The MMS Monitoring documentation states:
MMS Monitoring provides support for collecting and charting hardware statistics collected with Munin.
From what I can gather, the MMS Agent only has support for three munin-node plugins:
We should probably list these explicitly either on the configure monitoring page (or another suitable place) just so people aren't left wondering if it's working correctly or not.
In the troubleshooting steps, we do mention:
telnet [HOSTNAME] 4949
however, it's not clear that this list is exclusive, nor that iostat_ios maps to the iotime graph.
