I'm curious as to what all you other 3PAR users monitor? Do you monitor IOPS, thin provisioned storage vs. actual storage available, etc?
Are you just pulling data from the InServ itself or are you using system reporter?
Inquiring minds want to know.
I'm currently monitoring IOPS as a whole and percentage used on drives, but I'm sure I can get a lot more granular to look for trends as well as better reporting to the bosses.
What specifically do you monitor?
Re: What specifically do you monitor?
We use System Reporter and it is a awesome tool. I run over 2 dozen daily reports. I have overall IOP reports that run against the entire array as well as then reports for given sets of front end ports since we send different workloads into different front end ports. I then have reports on the various physical disk performance (7K, 10K 15K) so I can see how a given class of disk is performing. We then run reports for specific VLUNs to show how individual apps are performing. Because this all gets generated via the Apache engine in SR I then point users to the URL and they can see how their various apps are running on the back end and can look at thay before they call me to blame storage.

PD LATENCY!
This will help detect drives that are spewing CRC errors but fly under the radar of S.M.A.R.T. disk failure detection. 1 naughty drive was responsible for random latancy spikes across multiple hosts, multiple ports... it was a bear to trace and discover.
Mine is set as:
statpd_fc15
total_svctms
limit value=75
limit count=5
I also alert on NL/Sata iops over 80 and FC iops over 180.
Port latency might also be a good consideration for an alert.

We are using system reporter and setup all the reports that were specified in a PDF that our installation engineer had from 3par support which were pretty comprehensive. I need to look into alerting.

Do you have that PDF by chance that you would share?

Yeah, never seen that pdf, would love to see it.

Sorry for the long delay, forgot about your request.
See Section 13 of this pdf.
