Embedded node_exporter

The goal of this project is to make a version of node_exporter that is easily embeddable into another golang application. While this is considered an "anti-pattern" for prometheus exporters as discussed here there are sometimes still use cases where including the exporter is the better solution.

Usage

The following example creates and registers a new NodeCollector with some basic collectors and no logging for the collectors.

import (
    exporter "github.com/craumix/embedded_node_exporter"
)

nc, err := exporter.NewNodeCollector(
    nil,
    "cpu",
    "hwmon",
    "meminfo",
    "stat",
    "diskstats",
    "netstat",
    "time",
    "filesystem",
)
if err != nil {
    log.Panic(err)
}
err = prometheus.Register(nc)
if err != nil {
    log.Panic(err)
}

The collectors use https://github.com/go-kit/log for logging so you can either use that or write a translation to your own logger. A translator for logrus is already included and may be used as an example for further use cases.

level := logrus.WarnLevel

nc, err := exporter.NewNodeCollector(
    &exporter.LogrusTranslator{
        LogLevel: &level,
    },
    "cpu",
)

The LogLevel can be optionally specified, if not set will use ur default log level.
