Hi @vahe. Are logs generated in your configured log directory `/data/deploy/elastic-service/logs`? There should be several with `profiler` in the name, which are created when you run the .NET application. Those might give us a clue as to what's preventing the profiler from attaching. ---

No logs generated 1.25.3, I checked, after agent version 1.22 version profiling do not work. ```auto Maybe it's libelastic_apm_profiler.so? They differ in size 1.22 - 3352152 libelastic_apm_profiler.so 1.25.3 - 3379816 libelastic_apm_profiler.so ``` ```auto 1.22.0 - generate log dotnet_138798_95479731.agent.log elastic_apm_profiler_dotnet_483584_1705338233.log ``` ---

Thanks. The absence of logs suggests .NET is not even picking up the profiler or the profiler failing super early. We'll need to open an issue to investigate this on our end. Are you using .NET 7 for the app target? Is your app running and a systemd daemon? Note that .NET [does not support](https://learn.microsoft.com/en-us/dotnet/core/install/linux-centos) is unsupported on CentOS Linux 7. ---

Is `1.22.0` your lowest working version? Does `1.23.0` fair better? ---

For the sake of experimentation, I moved libelastic\_apm\_profiler.so from 1.22.0 to 1.25.5. I received this error/warn in the log ```auto [2024-01-17T16:48:21.388417906+04:00] [WARN] AssemblyLoadFinished: Elastic.Apm.Profiler.Managed 1.25.0.0 did not match profiler version 1.22.0.0.
