Watchlog | Effortless Server Monitoring, No DevOps Needed

1. Install Watchlog Agent

2. Configure Integration

After installing the agent, open integration.json in your agent directory and add the PostgreSQL block:


  {
    "service": "postgresql",
    "monitor": true,
    "host": "localhost",
    "port": "5432",
    "username": "YOUR_USERNAME",
    "password": "YOUR_PASSWORD",
    "database": ["postgres"]
  }

2.5. Enable Query Performance Metrics (pg_stat_statements)

Edit postgresql.conf:

shared_preload_libraries = 'pg_stat_statements'

Restart PostgreSQL:
```
sudo systemctl restart postgresql
```
Enable the extension: Connect to each database and run:
```
CREATE EXTENSION pg_stat_statements;
```
Verify: Execute:
```
SELECT * FROM pg_stat_statements LIMIT 5;
```
to confirm the extension is active.

3. Restart Watchlog Agent

Linux Restart
