Monitoring

Centrifugo supports reporting metrics in Prometheus format and can automatically export metrics to Graphite.

Prometheus​

To enable Prometheus endpoint start Centrifugo with prometheus option on:

config.json
{
    ...
    "prometheus": true
}

This will enable /metrics endpoint so the Centrifugo instance can be monitored by your Prometheus server.

Graphite​

To enable automatic export to Graphite (via TCP):

config.json
{
    ...
    "graphite": true,
    "graphite_host": "localhost",
    "graphite_port": 2003
}

By default, stats will be aggregated over 10 seconds intervals inside Centrifugo and then pushed to Graphite over TCP connection.

If you need to change this aggregation interval use the graphite_interval option (in seconds, default 10).

Grafana dashboard​

Check out Centrifugo official Grafana dashboard for Prometheus storage. You can import that dashboard to your Grafana, point to Prometheus storage – and enjoy visualized metrics.
