Do you guys know if I can monitor the health of the VPN connections terminating on the ASA using SNMP?
I have seen the Cisco Security Manager and other tools, but I need to know if I can really get this information from SNMP, and if so how?
Yes ASA supports SNMP traps for VPN monitoring
following SNMP traps you can enable on your ASA
asa(config)# snmp-server enable traps ipsec start stop
asa(config)# snmp-server enable traps remote-access session threshold-exceeded
Also I found following discussion here on the forum
Hope that helps rate if it does
