Apply request attribute as filter to multidimensional analysis tools

CarlosTF — Tue, 06 May 2025 09:52:22 GMT

Hello everybody.

I've been using the 'Custom multidimensional analysis' to get the 'Request Count', filtering by Service types and by custom 'service tags' and 'process group tags', and spltting by dimension {Request:Name} to successfully get a list of top web request.

Now , I would like to narrow my querry a bit more by using a request attribute (yet to be done) as value to narrow the filter.

The results I've got so far look like these:

/bi/eu/checkout
/health/probe.html
/ma/ca/ginbi/1/authentication/loginInfo
/bc/ca/ginbi/1/authentication/loginInfo
preferences
/lu/ga/checkout

I would like to create a request attribute called 'region' that would use the following regex:
^/([a-z]{2})/
Which means that in case the request looks like this:
/**/co/whatever -> It will get the value of the two characters between the 2nd and 3rd '/' character.

By doing this. When for example filtering by: Request attribute: region = "ca" --> it should only return:
/ma/ca/ginbi/1/authentication/loginInfo
/bc/ca/ginbi/1/authentication/loginInfo

I've tried unsuccesfully different approaches by using these datasources:
Capture Web request URL path globally
Capture Web service method name globally
Capture Web request URL path globally
Capture Web request URL globally

But I only see the request attribute created and attached to traces but not to web request.

It is possible to get this done?

Any help about whjat can I be doing wrong?

Thank you in advance.

Hi @CarlosTF ,

I just want to confirm if I understood correctly, based on your message, the request attribute has been created and is being captured successfully, and you can see it in the traces. However, you’re looking to include this request attribute in the request name, correct?

If that’s the case, you can achieve this by creating a request naming rule that utilizes the request attribute.

Let me know if that helps or if I misunderstood anything.

Hi @CarlosTF

in addition to the available resource, kindly make sure that Dynatrace headers aren't blocked through Firewall or Network devices as per https://docs.dynatrace.com/docs/observe/digital-experience/web-applications/initial-setup/firewall-constraints-for-rum#headers

on the other side, validate the CMC related configurations

BR,

Peter

No, thanks to you guys:

I forgot to add something

I've finally got it working when setting it like this:
Data type -> text

All disticnt values
To upper case
Allow this request attribute to access unmasked personal data. (Enabled)

Add new datasource:
Request attribute source: Web Request URL Path
Specify where the attribute is captured and then stored: Capture from both client ans server side and store where found.
Also in the 'Further restrict or process captured parameters (optional)' section:
Prune whitespace: Enabled
and
Extract value from captured data per regex: ^/([a-z]{2})/

This time, this is the right solution.

Thanks again
