I’ve come to realize, that CIM is the new SNMP, but on steroids. Most new SAN, NAS, Network, and Operating Systems now support CIM/WBEM. To me it is easier to gather statistics and information through CIM, then it is through SNMP. In this article I am going to give you a script that will allow you to query the 3par for Disk IO stats. You will be able to grab Disk IO stats on a per Volume, per Port, or per Disk basis.You will also be able to search for a Volume, Port, or Disk, instead of just dumping all the Volumes, Ports, or Disk.
Before you download this script, you will need to download pywbem from sourceforge and install it. .
get3ParIOstats.py == Download
All the data that you get from the script, must be saved as a COUNTER and not a GAUGE.
Here is an example of searching for statistics by DISK for DISK 2:6:1..
python get3parIOstats.py -u "http://3par" -a 'login passwd' -s '2:6:1' --diskOK|2:6:1_ReadIOs=67236384 2:6:1_WriteIOs=28457131 2:6:1_TotalIOs=95693515
