The cert-manager mixin is a collection of reusable and configurablePrometheus alerts, and aGrafana dashboard to help with operatingcert-manager.

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 inconfig.libsonnet.

See thekube-prometheusproject documentation for examples on importing mixins.

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

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

go install github.com/google/go-jsonnet/cmd/jsonnet@latestgo 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 thecert-manager.json file as is.

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 namedenableMultiCluster to enable the multi cluster queries for the dashboard.
