Split transactions using request data based on custom expression on HttpRequest for .NET Core

Hi there,

I have a problem splitting transactions using request data while using custom expression on HttpRequest. My application is .NET Core running in a ECS Task.

The custom expression described here (https://docs.appdynamics.com/21.9/en/application-monitoring/configure-instrumentation/transaction-detection-rules/uri-based-entry-points) does not work.

When using "${Url.ToString().Split(Char[]/-).[2]}-${UserAgent}" no transaction gets instrumented.

While it is returning "Microsoft.AspNetCore.Http.DefaultHttpRequest" when using "${Url.ToString()}".

Any ideas?

Thank you 😉

Hi @Bogdan.Parcalab,

Is there part of the Doc that didn't make sense, or the instructions just didn't work? If you share a bit more details, I can share this with the Docs team.

Hi,

It does not work. I cannot split transactions by following the exact example from documentation!

Below two configurations does not for work for me. They are not creating any business transaction.

When testing with " ${Url.ToString()"} only, I got a business transaction named "<my_business_transaction_name>.Microsoft.AspNetCore.Http.DefaultHttpRequest". Like in the bellow photo, which clearly does not look like an URL.

And yes, "aspdotnet-core-instrumentation=" is set to "HTTP" for the tier.

What am I doing wrong here?

Can you point me to the right place in the documentation where I can learn how to split my business transactions, with custom rules based on the request URL?

Or maybe where I can see some logs, so that I can investigate the evaluation of my custom rule.

Thank you,

Bogdan
