Node CPU alerts
HighCPU

Profiling
Section titled “Profiling”If there is an increase in CPU utilization on a single host, you may want to perform CPU profiling or look at profiles from our continuous profiling in Google Cloud Profiler.
For ad-hoc profiling, it is also possible to invoke the profiler on a process directly.
- For Go processes, you can profile via pprof.
- For Ruby processes, you can profile see: [ruby-profiling.md](Ruby profiling).
- For C processes and kernel profiling, you can use perf, see also Redis - CPU profiling.
