etcd-version-monitor

This is a tool for exporting metrics related to etcd version, like etcd server's binary version, cluster version, and counts of different kinds of gRPC calls (which is a characteristic of v3), etc. These metrics are in prometheus format and can be scraped by a prometheus server. The metrics are exposed at the http://localhost:9101/metrics endpoint.

RUNNING THE TOOL

To run this tool as a docker container:

  • make build
  • docker run --net=host -i -t gcr.io/google_containers/etcd-version-monitor:test /etcd-version-monitor --logtostderr

To run this as a pod on the kubernetes cluster:

  • Place the 'etcd-version-monitor.yaml' in the manifests directory of kubelet on the master machine.

Note: This tool has to run on the same machine as etcd, as communication with etcd is over localhost.
