PerfStack Data Transforms

PerfStack Data Transforms

I would like to be able to add data-transforms to PerfStack.  For example, if a storage system tells me both Total Free Space and Total Used Space, I want to add a data-transform graph that takes those two and calculates % Free Space.

Or if i have a poller that gets total diskIOReads and Writes and I have a transform that gives me IOPS/sec, I'd like to put that transform on a PerfStack...

monitoringlife, the type of transforms available in PerfStack today are analytical algorithms which allow for identifying things like anomalies or trends in the data. They cannot be used to perform mathematical formulas against multiple different metrics to derive a completely different metric. While that would be a pretty cool feature, I'm not entirely sure PerfStack would be the right place for it, as I can imagine use cases for things like alerting on those calculated values or adding them to a report.

I'll provide a use case

If you've got a clustered environment and you're monitoring the same metric on a farm of different nodes, it would be nice to see all those metrics totaled together to provide you with a single line in Perfstack. In my case, and the reason I found this thread, I'm trying to monitor the total number of SIP calls in VNQM across our publisher and 3 subscribers. I get a line for each Call Manager but it would be nice to have a total displayed in Perfstack. This metric is not available in SNMP, and maybe not even AXL. I'm really not sure how VNQM is pulling this data, but I'd put my money on witchcraft.
