EMC VNX Storage: Status and I/O of Disks

Distribution	Official part of Checkmk
License	GPLv2
Supported Agents	EMC VNX

Reports the status and the I/O rate of a disk in an EMC VNX storage system.

Returns OK if the state of a disk is "Unbound" or "Hot Spare Ready" or "Enabled" or "Ready", the number of Hard Read Errors is 0 and the number of Hard Write Errors is 0.

Returns WARN if the state of a disk is "Rebuilding", the number of Hard Read Errors is 0 and the number of Hard Write Errors is 0.

CRIT is returned otherwise.

I/O rates (in Bytes/sec) are just informational and do not trigger any state other than OK

The information is retriefed by the special agent agent_emcvnx which uses EMC's command line tool naviseccli.

If you always get Read: 0.00B/s, Write: 0.00B/s and you think this are not the correct values, please note: Reporting of these data must be turned on at the storage by a command like setstats -on

Item

Consists of bus ID, enclosure ID and disk ID as returned by the agent. E. g. "1/1 Disk 9"

Discovery

One service is created for each disk listed in the agent output.
