduled for this week?"

MCP: Querying maintenance windows for this week (2026-02-04 to 2026-02-10)...
     
     Found 4 scheduled windows:
     
     1. ACTIVE NOW - Emergency Payment Hotfix
        ID: mw-emergency-payment-001
        End: Today 16:12 UTC (in 1h 30min)
        Scope: Payment Service (SERVICE-ABC123)
        Status: 🔴 ACTIVE - Alerts suppressed
     
     2. Weekly Deployment - Production
        ID: mw-recurring-deploy-prod
        Next: Tuesday 2026-02-06 18:00 UTC (in 2 days)
        Recurrence: Every Tue/Thu 18:00-20:00
        Scope: Production management zone (42 services)
        Status: ⏰ SCHEDULED
     
     3. Migration Wave 1 - Payment App

        Start: Saturday 2026-02-08 08:00 UTC (in 4 days)
        Duration: 6 hours (08:00-14:00)
        Scope: migration:wave1 AND app:payment (23 entities)
        Status: ⏰ SCHEDULED
     
     4. Weekly Deployment - Production
        ID: mw-recurring-deploy-prod (recurrence)
        Next: Thursday 2026-02-08 18:00 UTC (in 4 days)
        Scope: Production management zone (42 services)
        Status: ⏰ SCHEDULED
     
     Total: 1 active, 3 upcoming
```

#### 6. Extend or Shorten Active Maintenance Windows
**Given** a maintenance window is currently active  
**When** a user needs to adjust the duration  
**Then** the MCP server should:
- Support extending end time ("add 30 minutes", "extend until 5 PM")
- Support early closure ("close now", "end this window")
- Update the window via Settings 2.0 API
- Add comment explaining the change
- Confirm new end time

**Example interaction:**
```
User: "The deployment is taking longer than expected. 
       Extend the current maintenance window by 45 minutes."

MCP: Finding active maintenance window...
     
     Active window: mw-emergency-payment-001
     Current end time: 2026-02-04 16:12 UTC (in 1h 30min)
     
     Extending by 45 minutes...
     ✓ New end time: 2026-02-04 16:57 UTC (in 2h 15min)
     ✓ Comment added: "Window extended due to deployment delays"
     
     Maintenance window extended.
     Alert suppression now active until 16:57 UTC.

---

User: "Deployment finished successfully. Close the maintenance window early."

MCP: Finding active maintenance window...
     
     Active window: mw-emergency-payment-001
     Originally scheduled until: 16:57 UTC (still 1h 45min remaining)
     
     Closing window NOW...
     ✓ Window ended: 2026-02-04 15:12 UTC
     ✓ Duration: 2h 30min (planned 3h 15min, ended 45min early)
     ✓ Comment added: "Window closed early - deployment completed"
     
     Maintenance window closed.
     ✓ Alert suppression ENDED
     ✓ Normal monitoring resumed
     
     Reminder: Problems may take 1-2 minutes to reappear if still active.
```

#### 7. Update Maintenance Window Scope
**Given** a user needs to adjust which entities are covered  
**When** they modify the window scope  
**Then** the MCP server should:
- Support adding or removing entities, tags, or management zones
- Update the Settings 2.0 object
- Show before/after entity count
- Validate scope changes (prevent empty scope)
- Apply immediately if window is active

**Example interaction:**
```
User: "Add all hosts tagged cluster:analytics to the current maintenance window. 
       We're doing unplanned maintenance on them too."

MCP: Finding active maintenance window...
     
     Active window: mw-emergency-payment-001
     Current scope: Payment Service (SERVICE-ABC123)
     Current entities: 8 (1 service, 2 process groups, 5 hosts)
     
     Adding scope: cluster:analytics
     Analyzing impact...
     
     Additional entities: 12 hosts in Analytics cluster
     New total: 20 entities
     
     Updating maintenance window scope...
     ✓ Tag filter added: cluster:analytics
     ✓ Scope updated (effective immediately)
     ✓ Comment added: "Scope expanded to include Analytics cluster hosts"
     
     Maintenance window updated.
     Alert suppression now covers 20 entities (was 8).
```

#### 8. Delete Maintenance Windows
**Given** a user needs to cancel or remove a maintenance window  
**When** they request deletion  
**Then** the MCP server should:
- Support deleting upcoming windows (before they start)
- Prevent deletion of active windows (must close first, then delete)
- For recurring windows, offer to delete:
  - Just the next occurrence
  - All future occurrences
  - The entire recurrence pattern
- Confirm deletion with scope and schedule summary
- Warn if window is linked to migration events

**Example interaction:**
```
User: "Cancel the maintenance window scheduled for Saturday. 
       The migration is delayed."

MCP: Finding maintenance windows scheduled for Saturday 2026-02-08...
     
     Found: mw-migration-wave1-payment
     Schedule: Saturday 2026-02-08 08:00-14:00 UTC
     Scope: migration:wave1 AND app:payment (23 entities)
     Status: SCHEDULED (in 4 days)
     
     ⚠️  Warning: This window is linked to migration event evt-migration-wave1-payment
     
     Delete this maintenance window?

User: "Yes, delete it."

MCP: Deleting maintenance window...
     ✓ Window mw-migration-wave1-payment deleted
     ✓ No longer scheduled for Saturday
     
     Note: Migration event evt-migration-wave1-payment still exists.
          Should I also delete or update the migration event?

User: "Update the event to say migration postponed."

MCP: ✓ Migration event updated with status: postponed
     ✓ Comment added: "Migration postponed, new date TBD"
     
     Maintenance window deleted, migration event updated.
```

#### 9. Multi-Environment Maintenance Window Creation
**Given** the MCP server is connected to multiple Managed environments  
**When** a user wants to create the same maintenance window in multiple environments  
**Then** the MCP server should:
- Accept multiple environment IDs
- Create identical windows in each environment (same schedule, scope)
- Adjust entity selectors per environment if needed
- Report success/failure per environment
- Support bulk operations for consistency

**Example interaction:**
```
User: "Create a maintenance window on Tuesday 6 PM to 8 PM for Production 
       management zone in BOTH managed-prod-us and managed-prod-eu clusters."

MCP: Creating maintenance window in multiple environments...
     
     Target environments:
     - managed-prod-us (Managed US cluster)
     - managed-prod-eu (Managed EU cluster)
     
     Window configuration:
     ✓ Schedule: Tuesday 2026-02-06 18:00-20:00 UTC
     ✓ Scope: Management Zone "Production"
     
     Creating in managed-prod-us...
     ✓ Window created: mw-us-deploy-tue-001
     ✓ Scope: 42 services in Production
     
     Creating in managed-prod-eu...
     ✓ Window created: mw-eu-deploy-tue-001
     ✓ Scope: 38 services in Production
     
     Maintenance windows created in both clusters.
     Same schedule, environment-specific entity counts.
     
     Summary:
     - managed-prod-us: 42 services covered
     - managed-prod-eu: 38 services covered
     - Both active: Tuesday 18:00-20:00 UTC
```

#### 10. Intelligent Maintenance Window Suggestions
**Given** the MCP server detects deployment patterns  
**When** a user asks for recommendations  
**Then** the MCP server should:
- Analyze historical deployment events
- Detect recurring patterns (same day/time)
- Calculate average deployment duration
- Suggest appropriate window schedules
- Recommend scope based on past deployments

**Example interaction:**
```
User: "We deploy Payment Service almost every week. 
       Can you suggest a recurring maintenance window?"

MCP: Analyzing deployment history for Payment Service...
     
     Found 8 deployments in the last 60 days:
     - 6 on Tuesday between 17:00-19:00 UTC
     - 2 on Wednesday between 18:00-20:00 UTC
     
     Deployment duration analysis:
     - Average: 1h 15min
     - Max: 2h 10min
     - Min: 45min
     
     💡 RECOMMENDATION:
     
     Create recurring maintenance window:
     ✓ Day: Every Tuesday
     ✓ Time: 17:00-19:30 UTC (2.5 hours for safety margin)
     ✓ Scope: Payment Service (SERVICE-ABC123)
     
     This covers 75% of your historical deployment window.
     
     Should I create this recurring window?

User: "Yes, create it."

MCP: Creating recurring maintenance window...
     ✓ Recurrence: Every Tuesday 17:00-19:30 UTC
     ✓ Scope: Payment Service
     ✓ First occurrence: Next Tuesday 2026-02-06
     
     Maintenance window created: mw-recurring-payment-deploy
     
     Tip: If deployments shift to a different day, let me know 
          and I'll adjust the recurrence pattern.
```

#### 11. Fleet Update Coordination (Integration Point)
**Given** a fleet update (OneAgent, ActiveGate, cluster upgrade) is planned  
**When** a user schedules the fleet update  
**Then** the MCP server should:
- Detect that fleet updates often justify maintenance windows
- Suggest creating a maintenance window for the update duration
- Offer scope based on fleet update targets (all hosts, specific host groups, etc.)
- Link maintenance window to fleet update activities

**Example interaction:**
```
User: "Schedule OneAgent update for all Production hosts this Friday midnight."

MCP: OneAgent fleet update scheduled for Friday 2026-02-08 00:00 UTC.
     
     💡 Suggestion: Create a maintenance window?
     
     Fleet updates often cause:
     - Brief agent disconnections
     - Process group restarts
     - Temporary monitoring gaps
     
     Recommended maintenance window:
     ✓ Start: Friday 2026-02-08 00:00 UTC
     ✓ Duration: 3 hours (typical for ~50 hosts)
     ✓ Scope: All Production hosts
     
     This will suppress expected availability/monitoring problems during the update.
     
     Create this maintenance window?

User: "Yes."

MCP: Creating maintenance window for fleet update...
     ✓ Window: mw-fleet-oneagent-prod-001
     ✓ Schedule: Friday 00:00-03:00 UTC
     ✓ Scope: Management Zone "Production" (52 hosts)
     ✓ Linked to: OneAgent update job fleet-update-20260208
     
     Maintenance window created and linked to fleet update.
     Alert suppression will activate during update window.
```

## Technical Implementation Requirements

### MCP Tools to Implement

#### Tool 1: `create-maintenance-window`
**Purpose:** Create a new maintenance window (scheduled or ad-hoc)

**Inputs (Zod schema):**
```typescript
{
  environmentId: string | string[],    // One or more Managed environments
  name: string,                         // Display name
  description?: string,                 // Optional description/reason
  schedule: {
    startTime: string,                  // ISO timestamp or "now"
    endTime?: string,                   // ISO timestamp (or use duration)
    duration?: number,                  // Minutes (alternative to endTime)
    recurrence?: {                      // Optional: for recurring windows
      pattern: "daily" | "weekly" | "monthly" | "custom",
      daysOfWeek?: number[],            // For weekly (0=Sunday, 1=Monday, etc.)
      dayOfMonth?: number,              // For monthly
      endDate?: string,                 // When recurrence stops (optional)
      cronExpression?: string           // For custom patterns
    }
  },
  scope: {
    managementZones?: string[],         // Management zone IDs or names
    tags?: string[],                    // Tag filters (e.g., "deployment:weekly")
    entitySelector?: string,            // DQL selector
    entities?: string[]                 // Explicit entity IDs
  },
  suppressAlertingProfiles?: string[],  // Specific alerting profiles (or all)
  linkedEventId?: string,               // Optional: link to deployment/migration event
  metadata?: {                          // Optional structured metadata
    reason?: string,                    // "deployment", "migration", "maintenance", etc.
    ticket?: string,
    owner?: string
  }
}
```

**Implementation:**
- Parse natural language to extract schedule and scope
- If startTime is "now" or relative, convert to absolute timestamp
- Construct Settings 2.0 payload for `builtin:alerting.maintenance-window` schema
- For multiple environments, create window in each sequentially
- Validate scope (ensure entities exist)
- POST to `/api/v2/settings/objects` with appropriate payload
- Return created window ID(s) and confirmation

#### Tool 2: `list-maintenance-windows`
**Purpose:** Query and list maintenance windows

**Inputs:**
```typescript
{
  environmentId: string,
  filters?: {
    status?: "scheduled" | "active" | "ended" | "all",
    fromDate?: string,                  // Date range filter
    toDate?: string,
    managementZone?: string,            // Filter by scope
    tags?: string[],
    includeRecurring?: boolean          // Show all recurrence instances
  },
  includeDetails?: boolean              // Full details vs. summary
}
```

**Implementation:**
- GET `/api/v2/settings/objects?schemaIds=builtin:alerting.maintenance-window`
- Filter results based on schedule and scope
- Determine status (active, scheduled, ended) based on current time
- Format for human-readable output
- For recurring windows, calculate next occurrences

#### Tool 3: `update-maintenance-window`
**Purpose:** Modify an existing maintenance window

**Inputs:**
```typescript
{
  environmentId: string,
  windowId: string,                     // Settings object ID or friendly name
  updates: {
    extendBy?: number,                  // Minutes to extend (for active windows)
    newEndTime?: string,                // Set specific end time
    closeNow?: boolean,                 // Close window immediately
    scope?: {                           // Update scope
      add?: {                           // Add entities/tags
        managementZones?: string[],
        tags?: string[],
        entities?: string[]
      },
      remove?: {                        // Remove entities/tags
        managementZones?: string[],
        tags?: string[],
        entities?: string[]

      endTime?: string
    }
  },
  comment?: string                      // Reason for update
}
```

**Implementation:**
- Fetch existing window from Settings 2.0
- Apply updates to the settings object
- Validate changes (e.g., can't move active window to the past)
- PUT `/api/v2/settings/objects/{objectId}` with updated payload
- Add comment/audit trail
- Return updated window summary

#### Tool 4: `delete-maintenance-window`
**Purpose:** Cancel or remove a maintenance window

**Inputs:**

  force?: boolean                       // Allow deleting active window (closes first)
}
```

**Implementation:**
- Fetch window from Settings 2.0
- If active and force=false, return error (must close first)
- If active and force=true, close then delete
- For recurring windows, handle deleteType:
  - "this": Cancel only next occurrence (if supported by schema)
  - "future": Cancel all future occurrences
  - "all": Delete entire recurrence pattern
- DELETE `/api/v2/settings/objects/{objectId}`
- Return confirmation

- Parse and format for display:
  - Schedule (start, end, recurrence)
  - Scope (entities, tags, management zones)
  - Status (active, scheduled, ended)
  - Creator and timestamps
  - Linked events or metadata
- Show matched entities count
- If recurring, show next 5 occurrences

#### Tool 6: `suggest-maintenance-window`
**Purpose:** Analyze deployment history and suggest optimal windows

**Inputs:**
```typescript
{
  environmentId: string,
  entitySelector?: string,              // Scope to analyze (service, host group, etc.)

  suggestRecurring?: boolean            // Prefer recurring vs. one-time (default: true)
}
```

**Implementation:**
- Query Events API for historical deployment events
- Filter by entity selector if provided
- Analyze patterns:
  - Day of week frequency
  - Time of day clustering
  - Duration statistics (avg, max, p95)
- Detect recurring patterns
- Generate recommendation with:
  - Suggested schedule
  - Recommended duration
  - Scope
  - Confidence level
- Return suggestion for user approval

#### Tool 7: `link-window-to-event`
**Purpose:** Associate a maintenance window with a deployment/migration event

**Inputs:**
```typescript
{
  environmentId: string,
  windowId: string,
  eventId: string,                      // Event correlation ID

     Migration window ready for Saturday!
```

### Scenario 4: Deployment Taking Longer - Extend Window
```
User: "The deployment is running longer than expected. 
       Extend the current window by 1 hour."

MCP: Finding active maintenance window...
     
     Active window: mw-recurring-prod-deploy
     Current schedule: 18:00-20:00 UTC (ends in 25 minutes)
     
     Extending by 1 hour...
     ✓ New end time: 21:00 UTC (ends in 1h 25min)
     ✓ Comment added: "Extended due to deployment delays"
     ✓ Duration: 3 hours (was 2 hours)
     
     Maintenance window extended.
     Alert suppression now active until 21:00 UTC.
     
     Reminder: This is a recurring window. Extension only applies to 
               TODAY'S occurrence. Next Tuesday's window remains 2 hours.
```

### Scenario 5: Multi-Environment Consistency
```
User: "Create the same weekly deployment window in all 3 of our Managed clusters: 
       managed-us, managed-eu, and managed-apac. 
       Every Wednesday 10 PM local time, 2 hours, Production services."

MCP: Creating maintenance window across 3 Managed environments...
     
     Configuration:
     ✓ Recurrence: Weekly on Wednesdays
     ✓ Duration: 2 hours
     ✓ Scope: Management Zone "Production"
     
     Time zone handling:
     ⚠️  Note: You said "local time" but each cluster is in different timezone.
     
     Options:
     1. Use each cluster's local timezone (22:00 local)
     2. Use same UTC time (22:00 UTC = different local times)
     3. Specify exact times per cluster
     
     Which approach?

User: "Option 1 - each cluster's local time 10 PM."

MCP: Creating environment-specific windows...
     
     managed-us (UTC-5):
     ✓ Window: mw-us-wed-deploy
     ✓ Schedule: Wednesdays 03:00-05:00 UTC (22:00-00:00 local)
     ✓ Scope: 42 services in Production
     
     managed-eu (UTC+1):
     ✓ Window: mw-eu-wed-deploy
     ✓ Schedule: Wednesdays 21:00-23:00 UTC (22:00-00:00 local)
     ✓ Scope: 38 services in Production
     
     managed-apac (UTC+8):
     ✓ Window: mw-apac-wed-deploy
     ✓ Schedule: Wednesdays 14:00-16:00 UTC (22:00-00:00 local)
     ✓ Scope: 31 services in Production
     
     All 3 maintenance windows created!
     Each activates at 22:00 in its local timezone.
     
     Summary:
     - US: Wednesdays 10 PM EST (03:00 UTC)
     - EU: Wednesdays 10 PM CET (21:00 UTC)
     - APAC: Wednesdays 10 PM SGT (14:00 UTC)
```

### Scenario 6: Fleet Update with Window Suggestion
```
User: "Schedule OneAgent update for all Production hosts this Sunday at midnight."

MCP: Scheduling OneAgent fleet update...
     
     Fleet Update Configuration:
     ✓ Target: All Production hosts (52 hosts)
     ✓ Schedule: Sunday 2026-02-09 00:00 UTC
     ✓ Update version: OneAgent 1.285.0
     ✓ Rollout strategy: Host-by-host (safer, slower)
     
     Estimated duration: 2-3 hours for 52 hosts
     
     💡 RECOMMENDATION: Create maintenance window?
     
     During OneAgent updates, you may see:
     - Brief host connectivity issues
     - Process group restarts
     - Monitoring data gaps (1-2 min per host)
     - False AVAILABILITY problems
     
     Suggested maintenance window:
     ✓ Start: Sunday 00:00 UTC (same as fleet update)
     ✓ Duration: 4 hours (buffer for safety)
     ✓ Scope: All Production hosts (52 hosts)
     
     This will suppress expected problems during the update.
     Create this window?

User: "Yes, create it."

MCP: Creating coordinated maintenance window...
     
     ✓ Window: mw-fleet-oneagent-prod-20260209
     ✓ Schedule: Sunday 2026-02-09 00:00-04:00 UTC (4 hours)
     ✓ Scope: Production management zone (52 hosts)
     ✓ Linked to: Fleet update job fleet-update-oneagent-20260209
     
     Setup complete:
     ✓ Fleet update scheduled
     ✓ Maintenance window scheduled
     ✓ Both linked for tracking
     
     On Sunday at midnight:
     1. Maintenance window activates (alerts suppressed)
     2. OneAgent update begins
     3. Rollout proceeds host-by-host
     4. Window closes at 04:00 UTC (or earlier if you close manually)
     
     You'll be notified when the fleet update completes.
```

### Scenario 7: Deployment Finished Early - Close Window
```
User: "Great news, deployment finished in 45 minutes instead of 2 hours. 
       Close the maintenance window now."

MCP: Finding active maintenance window...
     
     Active window: mw-recurring-prod-deploy
     Started: 18:00 UTC (45 minutes ago)
     Scheduled end: 20:00 UTC (1h 15min remaining)
     
     Closing window early...
     ✓ Window closed: 2026-02-04 18:45 UTC
     ✓ Actual duration: 45 minutes (vs. 2 hours planned)
     ✓ Saved: 1h 15min of suppression time
     ✓ Comment added: "Window closed early - deployment completed ahead of schedule"
     
     Maintenance window CLOSED.
     
     ✓ Alert suppression ENDED
     ✓ Normal monitoring RESUMED
     ✓ Problem detection active again
     
     Note: Problems may take 1-2 minutes to re-evaluate and appear if issues exist.
     
     Deployment completed 37.5% faster than planned! 🚀
```

## Non-Functional Requirements

### Performance
- Maintenance window creation should complete within 3 seconds
- Multi-environment operations should use parallel API calls
- Window queries should return within 2 seconds
- Scope validation (entity count) should complete within 5 seconds

### Security
- All API tokens remain server-side (not exposed to users)
- Validate user has appropriate Dynatrace permissions (`settings.read`, `settings.write`)
- Audit all maintenance window operations with user identity
- Prevent unauthorized scope expansion (e.g., can't create window for management zones user doesn't own)

### Error Handling
- If entity selector matches zero entities, warn user (empty scope)
- If start time is in the past (except for retroactive emergency windows), confirm intent
- If overlapping windows exist for same scope, warn about redundancy
- Gracefully handle Settings 2.0 schema version differences between Managed versions
- If recurring pattern is invalid (e.g., "31st of every month"), suggest alternatives

### Observability
- Log all maintenance window lifecycle operations (create, update, extend, close, delete)
- Track metrics: windows created per day, average duration, extension frequency
- Monitor API latency and error rates
- Alert if window creation fails repeatedly

### Usability
- Natural language flexibility: accept "now", "tomorrow", "next Tuesday", "in 2 hours", etc.
- Support timezone-aware scheduling (UTC, local, specific timezones)
- Preview scope before creating window (show entity count)
- Confirm high-impact operations (e.g., multi-environment, long duration, broad scope)

### Audit and Compliance
- Every maintenance window operation must include:
  - User identity (who created/modified)
  - Timestamp (when)
  - Reason/description (why)
  - Environment and scope (what/where)
- Support exporting window history for compliance review
- Preserve audit trail even after window is deleted

---

## Out of Scope (Future Stories)

The following related features are **not included** in this story but are candidates for future work:

1. **Automatic Window Creation from CI/CD** - Directly trigger window creation from Jenkins/GitLab/GitHub Actions
2. **Smart Window Duration Prediction** - ML-based prediction of optimal window length based on deployment complexity
3. **Maintenance Window Templates** - Pre-defined templates for common scenarios (weekly deploy, monthly maintenance, migration waves)
4. **Window Collision Detection** - Prevent scheduling conflicting windows; suggest alternative times
5. **Notification Preferences** - Custom notification behavior during windows (suppress all vs. critical only)
6. **Window Effectiveness Metrics** - Track how many problems were suppressed, cost savings, etc.
7. **Approval Workflows** - Require approval before creating production maintenance windows
8. **Window Handoff Automation** - Automatically extend or adjust windows based on real-time deployment progress

---

## Dependencies

### Dynatrace APIs Required
- Settings 2.0 API (`/api/v2/settings/...`)
  - Schema: `builtin:alerting.maintenance-window`
  - GET `/api/v2/settings/schemas/builtin:alerting.maintenance-window` - Schema definition
  - POST `/api/v2/settings/objects` - Create window
  - PUT `/api/v2/settings/objects/{objectId}` - Update window
  - DELETE `/api/v2/settings/objects/{objectId}` - Delete window
  - GET `/api/v2/settings/objects?schemaIds=builtin:alerting.maintenance-window` - Query windows
- Entities API v2 (`/api/v2/entities`) - Validate entity selectors and count entities
- Events API v2 (`/api/v2/events/ingest`) - Link to deployment/migration events (optional)

### Existing MCP Server Capabilities
- Multi-environment connection management (already implemented)
- Authentication via API tokens (already implemented)
- NLM integration for natural language parsing
- Event ingestion (from previous user story) - for linking windows to events
- Problem lifecycle management (from previous user story) - for coordinating window closure with problem resolution

### External Integrations (Future)
- CI/CD tools (Jenkins, GitLab CI, GitHub Actions) - trigger window creation
- Fleet management system (future story) - coordinate with OneAgent/ActiveGate updates
- Calendar systems (Google Calendar, Outlook) - sync maintenance windows to team calendars

---

## Success Metrics

### Efficiency Gains
- **Target:** Reduce maintenance window creation time by 80% compared to manual UI workflow
- **Measure:** Time from user request to active window (avg. <10 seconds via MCP vs. 2-3 minutes in UI)

### Alert Fatigue Reduction
- **Target:** 70% reduction in unnecessary alerts during deployments
- **Measure:** Compare problem notification count during windowed vs. non-windowed deployments

### Migration Support
- **Target:** 95% of migration waves use maintenance windows
- **Measure:** Track migration events with linked maintenance windows

### User Adoption
- **Target:** 80% of users create at least one maintenance window via MCP within first month
- **Measure:** Track `create-maintenance-window` tool usage

### Recurring Window Efficiency
- **Target:** 60% of maintenance windows are recurring (not one-time)
- **Measure:** Track recurring vs. one-time window creation ratio

### Multi-Environment Consistency
- **Target:** 50% of windows are created across multiple Managed clusters simultaneously
- **Measure:** Track multi-environment window creation

---

## Testing Strategy

### Unit Tests
- Validate Settings 2.0 payload construction for maintenance windows
- Test natural language parsing for schedules (relative and absolute times)
- Verify entity selector construction from tags and management zones
- Test recurrence pattern generation (daily, weekly, monthly)
- Validate scope validation logic (entity count, empty scope detection)

### Integration Tests
- E2E: Create scheduled window, verify in Dynatrace, let it activate, verify suppression
- E2E: Create ad-hoc window immediately, verify it's active within seconds
- E2E: Extend active window, verify new end time
- E2E: Close window early, verify suppression ends
- E2E: Create recurring window, verify next occurrences calculated correctly
- Cross-environment: Create same window in multiple Managed clusters

### Contract Tests
- Validate against latest `builtin:alerting.maintenance-window` schema from Managed
- Test with different schema versions (ensure backward compatibility)
- Verify all required fields are included
- Test optional field combinations

### User Acceptance Tests
- Scenario: DevOps engineer creates weekly deployment window
- Scenario: SRE creates emergency window during unplanned outage
- Scenario: Migration specialist creates wave-based migration windows
- Scenario: Platform engineer extends window mid-deployment
- Scenario: Team lead queries upcoming windows across environments

### Load Tests
- Create 100+ windows across multiple environments
- Verify performance remains acceptable (< 5 seconds per operation)
- Test parallel window creation (multiple users simultaneously)

## Risks and Mitigations

| Risk | Impact | Mitigation |
|------|--------|-----------|
| Incorrect scope suppresses too many alerts | High - could hide critical production issues | Always preview entity count before creation; require confirmation for broad scope (>50 entities) |
| Maintenance window forgotten/not closed | Medium - extended suppression hides real problems | Send reminders when window approaches end time; auto-close option after deployment events |
| Timezone confusion causes wrong timing | High - window activates at wrong time | Always confirm timezone; show time in UTC AND local time; support explicit timezone specification |
| Recurring pattern miscalculation | Medium - windows at wrong times | Show preview of next 3-5 occurrences; allow user to verify before creation |
| Schema version differences across Managed clusters | Medium - window creation may fail on older clusters | Detect Managed version; adjust payload to compatible schema version; warn about unsupported features |
| Overlapping windows create confusion | Low - redundant suppression | Detect overlaps; warn user; suggest consolidating windows |
| Retroactive windows don't suppress existing problems | Low - expectations mismatch | Clearly communicate that retroactive windows prevent NEW alerts, don't clear existing problems |

Schema version differences across Managed clusters	Medium - window creation may fail on older clusters	Detect Managed version; adjust payload to compatible schema version; warn about unsupported features
Overlapping windows create confusion	Low - redundant suppression	Detect overlaps; warn user; suggest consolidating windows
Retroactive windows don't suppress existing problems	Low - expectations mismatch	Clearly communicate that retroactive windows prevent NEW alerts, don't clear existing problems
