Re: [Question #251723]: High CPU Usage for carbon-cache?

 

Question #251723 on Graphite changed:
https://answers.launchpad.net/graphite/+question/251723

    Status: Needs information => Answered

Jason Dixon proposed the following answer:
I've seen this when carbon-cache is blocking on writes. If you're using
relays look for the existence of carbon.relays.*.destinations.*.queuedUntilConnected
and carbon.relays.*.destinations.*.fullQueueDrops metrics.

Also, check your carbon.agents.*.cache.queues metrics.
