PM monitor data is missing

[buaastv_yzl]

Hi, I am using cuda SDK 12.3, and a docker container environment. All the metrics can be collected from ncu, including the source SASS and ptx info. But the PM monitoring does not show anything,

The data set FULL have already been enabled. Is there anything else I should do to get PM sampling data?

Hi, @buaastv_yzl

I am sorry for the issue you met. But it is expected in CUDA12.3.
You can see related reply here PM sampling doesn't work - #10 by felix_dt. PM Sampling support in container will be enabled in our next Nsight Compute release.

I have try on a bare metal environment(2023.3.1), but it does not show L2 metrics how can i fix it?

You can edit the section file for PmSampling to make it occur on the timeline.

sorry, I dont know how to edit, can you show more details?

There is PmSampling.section in sections folder. You can add details like below. Pay attention to your GPU filter.
