To clean up old ceilometer data in OpenStack, perform the following steps:
- First of all, stop the Telemetry service.
systemctl stop openstack-ceilometer-collector openstack-ceilometer-notification openstack-gnocchi-metricd openstack-gnocchi-statsd openstack-aodh-evaluator openstack-aodh-listener openstack-aodh-notifier openstack-ceilometer-central
- Stop MongoDB service by entering the following on shell prompt.
systemctl stop mongod
- Delete all files in /var/lib/mongodb and then restart MongoDB.
cd /var/lib/mongodb
rm -r *
systemctl start mongodb
- Create a MongoDB master node.
mongo --host MONGOHOST --eval 'rs.initiate()'
- Fing listener IP by entering the following command.
ss -tlnp|grep mongo
- Add resulting IP to MongoDB replication file.
mongo --host MONGOHOST --eval 'rs.add("controler1_mongodb_IP:PORT"); rs.add("controler2_mongodb_IP:PORT"); '
- Create a ceilometer database.
mongo --host MONGOHOST --eval 'db.getSiblingDB("ceilometer").addUser({user: "ceilometer", pwd: "MONGOPASS", roles: [ "readWrite", "dbAdmin" ]})'
- Start Telemetry service using systemctl.
systemctl start openstack-ceilometer-collector openstack-ceilometer-notification openstack-gnocchi-metricd openstack-gnocchi-statsd openstack-aodh-evaluator openstack-aodh-listener openstack-aodh-notifier openstack-ceilometer-central
