Whiteboard
We need to be careful about how we implement this. We don't want users publishing their own meter data, right? - dhellmann
Should the API send the data out onto the message bus in case there are other listeners interested in receiving it? Maybe as an option? - dhellmann
Does this mean, even third party service(eg. ganglia gmond) can send the monitoring metrics via this API? will those data pollute the openstack-specific meters from the storage point of view? - shengjie
How about:
If the user/admin wants to publish a counter with a source != "their ip addr" they need to do this as
admin or a dedicated meter-posting-user. Else we accept the meter but the source gets set to
something like "user:<the posters ip addr>". Then it will be easy to ignore the data when doing
billing.

Allow posting samples via the rest API

[Matt Rutkowski] The impl. of this API has to make sure that user injected data (e.g. even by admins) is clearly separated and marked from automated data. In other words, admin submitted data cannot masquerade as components providing their own manual data (intermixed). It is important to remember that this metric data is used beyond development purposes and by providers for billing (usage) and for verifying SLA agreement for performance are met. Auditors of the data need to confirm that all component/automated data was not tampered with in order to certify a provider.

Good point. We are addressing that by ensuring that the "source" field for the data is unique and tied to the project of the user submitting the data. That provides a way for clients to filter their queries to ensure they get only the desired data. Does that address your concerns? - dhellmann

[nijaba] This BP is marked as implemented but as far as I can tell this is done by:

which states that this works only for admins, so I wonder if this is completely implemented?
[jd] This commit seems to allow posting to project the user is authenticated too
