Regarding the metrics available, should we add a metric handler to the simulator server ? WDYT about having our own frontend charts to show these metrics like [dashboard](https://github.com/kubernetes/dashboard/blob/d0ce152691da04b19783ccbf05f804f6f934cc97/src/app/frontend/resource/cluster/node/detail/template.html#L17) (probably need...

+1 for the SimulatorName for each different scenarios!

Per discussion on sig-scheduling [slack thread](https://kubernetes.slack.com/archives/C09TP78DV/p1647967672841409), the motivation for this feature is to correlate and identify the root cause of high latency spike in scheduling latency. The potential outcome of...

ping ~ are we okay to work on this ?

> This requirement of "correlating scheduling latency spikes with metrics" is valid to me. It's just I'm wondering if `pluginMetricsSamplePercent` is the most efficient way to understand the correlation? Can...

@sanposhiho Thanks for pinging me ! Sure I will get myself to work on it. I have been busy and forgotten about this, nevertheless still an important feature for me...

@sanposhiho @Huang-Wei Sorry for the delay, I have started working on this issue and created a [branch ](https://github.com/matthewygf/kubernetes/tree/plugin_sampling) locally. I have taken the direction to add ```add pluginMetricsSamplePercent to KubeSchedulerConfiguration```,...
