Prometheus Monitoring Mixin for CoreDNS
A set of Grafana dashboards & Prometheus alerts for CoreDNS.
How to use
This mixin is designed to be vendored into the repo with your infrastructure config. To do this, use jsonnet-bundler:
Generate config files
You can manually generate the alerts, dashboards and rules files, but first you must install some tools:
$ go get github.com/jsonnet-bundler/jsonnet-bundler/cmd/jb
$ brew install jsonnet
Then, grab the mixin and its dependencies:
$ git clone https://github.com/povilasv/coredns-mixin
$ cd coredns-mixin
$ jb install
Finally, build the mixin:
$ make prometheus_alerts.yaml
$ make dashboards_out
The prometheus_alerts.yaml file then need to passed
to your Prometheus server, and the files in dashboards_out need to be imported
into you Grafana server. The exact details will depending on how you deploy your
monitoring stack.
