Re: [Openstack] [ceilometer] How does ceilometer work with multi-DC scenario
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. I think you can use: GET /v1/sources/swift-cluster-1/projects/project/meters/meter in that case, no? I actually didn't see this API you mentioned above defined anywhere.

We can probably add that in the API anyway. :) -- Julien Danjou // Free Software hacker freelance // http://julien.danjou.info pgpLWvbNocQJb.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
Re: [Openstack] [ceilometer] How does ceilometer work with multi-DC scenario
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. 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.

[Openstack] [ceilometer] How does ceilometer work with multi-DC scenario
Hi, Has anybody come across the scenario you need to deploy two or more openstack swift or nova clusters for whatever DR or HA reasons. How Ceilometer is going to cope with that? Just wondering is there any plans or blueprints addressing the usage data replication/distinguish/isolation among multi-DCs?
