Greetings Salvosmat,

the best way to clean the Ceilometer data in MongoDB is to let Ceilometer do for you through its periodic mechanisms. Configure in /etc/ceilometer/ceilometer.conf the following option to reflect how many seconds you want to save the data:

time_to_live=604800 #one week, should be fine with many installations

However, Ceilometer doesn't phisically delete the data. Find the ceilometer $password in the astute.yaml file on the masternode, and once Ceilometer has deleted the data, shrink physically the database size on the MongoDB master node with this command:

# mongo -u ceilometer -p $password ceilometer
> use admin
> db.repairDatabase()

Best regards,
