Prometheus exporter for Reforger SAT stats

Reforger Server Admin Tools Exporter

This program will read the stats file written by Server Admin Tools and export the statistics in a Prometheus-compatible metrics format.

The tool is meant to run alongside the server, and will by default export the metrics on port 9840. It is recommended to run the tools as an unprivileged user, but naturally it must be able to read the file created by SAT.

The command line options are:

Usage of sat_exporter:
  -f string
        file to read stats from (default "/home/reforger/profile/profile/ServerAdminTools_Stats.json")
  -l string
        Labels/values to augment metrics with, in the form label1=val1,label2=val2
  -listen string
        ip:port to listen on (default ":9840")
  -namespace string
        Namespace (prefix) to use for Prometheus metrics (default "reforger_sat_exporter")
  -once
        Only output the stats to stdout and exit (for testing)
  -timeout duration
        Timeout for webserver reading client request (default 3s)

They should be pretty self-explanatory, and usually you only need to use -f.

The option -once is useful to see whether the tool can read your file, and if it outputs credible numbers.
