Xperf Summary window messed

Question

I am trying to use Xperf. It worked fine for some time, but suddenly, when I tried to see CPU Sampling Summary table it looks messed like that:

The Simplefied Summary is ok but misses information. Any help?

Answer 1

the yellow bar is important. Drag a column on the left side of it to sort the data.

Answer 2

The orange bar is crucial. Everything to the left of the orange bar is used for grouping. Columns to the right of the orange bar are used for data display, and can be used for sorting, but are not used for grouping.

If you want to group by process and then stack then the column order has to be process, stack, orange bar.

But! Don't be constrained to just that grouping. It can be useful to group by thread ID, so enable that column and throw it in there. The Zen of summary tables is knowing how to fearlessly enabled/disable/rearrange columns.

Take a look at these two articles: https://randomascii.wordpress.com/2012/05/08/the-lost-xperf-documentationcpu-sampling/ and https://randomascii.wordpress.com/2012/05/05/xperf-wait-analysisfinding-idle-time/

Answer 3

Well... it seems that what you have to do is click between Line and Process, right above the orange column and drag it right.

If someone will ever need it...
