Is there a way to find the number of users that are currently logged into a Django site running on Linux? I need to restart the server and I want to make sure there are 'few enough' people that it won't be too much a hassle.

  • What CMS are you using?

  • First step: define what you mean by "logged in" for your particular use case. Once you've got that out of the way, implementation is trivial.

To see what users are logged into Linux, you can use w or who.

The output of w on my machine:

USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
wesley tty1 :0 Tue12 39:54m 1:34m 0.06s pam: gdm-password
wesley pts/1 :0.0 Tue16 1:38m 0.45s 0.44s ssh [email protected]
wesley pts/3 :0.0 Tue16 1:38m 0.49s 0.47s ssh [email protected]
wesley pts/5 :0.0 Tue20 0.00s 0.25s 0.03s w

The output of who on my machine:

wesley   tty1         2012-02-14 12:28 (:0)
wesley   pts/1        2012-02-14 16:24 (:0.0)
wesley   pts/3        2012-02-14 16:34 (:0.0)
wesley   pts/5        2012-02-14 20:46 (:0.0)

To see which users are logged into an application, such as WordPress or Joomla, will require different, application specific methods, however.


Since you're using Django, you will need to programmatically query the session model for non-expired sessions. Check out the Q/A titled "How to get the list of the authenticated users?" over on StackOverflow for a more thorough explanation.

  • This is a django, non-specific site. I'm basically looking to infer the number from either open sessions or some other method
