Hi Luc,
Thanks for the prompt reply.
Using a SQL DB is not bad a idea, but maybe a little overkill for my needs, although it if were running longer it might be worthwhile. Realistically, I'm probably going to run it for a week, so that's only 7x24x2 records to store in total, a CSV should do I guess.
If I'm understanding correctly, do you think doing a point-in-time calc based on the last 30min of data is the way to go for the data-collect.ps1 script, then just schedule that to run.
I really wanted to get an opinion on what Im trying to do is a good way of doing it (which it sounds like it is), and maybe some sample code. I think I can figure out which counters, if you have a sample get-stat command handy that may be helpful. The logic I should be able to figure out....
So, I'll have a crack.
