CPU Usage (Precies) appears normally in WPA.
CPU Usage (sampled) does not appear in Graph Explorer -> Computation.
Opening a saved WPA profile that previously contained CPU Usage (Sampled) results in an empty graph, similar to:

If I have understood you correctly, an existing ETL file that previously showed CPU Usage (Sampled) no longer does that.
Can you post a screen snapshot (using that file), making sure that the items highlighted in yellow have been expanded and are visible (if present)?

2026-01-22T22:50:35.15+00:00 Sorry, could've been more clear in the original post.
The existing ETL file has never showed CPU Usage (Sampled) in Computation Dropdown Menu.After opening the ETL file, I don't see CPU Usage (Sampled). So I tried opening a saved .wpaProfile file that contains that table in the analysis tab. Profile > Apply... > Select .wpaProfile. The dropdown is empty as shown in the screenshot.
I'm not sure how you opened System Configuration > Trace Statistics. Are there additional steps I need to do when recording with wpr?

Can you try issuing the command
wpr -resetprofintimmediately before starting a trace collection with sampled profiling and let us know if that makes any difference?Gary

I am running for a total of 17 seconds.
Benchmark runs for ~10 seconds.

Did you try using a simplified profile, as mentioned in the thread that you cited in your first message? I don't know why that worked for Tony, but I don't have any other suggestions.

2026-01-23T15:57:56.36+00:00 Hi Gary,
I've tried both simplified profiles mentioned in the thread with Tony a few times, and I get the same results.
Thank you for your suggestions so far :-)
