I'm working this same question. We are using ASA firewalls and have found two OIDs that are getting me in the right direction. (I believe)

1.3.6.1.4.1.9.10.77.1.2.1 - Gives me the current count of the number of entries in the cnatAddrBindTable

1.3.6.1.4.1.9.10.77.1.2.2.1.7 - Gives me the number of sessions currently using this BIND

These appear to give me the same info as 'show xlate count', the in use and most used data.

Now, I'm thinking I can set an alert to say something like, "if the in use number matches the most used number alert me".

The problem I'm having is that these are custom pollers (one for each OID) I created to pull the data and I'm struggling with alert logic to say that in the SolarWinds alerts.

Not an easy one. Any help here would be GREATLY appreciated.

We used these 2 OIDs:

1.3.6.1.2.1.123.1.4.1.11 is a HEX-STRING of the IP address

1.3.6.1.2.1.123.1.4.1.19 is the amount of ports utilized currently

Still working on writing the report, but this would be a good place to start.
