   An APM administrator is troubleshooting an access policy that fails during the HTTP request phase.

What should the administrator do?

   • AUse SessionDump to extract the session table entries for the affected user and review the policy variables.
   • BIncrease the log level of the access log to 'debug' and wait for the next request to be logged.
   • CRun the F5 Troubleshooting Utility (tmsh) with the 'sys db' option to capture all database variables related to the access policy.
   • DEnable the web engine trace for the affected virtual server and reproduce the issue, then review the trace output.
