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.
