If timeline is not working even for standalone processes, please follow this guide.
Possible case:
Performance counter symbols may not be installed correctly.
To verify the issue:
1) Go to 'Start | Administrative tools | Performance'
2) Right click on plot and select 'Add Counters'
3) Select 'Performance object .NET CLR Memory'
4) Verify that there is no Process ID counter listed
To resolve the issue:
1) Open Command Line (Win+R, type 'cmd', press Enter)
2) At the command prompt, type "unlodctr .NetFramework", and then press Enter
3) Use the 'cd' command to change to the 'C:\Windows\Microsoft.Net\Framework\v2.0.50727' folder
4) At the command prompt, type "lodctr corperfmonsymbols.ini", and then press Enter
I tried all these commands, but for me the following worked well:
This will rebuild the performance counters.
Congrats for dotMemory, great product!
