Irule for session Creation and Close

From your post, it sounds like you'd like to generate a report about incoming APM session:

• Login timestamp
• Logout timestamp
• Calculate login/logout to get a session duration
• Username

The APM logs contain sufficient information to generate such a report. The report log lines have the session ID number as a key, so you have to basically create a map of all session IDs and Check /var/log/apm for the correct lines with timestamp for session start, end, and username. Check the log file when you create a login and logout, they're straightforward. APM also has a report function to perform this task, but the amount of data stored is rather small because the disk on BIG-IP itself is used, and the size is limited. We recommend using syslog to send the logs to another device.
