openfire offile notification/trigger

Question

I am using openfire for chat application in iOs and php website. and everything is working fine.

I have also implemented push notifications when opponent user is offline and you are sending a message to that user (in short push notification for offline message). I have implemented above stuff which is available here : Openfire offline notification through PHP

Now, client asks me to implement one more feature which includes :

Send mail to admin when any user goes offline.

But now there is no any hook available to track user status. So how to implement the same ?

What I tried

I also tried one trick in which I am sending broadcast message to all users and if any user is offile then my CallbackOnOffline plugin will invoke, but here its not sending broadcast message to offline users.

You can give a try to "intercept" Presence packet with Presence.Type.unavailable

Openfire has a ConnectionCloseListener (in SessionManager class) that fires a Presence unavailable.

If you read the class comments, it says

  // Send an unavailable presence to the user's subscribers
  // Note: This gives us a chance to send an unavailable presence to the
  // entities that the user sent directed presences

so probably it's possible to have an administrative user who can auto-subscribe to all users, recive the presence-unavailable and so you'll be able to just intercept the packet direct to this user to send your e-mail.

With opposite logic you'll be able to force a direct presence to something you control and intercept presence-unavailable to this entity
