Christian Beneke c75ba98f81 Documentation/etcd-mixin: Fix EtcdInsufficientMembers alerting 
Currently the EtcdInsufficientMembers alert fires, when more than (X/2)-1
instances are unavailable. This fixes it to fire at the correct limit of (X-1)/2
unavailable instances and $value now contains the number of available instances
instead of unavailable ones. Added unit test for EtcdInsufficientMembers alert.

Prometheus Monitoring Mixin for etcd

NOTE: This project is alpha stage. Flags, configuration, behaviour and design may change significantly in following releases.

A set of customisable Prometheus alerts for etcd.

Instructions for use are the same as the kubernetes-mixin.

Background

  • For more information about monitoring mixins, see this design doc.

Testing alerts

Make sure to have jsonnet and gojsontoyaml installed.

First compile the mixin to a YAML file, which the promtool will read:

jsonnet -e '(import "mixin.libsonnet").prometheusAlerts' | gojsontoyaml > mixin.yaml

Then run the unit test:

promtool test rules test.yaml
