Remind me why we need this technology again?
That makes no sense. Try looking at logs and such at least.
The logs don't say much. It's mostly the API server getting hammered by nodes and various components.
Ok so it's just the API servers. Not every node which is what it sounded like. Typically you wouldn't run normal workloads on the same host as the API. Although these quick "how I did it" articles have a tendency to skip best practice. Still sounds like something isn't right in your environment. They shouldn't be hammered that hard unless you have a very large cluster.
