Metrics Server

The package go-flexible/flexmetrics provides a default set of configuration for hosting prometheus and pprof metrics.

Configuration

The metric server can be configured through the environment to match setup in the infrastructure.

• PROMETHEUS_ADDR default: :2112
• PROMETHEUS_PATH default: /metrics

Examples

Starting server and exposing metrics

// Rely on the package defaults
srv := flexmetrics.New()
srv.Run(ctx)

// Or bring your own
httpServer := &http.Server{
        Addr: ":8081",
}
srv := flexmetrics.New(
        flexmetrics.WithServer(httpServer),
        flexmetrics.WithPath("/__/metrics"),
)
srv.Run(ctx)

pprof metrics will be exposed on:

/debug/pprof/
/debug/pprof/cmdline
/debug/pprof/profile
/debug/pprof/symbol
/debug/pprof/trace
