How do I check if anyone is currently logged in?

[Boris Kheyfets]

I've a very small number of users, but don't want to disturb them with "canvas is going for maintainance from 1am to 2am". I'd like to check that no one is logged in and do the things I wanted to without an announcment. How do I check if anybody is currently logged in?

Actually found a way: one can expect the /var/log/nginx/access.log when it was last time chainged, and wither it is changing or not.

Hi,

Canvas LMS uses authlogic gem for authentication. (gem 'authlogic', '3.4.6' for current branch)
I have not tried it myself and there's got to be a way to find the logged in users:

How about using the Account Reports API to run the Last User Access report for a particular account?

Checking latest updates in access logs - while sufficient in many ways - seems to replace "see if they are currently logged in" with "see if they left a trail". Has anyone found a solution for this? (Coming to mind: "Presence" in XMPP) - Cheers

Canvas runs over HTTP, which is a stateless protocol. Even if the user has their browser open to Canvas, there is not an open connection to the Canvas servers. So the best you can do is look at recent activity, and surmise if anyone is active. In Canvas on an open source install, this is easy to accomplish by looking at the last_request_at column on the users table.
