Munin

If you are using Munin 1.4.x and facing conccurency issues, I highly recommend upgrading to Munin 2.0 which graphs everything on demand using spawn-cgi.

We hit a massive bottleneck with disc I/O at around 100 monitored nodes due to the graphing on each update, resulting in gaps in our graphs.

Moving to Munin 2.0 solves this issue.
