Overview

Package deucalion provides an easy-to-use Prometheus metrics server.

The deucalion package provides an automatic Prometheus server that will start automatically when the PROMETHEUS_ADDRESS environment variable is set. To use the deucalion package only for the automatic metrics server, you may import it as:

import _ "github.com/hemilabs/heminetwork/service/deucalion"

After being imported, the application may be run with the PROMETHEUS_ADDRESS environment variable set to an address to start the Prometheus metrics server:

PROMETHEUS_ADDRESS=localhost:2112 myapp

The deucalion package may also be used to create a Prometheus metrics server with custom collectors:

d, _ := deucalion.New(&deucalion.Config{
    ListenAddress: PrometheusListenAddress,
})

_ = d.Run(ctx, []prometheus.Collector{})
