Nimble storage monitoring with check_mk or snmp

[wezelboy54]

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...

Here's the code that assumes milliseconds instead of seconds. The values it produces are consistent.

Hey, what happened to your template on the share ???? cant find it :-( 

And I cant of need et to our new Zabbix setup and new Nimble cs1000

Thx for your help.
