Hi Rohan-
I made some changes to your check_mk plugin that add more per volume performance metrics.
It seems to work, but I think there may be some kind of undocumented unit mismatch because my numbers appear to be off by at least a factor of 1000.
My question to the nimble developers is...
Is it possible that this MIB entry-
volStatTimeEpochSeconds OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"Time at which the sample was taken, measured in seconds since UNIX epoch."
::= { volEntry 12 }
should actually be milliseconds instead of seconds?
I was thinking maybe byte counters might actually be kbyte counters, but the rates are low for IOPS as well.
It's also possible that I screwed something up and can't see it.
Here's the code...
