@exekias Tests somehow fail on darwin. Probably need to skip it. |

Should we make this configurable?

It's a little tricky cause it's a global cache. I used a somehow safe value, I don't think someone needs to worry about it, what do you think?

How about init it directly here
var PerfMetrics = NewPerfMetricsCache()

Sounds good to me, pushed the change, thanks!

This PR adds the following set of calculated metrics for Pods and containers:
kubernetes.container.cpu.usage.node.pctkubernetes.container.cpu.usage.limit.pctkubernetes.container.memory.usage.node.pctkubernetes.container.memory.usage.limit.pctkubernetes.pod.cpu.usage.nanocoreskubernetes.pod.cpu.usage.node.pctkubernetes.pod.cpu.usage.limit.pctkubernetes.pod.memory.usage.byteskubernetes.pod.memory.usage.node.pctkubernetes.pod.memory.usage.limit.pctAs the source of data to calculate these values comes from different places (kubelet & kube-state-metrics) I added a mechanism to share some performance metrics through an in-memory cache. For that reason, these new metrics will only be available when
state_*metricsets are enabled.After talking with @simianhacker, I think this:
closes #6125
closes #6124
Please @simianhacker have a look and let me know if you need anything else
