Enhanced ESP Client Session Logging
This article relates to LoadMaster firmware version 7.2.53.
Client session logging for ESP-enabled Virtual Services has been enhanced in LoadMaster firmware version 7.2.53 to include additional session information:
The initially created ESP session
The time when the LoadMaster cleared the session from the cache. Note that if the entire cache is cleared, a single log message is recorded at the time of clearing, which notes that all existing sessions at that time were cleared form the cache.
If an ESP session is deleted (when the user logs out from the application, when the session expires, or the user enters invalid credentials). The time of when the LoadMaster cleared the session is also logged.
You can view these logs by going to System Configuration > Logging Options > Extended Log Files in the LoadMaster User Interface (UI) and click View for ESP User Logs.
Some example log messages are below:
