Prometheus Configuration

Complete guide to Prometheus setup, metric collection, scrape configuration, and recording rules.

Purpose

Configure Prometheus for comprehensive metric collection, alerting, and monitoring of infrastructure and applications.

When to Use

  • Set up Prometheus monitoring
  • Configure metric scraping
  • Create recording rules
  • Design alert rules
  • Implement service discovery

Detailed patterns and worked examples

Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.

Best Practices

  1. Use consistent naming for metrics (prefix_name_unit)
  2. Set appropriate scrape intervals (15-60s typical)
  3. Use recording rules for expensive queries
  4. Implement high availability (multiple Prometheus instances)
  5. Configure retention based on storage capacity
  6. Use relabeling for metric cleanup
  7. Monitor Prometheus itself
  8. Implement federation for large deployments
  9. Use Thanos/Cortex for long-term storage
  10. Document custom metrics

Troubleshooting

Check scrape targets:

curl http://localhost:9090/api/v1/targets

Check configuration:

curl http://localhost:9090/api/v1/status/config

Test query:

curl 'http://localhost:9090/api/v1/query?query=up'
