Faythe also provides the simple /healthz endpoint with the member uptime.
Faythe uses Prometheus for metrics reporting. The metrics can be used for real-monitoring and debugging. Faythe does not persist its metrics; if a member restarts, the metrics will be reset.
The simplest way to see the available metrics is to cURL the metrics endpoint /metrics on its client port. The format is described here.
Follow the Prometheus getting started doc to spin up a Prometheus server to collect Faythe metrics.
The naming of metrics follows the suggested Prometheus best practices. A metric name has an faythe prefix as its namespace and a subsystem prefix (for example cluster).
