This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
Prometheus is an open-source systems monitoring and alerting toolkit originally built at SoundCloud. Since its inception in 2012, many companies and organizations have adopted Prometheus, and the project has a very active developer and user community.

The metric types counter, gauge and histogram.
Publishing metrics over HTTP (via WAI middleware).
Pushing metrics to the Prometheus push gateway.

Don't forget to actually run the stats collector thread though! For example,
(startGhcStats, registry) <- buildRegistry ghcStats for_ startGhcStats id
