Session Propertiers

juanrergis — Wed, 24 Sep 2025 23:13:26 GMT

I have a variable within my application that contains a Key and Value variable. How can I extract the variables to obtain this data from the user sessions? For example: the variable is called "offer." Inside it is a JSON file containing different variables at various levels, payments: 10. I want to obtain payments.
This is done in the session properties to obtain business data.

Hi if you're using RUM JavaScript version 1.295 or later, Dynatrace supports direct JSON parsing from session storage or JavaScript variables.

Example:

If your variable is:

{ "offer": { "payments": 10, "details": { "currency": "USD" } }

And it's stored in sessionStorage.offer, you can extract payments like this:

Go to Application Settings → Capturing → Session and action properties.
Click Add property → Custom-defined property.
Set:
- Expression type: JavaScript variable
- Key: offer_payments
- Value: sessionStorage.offer.$payments
  
  The $ prefix tells Dynatrace to parse the value as JSON and extract the nested key payments.

If your variable is already a JSON string, use sessionStorage.offer.$payments. If it's a nested object, you can go deeper like sessionStorage.offer.$details.currency.

You can also check the official documentation for reference: https://docs.dynatrace.com/docs/shortlink/user-session-properties
