[TriLUG] Ubuntu 16.04 NetworkManager Access Logging

[Ron Kelley via TriLUG]

Another tool you might consider is monit (https://mmonit.com/monit).  Monit does a whole bunch of stuff like alert you when CPU/RAM/HDD-space space gets exceeded, automatically restart an app in case the process crashes, etc.

In your case, you can have monit continuously watch /var/log/syslog for your egrep statement below and trigger an alert (or, fire off a script to populate a DB with connection details).

We use monit extensively to watch for resource usage, crashed apps, etc.  It works great and is part of the standard ubuntu repository.

Note: “monit” is free but you can get a license for “mmonit” which allows you to monitor lots of servers using a central dashboard.

What I need is simple connect/disconnect timing without all of the DEBUG information.  Also, sometimes this information is gathered several days later making 'journalctl -u NetworkManager' not optimum.
