I have been asked to take snapshot of performance on a windows 2012 R2 server every 10 minutes over the course of a 24 hour period. I need to measure:
1. Overall % CPU Usage: preferably all processors combined.
2. Total % RAM Usage
3. Total % Disk Usage.
I have run some Performance Monitor Data collector sets with multiple counters selected for each measurement and the interval set to 10 Min and exported them to excel, It looks good but I'm not sure which counters will most accurately give me the above metrics?
Is there another tool (preferably free) that would better server my purposes here?
