Hooks a database up to Grafana Cloud Database Observability: sampled queries, explain plans and per-digest metrics, with no changes to application code.

## What it does

The skill walks the agent through setup for both engines. On PostgreSQL it turns on `pg_stat_statements` via `shared_preload_libraries`, restarts the server, creates a `grafana_monitoring` role holding `pg_monitor` plus `CONNECT` on the target database, and confirms the extension with a count query. MySQL needs less: a user with `SELECT`, `PROCESS` and `REPLICATION CLIENT`, plus a check that `performance_schema` is on.

Then Alloy does the shipping. You paste in a `database_observability.postgres` or `database_observability.mysql` block, restart Alloy, and the first scrape lands after about a minute. In Grafana Cloud the instance should show up with a non-empty `db_query_total{db_instance="mydb"}` series. Nothing after two minutes? Read the Alloy log for connection errors first.

Managed instances such as RDS or Cloud SQL already ship `pg_stat_statements` — it is just switched off. Enable it through the parameter group or flag, then create the extension inside the database. The monitoring credentials are yours to create; Alloy has nothing to connect with otherwise.

## Requirements
- Works with: Grafana, PostgreSQL, Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill database-observability -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/database-observability/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/database-observability/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill database-observability -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/database-observability/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill database-observability -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/database-observability/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install grafana/skills database-observability
```

2. **Manually: put the files in place**
- File: `.github/skills/database-observability/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill database-observability -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/grafana/skills --path skills/grafana-cloud/database-observability
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/database-observability/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill database-observability -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/grafana/skills/tree/HEAD/skills/grafana-cloud/database-observability/SKILL.md

## When to use it
- turn on `pg_stat_statements` and confirm it answers
- set up a separate least-privilege monitoring user
- add PostgreSQL or MySQL collection to Alloy
- rank slow queries by digest and view their explain plans
- tie a slow SQL statement back to a service trace via `db.statement`

## Example prompts
- Set up Database Observability for my RDS PostgreSQL: enable query stats and create a monitoring role
- MySQL feels slow — wire it into Grafana Cloud through Alloy and show the top queries by mean latency
- Why is my instance empty in Grafana Cloud? Check the Alloy log and `pg_stat_statements` permissions

description: Set up Grafana Cloud Database Observability for MySQL and PostgreSQL — enables `pg_stat_statements` / Performance Schema, creates a least-privilege monitoring user, configures the `database_observability.postgres` / `database_observability.mysql` Alloy components, ships query samples + visual explain plans + RED metrics + schema details to Grafana Cloud, and correlates slow queries with application traces via `db.statement` / `db.system` OTel attributes. Use when monitoring database performance, diagnosing slow queries, setting up DB observability for RDS / Aurora / Cloud SQL / Azure Database / self-managed instances, correlating DB metrics with APM, or alerting on query latency — even when the user says "my database is slow", "find the slow queries", or "monitor RDS" without saying "observability".

# Grafana Cloud Database Observability

> **Docs**: https://grafana.com/docs/grafana-cloud/monitor-applications/database-observability/

Query-level insights (RED metrics, query samples, explain plans) for MySQL and PostgreSQL without application code changes. GA since April 2026.

## Common Workflows

### PostgreSQL setup

```sql
-- 1. Enable pg_stat_statements (requires restart)
--    In postgresql.conf:  shared_preload_libraries = 'pg_stat_statements'
--    Then restart PostgreSQL.

-- 2. Create a least-privilege monitoring user
CREATE USER grafana_monitoring WITH PASSWORD 'secret';
GRANT pg_monitor TO grafana_monitoring;
GRANT CONNECT ON DATABASE mydb TO grafana_monitoring;

-- 3. Enable the extension on each monitored DB
CREATE EXTENSION IF NOT EXISTS pg_stat_statements;

-- 4. Verify
SELECT count(*) FROM pg_stat_statements;
-- Should return >= 0 (not an error). If "relation does not exist": step 3 didn't run.
```

5. Add the [Alloy config block from references/alloy-config.md § PostgreSQL](references/alloy-config.md#postgresql)
6. Restart Alloy and wait ~60s for first scrape
7. **Verify in Grafana Cloud** → Database Observability — the instance should appear with non-empty `db_query_total{db_instance="mydb"}` series. If empty after 2 minutes: check Alloy logs for connection errors, then re-verify pg_stat_statements permissions.

### MySQL setup

```sql
-- 1. Create least-privilege monitoring user
