Description

This dashboard monitors the health and performance of a controller-manager component by tracking readiness and request handling metrics. It highlights operational uptime (up), API interaction rates and latency (Kube API Request Rate, Post Request Latency 99th Quantile, Get Request Latency 99th Quantile), and resource utilization such as memory (process_resident_memory_bytes) and CPU usage (process_cpu_seconds_total). Key features include latency distribution via quantiles, queue dynamics with Work Queue Depth and Work Queue Add Rate, and runtime metrics like goroutines to surface concurrency and potential bottlenecks.
