how can I get the CPU usage in percent of my app ?

[John0King]

I want to get the CPU and Memory usage of my app in .net core, for .net framework , I can use PerformanceCounter class, I have read a few docs about the EventCounter class , but it seems not able to get the info from it.

Do you want to use them programatically? Or just see them?

• To see them we have the dotnet-counters global tool.
• You can see some sample usage of the diagnostics client library.
• Using EventListener on the RuntimeEventSource you can do it in-proc. You can get an idea maybe starting on the Listener

Or have you tried this and still get no information back? What version of the dotnet runtime are you using in this case?

There are also programmatic options using properties on System.Diagnostics.Process. https://docs.microsoft.com/en-us/dotnet/api/system.diagnostics.process.totalprocessortime?view=netcore-3.1

@hoyosjs
I'm using .net core 3.1, And I want to use it in-proc (show CPU usage and refresh every few seconds ).

Using EventListener on the RuntimeEventSource you can do it in-proc. You can get an idea maybe starting on the Listener

The RuntimeEventSource is internal how do I use that ? Is there a sample ? and does the PerformaceCounter work on Linux ?

@John0King You can use EventListener to subscribe to System.Runtime EventSource. Here is a sample EventListener implementation on how to do that: https://github.com/dotnet/diagnostics/blob/master/documentation/design-docs/eventcounters.md#sample-code

PerformanceCounter only works on Windows. EventCounter is the recommended cross-platform API.
