It historically logs that data by default, the default period for that is one week backwards, but I bet it's configurable. It helps us a lot, when somebody points the finger at us to look back what was going on during that time.

the perf advisor is real time right? ie it wont historically log this data and graph it later...
ive used perf advisor in previous dfm releases and liked it but didnt enjoy having to sit and watch it for hours while waiting for intermittent issues to occur :)

If you use dfm a look at the perf advisor might be helpful. Those data is collected via dfm, we use your mentioned figures as well to monitor vol specific statistics.
You can enable/disable and configure the perf advisor options in dfm:
perfAdvisorDisabledCounterGroups perfAdvisorEnabled perfAdvisorMaxMonitorThreads perfAdvisorPollInterval perfAdvisorShowAllViews perfAdvisorShowDiagCounters perfAdvisorTransport
They improved the NMC java client a lot, it's a very helpful utility for specific perf monitoring with lots of detail.
The SDK API also an option, but before putting a script together I would check, if the dfm offers enough for your needs.

Thats far away from SNMP but maybe adoptable to your stats

Excellent, I'm not familiar with that, but I'll certainly investigate.
I don't need SNMP per se. I'm just seeing how I can get the info from the filer with low overhead. I'd rather not fire off a lot of SSH sessions for what I need. So this might be fine. I have DFM, but I can't see that this value is gathered.
Thank you for the pointer. -- Darren
