perfview System.FormatException when viewing CPU stacks section in perfview collected from Kubernetes POD

[paraspatidar]

Hi,
I am running dotnet core (2.2.2) process on K8 pod with elevated rights and could do a perf collect without any issue and trace is created as well as CPU stack (perf.data.txt) is created.

However , when coping to windows and opening the CPU stack , it fails with exception :

System.FormatException: Input string was not in a correct format

this happens when we do
`sudo ./perfcollect collect sample'

however if we pass on the process id (-pid param) , then CPU traces doesnt gather at all as mentioned in another issue :
#84

this format issue was said to be fixed in microsoft/perfview#166
but i am using perfview 2.0.26 and facing this issue.

Vance, should we move this issue to the PerfView repo?

[vancem]

Yes, go head and do that.

This is being fixed by microsoft/perfview#890

I am closing this as the fix has been checked into the PerfView repo. Note that a release with that fix has not yet happened (but you can build PerfView yourself if desired).
