Add Istio annotation to kagenti-ui pod to exclude K8s API server (10.96.0.1/32)
from sidecar traffic interception. This fixes connection reset errors when
the UI attempts to query namespaces and configmaps via the Kubernetes API.
Fixes error:
urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='10.96.0.1', port=443):
Max retries exceeded with url: /api/v1/namespaces?labelSelector=kagenti-enabled%3Dtrue

to query namespaces and configmaps via the Kubernetes API.
Changes:
- Created istio-exclude-patch.yaml for strategic merge patching
- Updated kustomization.yaml to apply the patch
- Reverted direct annotation in deployment.yaml (now handled by patch)

Add PERMISSIVE mTLS policies for services accessed via OAuth2-Proxy: - Phoenix (port 6006) - Tempo (port 3100) - Kiali (port 20001) Root cause: OAuth2-Proxy connects to backend services using plain HTTP, but STRICT mTLS policies force Istio sidecars to use mTLS, resulting in TLS version mismatch errors. Solution: Configure port-level PERMISSIVE mTLS for OAuth2-Proxy upstreams while maintaining STRICT mTLS for all other traffic.

Restart operator pod 2. Delete/recreate webhook configuration 3. Regenerate certificate via cert-manager ## Diagnostic Evidence: - Certificate SANs: kagenti-operator-webhook-service.kagenti-system.svc + FQDN - Webhook caBundle: Correctly injected, matches certificate - Cert-manager annotation: Present and correct - Secret mount: Configured correctly in deployment ## Possible Root Causes: 1. Operator webhook server not presenting certificate correctly 2. Kubernetes API server webhook validation bug 3. Cert-manager integration issue 4. Cached invalid state in operator ## Impact on Phase 0.5: **BLOCKED TASKS**: - Test agent import script - E2E agent testing locally - E2E agent testing in CI **CAN PROCEED**: - Documentation tasks (not blocked) - Script creation (already complete) ## Workarounds: 1. **Temporary**: Disable webhook validation (DANGEROUS) 2. **Alternative**: Use static agent manifests instead of AgentBuild ## Next Steps: - Report to kagenti-operator maintainers - Full platform redeployment test - Compare with working webhooks (tekton, istio) - Review operator webhook server source code 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

…oki dashboard
Dashboard Enhancements:
=======================
Added 3 new panels to Loki Logs Explorer dashboard:
1. **Error Cumulative Counts by Namespace** (timeseries)
- Stacked area chart showing error log accumulation by namespace
- Helps identify which namespaces generate most errors over time
- Uses LogQL: sum by (namespace) (count_over_time({...} |~ "(?i)(error|ERROR)" [...]))
2. **Warning Cumulative Counts by Namespace** (timeseries)
- Stacked area chart showing warning log accumulation by namespace
- Parallel to error chart for comprehensive log level analysis
- Uses LogQL: sum by (namespace) (count_over_time({...} |~ "(?i)(warn|WARNING)" [...]))
3. **Log Errors vs Alerts (Coverage Analysis)** (timeseries)
- Correlation chart showing gap between error logs and firing alerts
- Dual Y-axis: Error log rate (Loki) + Firing alerts count (Prometheus)
- Helps identify missing alerting rules (high errors, low alerts)
- Uses both Loki and Prometheus datasources
Visual Features:
- Cumulative charts use stacked area with smooth interpolation
- Legend shows sum and last values for trend analysis
- Correlation chart uses dual Y-axis with color coding
- Charts positioned after stats, before log volume section
Test Coverage:
==============
Added 17 pytest tests in test_grafana_loki_dashboard.py:
✅ Dashboard structure validation (4 tests)
- File exists and valid JSON
- Has new panels (error/warning cumulative, correlation)
- Dashboard version updated to 3
- Panel count is 14 (11 original + 3 new)
✅ Panel type validation (14 parametrized tests)
- Stats for counts
- Timeseries for trends
- Logs for raw log views
- Tables for top sources
Total test coverage: 17 test cases
Use Case:
=========
These charts enable platform operators to:
1. Track error/warning trends by namespace over time
2. Identify noisy namespaces that need investigation
3. Detect alerting gaps (errors not covered by alerts)
4. Validate alert coverage and tune alert thresholds

PROBLEM: - Korrel8r was disabled due to CrashLoopBackOff with :latest image - Missing true log↔alert correlation (currently using simple comparison) - Need Korrel8r API for "logs without alerts" queries SOLUTION: - Use stable version 0.7.6 (December 2024) instead of :latest - Latest version (0.8.4, October 2025) has Go runtime issues - Re-enable in kustomization.yaml Available versions found via Quay.io API: - latest: Oct 29, 2025 (has issues) - 0.8.4: Oct 29, 2025 - 0.8.3: Oct 21, 2025 - 0.8.2: Sep 10, 2025 - 0.7.7: Feb 13, 2025 - 0.7.6: Dec 19, 2024 ← USING THIS (stable) - 0.7.5: Nov 23, 2024 - 0.7.4: Nov 12, 2024 Changes: - components/02-observability/korrel8r/deployment.yaml: Image changed from :latest to :0.7.6 - components/02-observability/kustomization.yaml: Uncommented korrel8r/ resource Next Steps (after deployment): 1. Test Korrel8r API: http://korrel8r.observability.svc:8080/api/v1alpha1/graphs 2. Query for uncorrelated logs via neighbors API 3. Add Grafana datasource for Korrel8r (if supported) 4. Update "Log Errors vs Alerts" chart to use Korrel8r correlation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
…anic - Tested versions: latest (Oct 2025), 0.8.4, 0.7.6 (Dec 2024 'stable') - All exhibit same CrashLoopBackOff with Go garbage collector panic - Documented Quay.io API findings and version analysis - Updated workaround strategy (Grafana native correlation) - Noted dashboard correlation limitation (simple comparison vs true graph-based) - Added references to correlation chart in loki-logs.json (panel 14) - Conclusion: Upstream bug in ALL container image builds - requires vendor fix
- Attempted to use stable version 0.7.6 (Dec 2024) instead of :latest - Result: Same CrashLoopBackOff with Go runtime panic - Tested versions: latest, 0.8.4, 0.7.6 - ALL fail identically - Updated kustomization.yaml comment to reflect investigation results - Comprehensive findings documented in TODO_TRACING.md Issue 1 - Conclusion: Upstream container image bug affecting all releases
- Deploy Korrel8r Operator v0.1.7 as alternative to direct deployment - Uses official GitHub config/default kustomization - Sync wave 15 (infrastructure layer, same as OTEL operator) - Namespace: korrel8r (operator creates/manages Korrel8r instances) - Automatic prune and self-heal enabled - Operator manages CRDs, RBAC, and controller deployment - Image: quay.io/korrel8r/operator:0.1.7 - Next: Create Korrel8r CR for operator to manage correlation service
Investigation Results: - Tested Korrel8r Operator v0.1.7 as alternative deployment method - Operator controller-manager crashes with identical Go GC worker panic - Error: runtime.gcBgMarkWorker() goroutine failure (same as service) - Image: quay.io/korrel8r/operator:0.1.7 Root Cause: - Upstream Go runtime/compiler bug affects ENTIRE Korrel8r project - Both service containers (korrel8r:*) AND operator containers fail - All versions tested exhibit same failure (0.6.4 - latest) Impact: - Direct Korrel8r deployment: BLOCKED - Operator-based Korrel8r deployment: BLOCKED - No working deployment method available Workaround: - Grafana native correlation (trace↔log via derivedFields) - Dashboard correlation chart (simple comparison vs true graph-based) Documented in TODO_TRACING.md Issue 1 (updated 2025-11-18)
Fixes CI failure where istio-proxy sidecar crashes during Ollama pod startup.
## Problem
- Ollama deployment was getting Istio sidecar injected (kagenti-system namespace has Istio enabled)
- Istio sidecar startup probe failed during slow Ollama image pull (~2+ minutes)
- CI showed: `istio-proxy: CrashLoopBackOff` - NOT an Ollama crash!
- Error: `Startup probe failed: dial tcp 10.244.0.43:15021: connect: connection refused`
## Root Cause
- Missing `sidecar.istio.io/inject: "false"` annotation on Ollama pod template
- Ollama is a platform service that doesn't need mTLS (uses HTTP internally)
- Large ollama/ollama:latest image pull delays pod readiness
- Istio sidecar expects main container to be ready quickly
## Solution
Added annotation to disable Istio sidecar injection:
```yaml
template:
metadata:
annotations:
sidecar.istio.io/inject: "false"
```
## Testing
- Local deployment: Ollama runs successfully without sidecar
- CI: Should now start without istio-proxy crashes

Replaces obsolete file-based method with kubectl secret query.
## Changes
- **quick-redeploy.sh**: Updated "Get ArgoCD admin password" instruction
- Old: `cat /tmp/argocd-pass.txt` (file no longer created)
- New: `kubectl get secret -n argocd argocd-initial-admin-secret -o jsonpath='{.data.password}' | base64 -d`
## Reason
The `/tmp/argocd-pass.txt` file is no longer created during ArgoCD installation.
ArgoCD now stores the initial admin password in a Kubernetes secret.

Add target_config.sync_period to Promtail ConfigMap to periodically re-sync log file targets. This allows Promtail to close file handles to terminated pods and prevents file descriptor exhaustion. Also add health probes to DaemonSet for better restart behavior. Fixes: - CrashLoopBackOff with 'failed to make file target manager: too many open files' - Observability app stuck in Progressing state Changes: - promtail-configmap.yaml: Add target_config.sync_period=30s - promtail-daemonset.yaml: Add liveness and readiness probes 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Reduces file descriptor pressure and adds observability for Promtail. ## Changes **Promtail Configuration:** - Add `target_config.sync_period: 30s` (from default 10s) - Reduces directory rescan frequency to minimize file descriptor churn - Correctly placed at root level (not in scrape_configs) **Grafana Alert:** - Add `promtail-high-file-descriptors` alert - Triggers when `promtail_files_active_total > 5000` - Provides early warning before "too many open files" errors - 10-minute evaluation period to avoid false positives ## Why Promtail can hit "too many open files" errors in environments with: - Many pods/namespaces - High log rotation rates - Limited file descriptor quotas ## Testing Monitor the metric in Grafana: ```promql promtail_files_active_total ``` Alert will fire if file count exceeds 5000 for 10+ minutes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Migrated from Promtail to Grafana Alloy as the unified telemetry collector for log, metric, and trace collection. Promtail is deprecated and Alloy provides superior functionality. ## Changes ### New Alloy Components - **alloy-configmap.yaml**: Component-based Alloy configuration - Kubernetes pod discovery and log collection - OTLP receivers (gRPC port 4317, HTTP port 4318) - Loki integration for log forwarding - Tempo integration for distributed tracing - Prometheus integration for metrics - Process logs with JSON field extraction - **alloy-daemonset.yaml**: DaemonSet deployment (one pod per node) - Runs as non-root user (65534) - Collects logs via Kubernetes API (not file-based) - No "too many open files" issues (vs Promtail) - Includes OTLP endpoints for applications - **alloy-service.yaml**: Service exposing OTLP endpoints - Port 4317: OTLP gRPC - Port 4318: OTLP HTTP - Port 12345: Alloy HTTP server (metrics, health) - **alloy-rbac.yaml**: ServiceAccount + RBAC for Kubernetes API access - Read pods, services, endpoints, namespaces, nodes - Read pod logs via Kubernetes API ### Removed Promtail Components - Removed promtail-rbac.yaml - Removed promtail-configmap.yaml - Removed promtail-daemonset.yaml (Note: Old files remain in Git history) ### Updated Grafana Alerts - Replaced `promtail-pods-down` with `alloy-pods-down` - Removed `promtail-high-file-descriptors` (not applicable to Alloy) - Updated component labels: promtail → alloy ### Updated Kustomization - Updated resource references to use Alloy manifests - Added alloy-service.yaml to resources - Updated description to mention Alloy ## Benefits 1. **Modern architecture**: Alloy is the future of Grafana telemetry 2. **Unified collection**: Logs + Metrics + Traces in one collector 3. **OTLP support**: Native OpenTelemetry Protocol receivers 4. **Better performance**: Kubernetes API-based log collection 5. **No file descriptor issues**: No file watching, no "too many open files" 6. **Non-root security**: Runs as non-privileged user 7. **Component-based config**: More maintainable than YAML ## Migration Notes - Applications can now send OTLP data directly to Alloy: - gRPC: `alloy.observability.svc:4317` - HTTP: `alloy.observability.svc:4318` - Logs still flow to Loki as before - No changes required to Loki configuration - Metrics can be sent to Prometheus via Alloy - Traces can be sent to Tempo via Alloy ## Reference - https://grafana.com/docs/alloy/latest/set-up/migrate/from-promtail/ - https://grafana.com/docs/alloy/latest/ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Resolves read-only filesystem error preventing Alloy from starting. ## Problem Alloy pods failing with CrashLoopBackOff: - Error: "mkdir data-alloy: read-only file system" - Root cause: readOnlyRootFilesystem=true without writable data volume - Alloy's remotecfg service requires /data-alloy directory ## Solution Added emptyDir volume mount for Alloy data directory: - Mount path: /data-alloy - Volume type: emptyDir (ephemeral, node-local storage) - Maintains security: readOnlyRootFilesystem still true for main filesystem ## Changes - Added "data" volume mount to alloy container (line 98-99) - Added "data" emptyDir volume definition (line 139-140) ## Testing Local cluster: Alloy pods should now start successfully CI: Will validate in next run 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Problem: Alloy failing to start with error:
unrecognized block name "backoff_config" at line 153
Root cause: backoff_config block syntax is deprecated in Alloy v1.5.1.
The old Promtail-style nested block is no longer supported.
Fix: Updated loki.write endpoint configuration to use new syntax:
- backoff_config { ... } → flat parameters
- Added retry_on_http_429 = true
- Renamed: min_period → min_backoff_period
- Renamed: max_period → max_backoff_period
- Renamed: max_retries → max_backoff_retries
This aligns with Alloy v1.5.1 documentation for loki.write endpoint
retry configuration.
