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.

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.
