I am currently trying to push request attribute data to Splunk for additional reporting not currently offered in Dynatrace. I've created a request attribute on a request called login that contains a messageType parameter in the Referer field. If this value = loginFailed, I count that as a failed login. The multidimensional chart is filtered on login request and failed login request attribute. Using the Dynatrace API, I am able to push the service method request count of the login, but I cannot find an option to filter those by the request attribute. Is this possible?
