Postgres Mixin

This is a work in progress. We aim for it to become a good role model for alerts and dashboards eventually, but it is not quite there yet.

The Postgres Mixin is a set of configurable, reusable, and extensible alerts and dashboards based on the metrics exported by the Postgres Exporter. The mixin creates recording and alerting rules for Prometheus and suitable dashboard descriptions for Grafana.

To use them, you need to have mixtool and jsonnetfmt installed. If you have a working Go development environment, it's easiest to run the following:

$ go get github.com/monitoring-mixins/mixtool/cmd/mixtool
$ go get github.com/google/go-jsonnet/cmd/jsonnetfmt
