Monitoring

Monitoring endpoints are configured in the global.monitoring section of the config file.

Prometheus & Grafana

zrepl can expose Prometheus metrics via HTTP. The listen attribute is a net.Listen string for tcp, e.g. :9811 or 127.0.0.1:9811 (port 9811 was reserved to zrepl on the official list). The listen_freebind attribute is explained here. The Prometheus monitoring job appears in the zrepl control job list and may be specified at most once.

zrepl also ships with an importable Grafana dashboard that consumes the Prometheus metrics: see dist/grafana. The dashboard also contains some advice on which metrics are important to monitor.

Note

At the time of writing, there is no stability guarantee on the exported metrics.
