How can I profile only System.String allocations?

Hi AlexKaras,

We use the XPO as ORM in our system and the application allocate a huge amount of memory during an operation.

I would like to find which object takes the most memory.

It is Impossible to switch on the Entire .Net Core by Classes option and log all the loaded objects because the process memory usage more than 10G. The process never finishes.  A lots of small objects are created during the operation.

I suppose the string and the byte objects takes the most memory and try to prove it. I have added the mscorlib.dll to the project (that contains the System.String type) and get information only these objects. (Later I can add other classes as well.)

But the result is empty (see picture below). I suppose my project setup is incorrect.

It would be fine to start an overall allocation profiling session where I see all the types in the process on a high level, only the amount of occupied memory by class not the concrete objects. But I cannot find a way to do it in this application.

I have tried execute the test with less objects but with less objects it is impossible to identify the problematic objects.

I would like to limit the examination to concrete objects like System.String.

Thank you for your help.

Regards,

Csaba
