Is there a way to monitor /dev/random?

Solution 1:

Sure! Ask /proc/sys/kernel/random/entropy_avail.

Solution 2:

as read someplace else... each new process get entropy from /dev/random

a simple way to avoid stealing the pool is a program, such as:

#!/usr/bin/env python

import time

while True:
    with open('/proc/sys/kernel/random/entropy_avail', 'r') as f:
        print(f.read().rstrip())
    time.sleep(1.0)
