I committed a new Munin-plugin for HP P2000 StorageWorks. It monitors through the HTTP XML-RPC interface. It detects all disks, vdisks and controllers automatically – all you need to provide is the username/password, IP-address, and set up some symlinks.
It produces 10 graphs, + subgraphs.
Graph-gallery:
VDISK:
Disk bandwidth and iops (rootgraphs provides enclosures, subgraphs provides disks):
Controller bandwidth and iops:
Controller Cache:
Controller CPU-load:
A sawtooth-graph to indicate uptime statistics for the controllers:
