Python module for ganglia 3.1.
This module allows you to collect available entropy on your system. Why is entropy important.
[http://www.chrissearle.org/node/326]
There are two random number sources on linux - /dev/random and /dev/urandom. /dev/random will block if there is nothing left in the entropy bit bucket. /dev/urandom uses the same bucket - but will not block (it can reuse the pool of bits).
Therefore if you are running SSL on the box you want to know this.
Copy entropy.py from python_modules to your python modules directory e.g.
/usr/lib64/ganglia/python_modules
and entropy.pyconf to
/etc/ganglia/conf.d/
Restart Gmond and you should be set.
