Kubernetes monitors should use the relabel component internally instead of of their own implementation #888

Open mattdurham opened 3 months ago

mattdurham commented 3 months ago

Request

The kuberenetes monitors have relabel rules but do not use the caching in the relabel component which can create issues with CPU.

Use case

Reduce cpu

what's this problem means?

mattdurham commented 3 months ago

With an extreme number of labels the CPU will skyrocket instead of using the relabel component internally that has a cache to handle this situation. In reviewing some issues we found that there were high CPU spikes whenever service monitor went to relabel that would have been addressed with using a cache.
