List of all sessions

[Ján Raska]

Hi all,
is it possible to somehow get a list of all sessions? I'd like to build some tool for the administrator to be able to destroy some particular sessions if necessary. Also I'd like to have save session counts for site monitoring and optimization.

Thanks

Rusho

To get the session numbers:

import net.liftweb.actor.LiftActor

import net.liftweb.http.SessionWatcherInfo

object SessionMonitor extends LiftActor {

  private var sessionSize = 0

  protected def messageHandler = {

    case SessionWatcherInfo(sessions) => sessionSize = sessions.size

  }

}

SessionMaster.sessionWatchers = 

  SessionMonitor :: SessionMaster.sessionWatchers

  

Obviously the sessionSize variable will then be incremented with the number of sessions. In Lift in Action I describe how you can use this sort of technique with Ostrich to take occasionally gauges on session load. 

Cheers, Tim
