# Render automated dashboards
2+
3+
[Render](https://render.com/) is a cloud platform-as-a-service for running web services, background workers, persistent disks, Postgres databases and Key Value (Valkey/Redis) instances.
4+
5+
These dashboards display data emitted by Render's [OpenTelemetry metrics stream](https://render.com/docs/metrics-streams), forwarded to AppSignal through the AppSignal collector. The collector's Render router converts CPU, memory, disk usage, disk I/O and network I/O metrics into host metrics; the remaining `render.*` metrics are exposed as custom metrics and power these dashboards.
6+
7+
The following automated dashboards may appear:
8+
9+
- [HTTP automated dashboard](#http-automated-dashboard)
10+
- [Postgres automated dashboard](#postgres-automated-dashboard)
11+
- [Key Value automated dashboard](#key-value-automated-dashboard)
12+
13+
All three dashboards are currently marked Beta.
14+
15+
## HTTP automated dashboard
16+
17+
The "Render/HTTP" dashboard shows request volume and latency for Render web services. Render aggregates these metrics across all instances of a service, so each line corresponds to a host/status_code combination across the whole service rather than to a specific replica.
18+
19+
The following graphs are displayed in this automated dashboard:
20+
21+
- HTTP requests (broken down by status code and host)
22+
- HTTP latency (p50/p95/p99 broken down by host and status code)
23+
24+
These graphs display values from the `render.service.http.requests.total` and `render.service.http.requests.latency` metrics.
25+
26+
## Postgres automated dashboard
27+
28+
The "Render/Postgres" dashboard shows information about Render Postgres instances.
29+
30+
The following graphs are displayed in this automated dashboard:
31+
32+
- Connections (active connections per database, compared against the connection limit)
33+
- Storage size (database size and indexes size per database)
34+
- Transaction volume
35+
- Sequential table scans (per database)
36+
- Transaction exhaustion (per database)
37+
- Slow locks
38+
- Slow lock wait time
39+
- Replication lag (per replica host)
40+
41+
These graphs display values from the `render.postgres.*` metrics.
42+
43+
## Key Value automated dashboard
44+
45+
The "Render/Key Value" dashboard shows connection metrics for Render Key Value (Valkey/Redis) services. CPU, memory, disk and network usage for Key Value services are reported as host metrics and appear on the host metrics dashboard instead.
46+
47+
The following graphs are displayed in this automated dashboard:
48+
49+
- Connections (active connections compared against the connection limit)
50+
51+
This graph displays values from the `render.keyvalue.connections` and `render.keyvalue.connection.limit` metrics.
