Submitted Case #1355478 for resolution. Unfortunately, it seems that NPM 12.2 is not capable of monitoring FirePower Services module on the ASA 5512-X using SNMP traps. The only thing that I found is to create two types of alerts SNMP and Syslog which is supposed to send alerts to the appropriate server but doesn't have the capability to monitor the device itself. The suggestion was creating a MIB in a Universal Poller to accomplish it, but I have not done that yet. If anyone has any ideas, I am open to it.
