I think you can use: GET /v1/sources/swift-cluster-1/projects//meters/ in that case, no? -- Julien Danjou /* Free Software hacker & freelance http://julien.danjou.info */ pgpXLk9LHdkzJ.pgp Description: PGP signature ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

Let's say if you deploy one ceilometer instance for two swift clusters 'swift-cluster-1' and 'swift-cluster-2'. According to the design, if we use 'source' field for region/cluster to tell what cluster the meters come from. The Ceilometer API doesn't seem being well thought through yet. A single region case: If you want to get the meters for TenantA, this API will simply do the job: GET /v1/projects/(project)/meters/(meter) Two regions case: If you want to get the meters for TenantA from 'swift-cluster-1' specifically. According to the API design we have now, there is no API can do that directly unless you do some complex API calls combination.

Hi, >You can deploy several ceilometer and use several databases, or just one and >use a different 'source' field for each of your region/cluster to >differentiate where meters come from. Thanks, Julien, I didn't know source it's meant to be presenting region/cluster info. I guess this wiki should be updated :) http://wiki.openstack.org/EfficientMetering In the field definition, source has two question marks there.

You can deploy several ceilometer and use several databases, or just one and use a different 'source' field for each of your region/cluster to differentiate where meters come from. -- Julien Danjou # Free Software hacker & freelance # http://julien.danjou.info pgpAMx4Vs8WRp.pgp Description: PGP signature ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
