littlefall / cpu-proc-count

count how many threads are running in each cpu.

cpu-proc-count

count how many threads are running in each cpu.

g++ cpc.cpp -o cpc 
watch -n 0.2 ./cpc [proc_name]

TODO

1. set cores as a client parameter.
2. export result to prometheus.
3. support count threads by proc_id instead of proc_name.

example

Every 0.2s: ./cpc tiflash                                                                                                                 Sat Oct  9 18:01:42 2021

will execute: ps -eLo "psr stat pid lwp cmd" | grep tiflash
