cert-manager Mixin

The cert-manager mixin is a collection of reusable and configurable Prometheus alerts, and a Grafana dashboard to help with operating cert-manager.

Config Tweaks

There are some configurable options you may want to override in your usage of this mixin, as they will be specific to your deployment of cert-manager. They can be found in config.libsonnet.

Using the mixin with kube-prometheus

See the kube-prometheus project documentation for examples on importing mixins.

Using the mixin as raw files

If you don't use the jsonnet based kube-prometheus project then you will need to generate the raw yaml files for inclusion in your Prometheus installation.

Install the jsonnet dependencies (tested against versions v0.20+):

go install github.com/google/go-jsonnet/cmd/jsonnet@latest
go install github.com/google/go-jsonnet/cmd/jsonnetfmt@latest

Generate yaml:

make

To use the dashboard, it can be imported or provisioned for Grafana by grabbing the cert-manager.json file as is.

Multi Cluster Support

It is becoming a common use-case where we run multiple Kubernetes clusters, each one has its own certmanager and Prometheus instance. Those Prometheus remote-write metrics to a remote Long Term Storage, such as Thanos or Cortex, and a Grafana will now query metrics from the LTS tool instead of multiple Prometheus.

Grafana dashboard have now selectors for the queries to the _config jsonnet object.

There is a variable named enableMultiCluster to enable the multi cluster queries for the dashboard.
