## Internal Monitoring (Already Configured)

The following internal monitoring is already set up:

### Docker Health Checks
- **Umami Container**: `curl -f http://localhost:3000/api/heartbeat`
  - Interval: 10 seconds
  - Timeout: 5 seconds
  - Retries: 5

- **PostgreSQL Container**: `pg_isready -U $POSTGRES_USER -d $POSTGRES_DB`
  - Interval: 5 seconds
  - Timeout: 5 seconds
  - Retries: 5

### Automated Backups
- **Schedule**: Daily at 2:00 AM
- **Retention**: 7 days
- **Location**: `~/umami-backups/`
- **Script**: `~/umami-deployment/backup-umami-db.sh`

### Disk Usage Monitoring
- **Schedule**: Daily at 3:00 AM
- **Warning Threshold**: 80% disk usage
- **Critical Threshold**: 90% disk usage
- **Location**: `~/umami-backups/disk-monitoring.log`
- **Script**: `~/umami-deployment/monitor-disk-usage.sh`

## Verification

To verify monitoring is working:

1. **Check Endpoint Manually**:
```bash
curl -I https://analytics.agenticgovernance.digital/api/heartbeat
# Should return: HTTP/2 200
```

2. **Test Alert Flow**:
   - Stop Umami container: `docker stop tractatus-umami`
   - Wait for alert (should arrive within 10 minutes)
   - Restart container: `docker start tractatus-umami`
   - Verify recovery alert

3. **Check Internal Monitoring**:
```bash
# View Docker health status
docker ps

# Check backup logs
tail -20 ~/umami-backups/backup.log

# Check disk monitoring logs
tail -20 ~/umami-backups/disk-monitoring.log
```

## Alert Response Procedures

### Analytics Down (5+ minutes)
1. Check Docker container status: `docker ps`
2. Check container logs: `docker logs tractatus-umami`
3. Check PostgreSQL status: `docker logs tractatus-umami-db`
4. If needed, restart: `cd ~/umami-deployment && docker compose restart`

### High Disk Usage (>80%)
1. Check backup retention: `ls -lh ~/umami-backups/`
2. Remove old backups manually if needed
3. Check PostgreSQL volume: `docker exec tractatus-umami-db du -sh /var/lib/postgresql/data`
4. Consider database cleanup or server upgrade

### Database Corruption
1. Stop Umami: `docker compose stop umami`
2. Restore from backup: `~/umami-deployment/restore-umami-db.sh ~/umami-backups/umami_backup_YYYYMMDD_HHMMSS.sql.gz`
3. Restart services: `docker compose up -d`
