Big-IP APM Sessions and Access Licenses

When a connection is made to a virtual server with an Access Policy , BIG-IP APM automatically assigns a session id to that connection and tracks it with a session cookie and in the session database which uses memcache.

Every Big-IP system has a specific maximum of session it can support.

Session Variables and sessiondump

The sessiondump command is a tool will help us understand Big-IP APM sessions. A session is made up potentially hundereds of session variables that describe the session. Sessiondump display these variables.

sessiondump -allkeys command display every session variable entry in the Access Policy memcache.

sessiondump --allkeys | grep 'session\.logon\.last\.username' command will dump all the current users on BGG-IP APM.

sessiondump --allkeys | grep 'last\.username\|user\.agent' this command will list which user is connecting which user agent.

sessiondump --allkeys | grep 'lat\.username.* ann$' this commadn is used to search for a specisic user.

sessiondum --sid 03b621f6 | wc -l
