[TriLUG] Ubuntu 16.04 NetworkManager Access Logging

[Alan Sterger via TriLUG]

Hi Listers,

I need to extract connection timing from accessing my clients VPNs.  
I've looked at /var/log/syslog and 'journalctl -u NetworkManager'.  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.

Any ideas?
