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.
[etcd]
metrics : http://127.0.0.1:2379/metrics
Restart
${OE_AGENT_HOME}/oddeye.sh restart
