Identity Detection Rules

In case Plumbr has not been able to identify the users, you will need to help it find the location of the stored identities. You can do this by configuring the location of the user identity via creating a new  Identity Detection Rule.

Identity Detection Rules can look for the identity of users from two different locations.

In case your application passes along the identity of the user via HTTP Request Headers, you will need to configure a HTTP Header Rule. In such a case, all you need to specify is the name of the HTTP Header from which Plumbr can extract the tracking information. The value for the Header would then be similar to the following:


In case your application does not use HTTP Headers to pass along the identity, you will need to configure a Session Attribute Rule instead. In such a case, you will need to configure two parameters: Attribute Name and Extraction Path.

  • Attribute Nameis the name of the attribute in the session context storing the user’s identity. For example, Spring Security adds its security context under the SPRING_SECURITY_CONTEXT attributeWhen the attribute specified is not found in a particular HTTP Session either because an incorrect attribute name was provided or the application user is not yet authenticated, the Plumbr Agent will not proceed to detect the user’s identity from the Extraction Path.
  • In the Extraction Path field, you should define the exact path where the user identity is stored. For example, if the Spring Security is used, the extraction path used will be getAuthentication().getPrincipal().getUsername().

Combining the two parameters allows Plumbr to look for the identity. Using the Spring Security as an example again and combining the two examples above will result in Plumbr looking for:
