The network graphs are working for the generic memcache boxes.

I just wanted to update that I am working on this. I am getting results from the munin client on these servers, but the master isn't creating graphs, so I think the next step is to set up a different master to try some config changes without affecting the rest of the current munin setup.

I've set up a second munin master, however it will take some time for it to gather sufficient data before we can compare the existing munin to the new munin. The difference between the two is the new one is runing munin 1.4.4 on Ubuntu, whereas the existing one is munin 1.4.1 on RedHat.

This test should be able to tell us if the problem is on the munin master, or on the munin-node on the box.

As of yet, still undetermined why this graph is blank. The second Munin master didn't change anything, so we are now investigating setting up an instance of Ganglia to do trending.

Assigning to bkero, as he's getting an instance of ganglia set up. Also maybe bkero can look at the munin issue. A second set of eyes is always helpful.

Moving to ganglia.
