The hotspots section in DT automatically displays the most important hotspots in the service but we observed that for a few services, we cannot see those details.Can someone share how these hotspots are created and what might be the reason if these are not present?
Solved! Go to Solution.
@Rashmi G. we had the same issue. Generally, hot spots are calculated every 50ms-150ms or so. Therefore, if you have requests that are longer than this, then I would expect it to work. However, if you have a short request, then hotspots should not be automatically expected to show. With that said, I do not think that this is the problem.
However, there is a setting that I want you to enable.
Please go to Settings >> Server-side service monitoring >> Deep monitoring >> New OneAgent features > Filter for "Prefer .NET" >> you should see the feature called "Prefer .NET method hotspot information via CLR"
About that setting: "Enable this to use an improved implementation of .NET method hotspot information for applications running on .NET Framework 4.6"
Please enable it
It requires a restart too
