I've received several message for the scripts, but unfortunately I will not be able to share them in their entirety. They really are custom to my environment, but they shouldn't be too hard to create if you know perl.
foreach $controller (@controllers)
{
.....
@output =`dfm perf data retrieve -o $controller -C system:avg_processor_busy -d $duration`;
.....
}
foreach $day(@day)
{
.....
$data->add_point($data_day,$ctrla_values[$array_counter],$ctrlb_values[$array_counter],50,90);
.....
}
print IMG $gd->png;
The result would be something like:

Subject: RE: Metrics!
I wrote custom perl scripts that pull the output of "dfm perf data retrieve," puts it into an array, then uses GD::Graph to plot custom graphs. Graphs are created nightly and can be viewed by navigating to a URL on that server. We graph on CPU utilization, FCP latency, CIFS latency, and overall storage capacity. It's works very well and provides a great high level view of our NetApp storage environment.

Daniel

Subject: Metrics!
We have a growing deployment with ~25 filers and about 750TB of usable space. Most of it is VMware datastore space exposed via NFS, but some is general purpose NAS file sharing.
We've been using OnCommand Core (formerly DFM) to handle reporting and such, and for the most part it's worked pretty well.
I need to start pulling together some metrics for the environment as a whole, both to benefit the Storage Team who manages the devices, but also to be able to pass along to my bosses so they can get a basic grasp of how things are going.
I'm curious how those of you with deployments similar to mine or larger hvae dealt with this? What sort of things are you reporting on, and how do you handle the "roll-ups" to summarize many (in our case 200+) volumes into something meaningful? Are you generating reports natively from OnCommand Core, or pulling the data out into another tool? Do you find the OnCommand DataSets feature useful? We haven't really leveraged it properly I think.
My thought is to present a sort of physical view of our environment showing roll-ups of storage capacity and performance (probably CPU, IOPS and latency). How to give a snapshot overview of the whole environment is what I'm not sure on.
I'm thinking using the DataSets will help me organize our various types of data and then I can report on that.
I'm not sure, however, if I should spend my time trying to get the right reports out of OnCommand Core directly or if I should just start extracting the data to another tool (which?) or into a database where I can home-brew up what I'm after.
Thoughts/experiences?
Thanks,
Ray
