ChunyiLyu commented 2 weeks ago

Context

Setting PprofBindAddress in manager options to serve pprof.

To use:

  1. port forward the controller pod
  2. collect a profile
  3. visualize: 
    
❯ k -n kratix-platform-system port-forward pod/kratix-platform-controller-manager-5c4df4bc77-wtp6z 8082:8082

❯ curl -s "http://127.0.0.1:8082/debug/pprof/heap" > ./heap.out

❯ go tool pprof -http=:8080 ./heap.out Serving web UI on http://localhost:8080



Then you can get CPU time, heap, flamegraph...etc
