Thanks to @barthez, he introduced #58 new gauge sidekiq_host_processes which is also able to show if the process is quiet.
# HELP sidekiq_host_processes The number of processes running on the host.
# TYPE sidekiq_host_processes gauge
sidekiq_host_processes{host="host01",quiet="false"} 2
sidekiq_host_processes{host="host01",quiet="true"} 1
sidekiq_host_processes{host="host02",quiet="false"} 1
It will appear in the renewed Docker image and Helm package soon ™️
Happy coding! 🎉
