Description Eric Jones 2016-11-03 20:52:41 UTC
Description of problem:
Recently a customer started seeing an issue with whichever node has the hawkular-metrics pod on it using near 100% of its CPU. There is a single java process that appears to be owned by the hawkular-metrics pod that is using this vaste amount of CPU

There is not enough information attached here for us to proceed.

Can you please attach the Hawkular Metrics logs?

Is this running on a small machine without a lot of CPU resources to begin with? Or running on a more heavy duty machine with lots of CPU resources available?

The Hawkular Metrics pod can also be set with resource limits to limit the CPU amount the pod is allowed to access. But if the pod is already using a lot of resources, then it might already be using what it requires.
