[munin-users] crazy one for HD temp on MegaRAID LSI controllers

[Rudy <cr...@mo...>]

Got 4 disks in a RAID array using a megasas card? Use this script to get
all the temps on one tidy graph.... one temp climbing faster than the
others? Maybe that one is about to FAIL!!!! Hurry, put some ice on it!
