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

Use consistent naming for metrics (prefix_name_unit)

Set appropriate scrape intervals (15-60s typical)

Use recording rules for expensive queries

Implement high availability (multiple Prometheus instances)

Configure retention based on storage capacity

Use relabeling for metric cleanup

Monitor Prometheus itself

Implement federation for large deployments

Use Thanos/Cortex for long-term storage

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'
