Find out max CPU of application

Cheetah Designs · 3 Feb 2014 at 22:24

I have an application that I wish to find out what the peak CPU usage is over a set period of time. Ie what is the highest amount of CPU it had used in that period.

Even better would be a graph of CPU vs time. The time will be about 1.5 hours roughly.

How can I do this?

I assume this is a windows based application?

If so go start and run perfmon, you can set specific app monitoring in the monitoring tools screen.

Or a free program "process explorer" can show cpu history.

Perfmon is what you want. It can log in the background and had loads of flexibility on how and what you log.

Just trying to figure out what I want with perfmon. I can get a graph of my application, set it to 1000s but I don't really know how to read the graph.

It would appear the processor % time is above 100% which doesn't really make sense to me?

Can you take a screenshot of what you options you chose in perfmon?

Does this show what you want?

Processor time in excess of 100% is quite normal on a machine with multiple cores.

Right so do I divide it by the number of cores?

It's a sum of processor time so yes I suppose you could, but if you're just looking to see what's pegging your CPU over time a conversion isn't necessary as you can just compare like-for-like.
