# *Monitoring* on Fly.io

Debugging a problem you can't see is like stumbling through a dark room covered in Lego blocks. No one deserves the stress, or the pain. That's why Fly.io gives you metrics and logs rather than just suggesting you go and set those up yourself. You get real-time metrics with Grafana and proper detailed logs, right outta the box. No more playing hide and seek with annoying bugs.

## Metrics For People Who Would Rather Be Building

Prometheus and Grafana are awesome. Setting them up and keeping them running? Significantly less awesome. So we run them for you. Get CPU, memory, network, and custom metrics without reading endless documentation about retention policies and storage backends.

- Fully-managed Prometheus + Grafana
- Built-in dashboards out of the box
- CPU, memory, network, disk metrics

- Custom app metrics support
- Real-time metrics updates
- Query with PromQL

## Searchable Logs!

Live tail your logs while debugging. Search through them in Grafana when you're hunting down that user-reported error your can't replicate. Then, export them somewhere else if you want. Your logs, your rules. We just make sure they're there when you need them.

**Live log tailing:** Watch logs stream in real-time with `fly logs`

**Searchable in Grafana:** Query and filter logs without learning yet another query language

**Programmatic access:** Pull logs via API for automation and integrations

**Export anywhere:** Send logs to your existing log aggregation service
