Demonstrations of pidpersec, the Linux eBPF/bcc version. This shows the number of new processes created per second, measured by tracing the kernel fork() routine: # ./pidpersec Tracing... Ctrl-C to end. 18:33:06: PIDs/sec: 4 18:33:07: PIDs/sec: 5 18:33:08: PIDs/sec: 4 18:33:09: PIDs/sec: 4 18:33:10: PIDs/sec: 21 18:33:11: PIDs/sec: 5 18:33:12: PIDs/sec: 4 18:33:13: PIDs/sec: 4 Each second there are four new processes (this happens to be caused by a launcher script that is retrying in a loop, and encountering errors). At 18:33:10, I typed "man ls" in another server session, which caused an increase in the number of new processes as the necessary commands were run.
