Monitoring

By default, Dragonfly allows HTTP access via its main TCP port (i.e, 6379) and it exposes Prometheus compatible metrics on :6379/metrics.

Check out this complete example of setting up a Grafana Monitoring Stack with Dragonfly.

** ⚠️ **

If you're using kubernetes, Metrics are also available on admin port 9999. You may encounter this error with port 6379:

* Request completely sent off
* Received HTTP/0.9 when not allowed
* Closing connection
curl: (1) Received HTTP/0.9 when not allowed

Replication Metrics

The /metrics endpoint also exposes replication information. These metrics include details about the replication role of the instance, connected replicas, and replication lag, allowing you to monitor the health and status of your Dragonfly replication setup via Prometheus.
