Etcd

etcd

Etcd is a strongly consistent, distributed key-value store that provides a reliable way to store data that needs to be accessed by a distributed system or cluster of machines. Configuration of etcd check is stored k8s.ini file in conf directory.

Install
cd ${OE_AGENT_HOME}/checks_enabled
ln -s ../checks_available/check_etcd.py ./
Configure

If you are using default installation of etcd service, no additional configuration is needed. If you need to monitor etc in non default location, edit conf/k8s.ini section etcd and set metrics parameter with value matching your needs.

Restart
