How to monitor Local IP Pools on ASA

Question

Is there a way to monitor the availability or usage of Local IP pools on an ASA?  Maybe an OID string that can be pulled by an NMS system.  I would like to be alerted prior to the pool being exhausted.

Answer 1

As far as I know you can check this from your external authentication server so if its cisco acs acting a s radius server for your vpn clients then check under reports and activities >> logged-in user. It will show you the connected user along with the ip address they have got.
Lists all users receiving services for a single AAA client or all AAA clients. Users accessing the network with Cisco Aironet equipment appear on the list for the access point that they are currently associated with, provided that the firmware image on the Cisco Aironet Access Point supports sending the RADIUS Service-Type attribute for rekey authentications.
Note To use the logged-in user list feature, you must configure AAA client to perform authentication and accounting using the same protocol—either TACACS+ or RADIUS.
The same can be checked from the ASA by running
show vpn-session db

From ASDM go to Monitoring VPN >> sessions.
Hope this helps.
