Scaling munin

Running a large munin master is all about herding bottlenecks. Memory, CPU and storage IO are candidates for "bottleneck of the day"

Munin used to be cron driven.

Then we got CGI.

My first commit to the munin project was in 2007.  

I mostly care about the Munin Guide (https://munin.readthedocs.org), and the plugin documentation.  From time to time, I dig into the perl code of Munin, but not very often.

I am also the sysadmin for the Munin project servers.  I take care of our Trac instance, and did the migration of the project from subversion to git in 2012.
