AnyConnect Tracking Connections and Disconnections

Hello,

 

I am trying to track when users connect to AnyConnect and also when they disconnect per a client request.  I know that the ASA will not show this history except for the current connections.  I have setup a syslog server and tried with message ID lists as well as class and only getting some logs when user disconnects.  Has anyone done this before or know the log ID to create the list?  I have tried searching the buffer as well to get the ID with no luck

 

Configuration below:

 

logging enable
logging timestamp
no logging hide username
logging list VPN_Connections message 722022
logging list VPN_Connections message 722023
logging list VPN_Connections message 722024
logging list VPN_Connections message 722021
logging buffer-size 1048576
logging console informational
logging monitor informational
logging buffered informational
logging trap VPN_Connections
logging asdm informational
logging host inside 10.0.20.7

 

and tried

 

logging enable
logging timestamp
no logging hide username
logging buffer-size 1048576
logging console informational
logging monitor informational
logging buffered informational
logging asdm informational
logging host inside 10.0.20.7
logging class auth trap informational
logging class vpnc trap informational
logging class webvpn trap informational
logging class svc trap informational

Hi

 

You should track the following syslog id 716001 and 716002

 

Take a look here: https://www.cisco.com/c/en/us/td/docs/security/asa/syslog/b_syslog/syslogs8.html#con_4776945

 


Thanks
Francesco

I tried these and for some reason did not send the message ID's to syslog server.  However, I did the following and get info I need with a little extra but think will work...

 

logging enable
logging timestamp
no logging hide username
logging list VPN level informational class vpnc
logging list VPN level informational class webvpn
logging list VPN level informational class svc
logging buffer-size 1048576
logging console informational
logging monitor informational
logging buffered informational
logging trap VPN
logging asdm informational
logging host inside 10.0.20.7
