Monitor number of TCP Connections

I need to monitor the number of TCP connections for a Cisco ASA firewall. We have a Web Filter that stops filtering after 750 TCP connections has been reached and I need to know if we exceed this. I can see the info in Cisco's ASDM but I don't want to sit and look at it all day .

Can someone tell me how to monitor this in NPM or Netflow?

Try a universal device poller set up for the OID 1.3.6.1.4.1.9.9.147.1.2.2.2.1.2

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.4.1.9.9.147.1.2.2.2.1.2

Row 2 of this OID should totalOpen connections.

I have created the mib poller and associated with the AS 5520 and the poller is in Node Details but no information is showing up. I put the exact ODS in the poller.

That worked, thanks. I like the second column which shows highest number since last restart.
