Ceilometer rest api, only most recent results?

I'm trying to fetch a bunch of ceilometer data through rest api. I tried to get list of instances, so I fetch instance list through rest API url:

http://IPADDR:8777/v2/meters/instance

But for a relativly small cloud (10 instances) response json is over 45 mb in size. After further investigation it seems that ceilometer returns data from multiple dates for every instance.

I could filter it through simple query to fetch only entries after certain point, but how to get only the most recent entries for every instance?

Thank you!

Solution

  • there is a limit parameter you can pass in: http://docs.openstack.org/developer/ceilometer/webapi/v2.html#get--v2-meters-(meter_name)

    as a sidenote, you can also ask questions to openstack-dev and openstack-operators mailing lists
