License: GPL
Supported Agents: SNMP

This check monitors the state of the packetfilter engine of genuscreen firewalls. It evaluates the pf status, number of used pf states and the maximum number of pf states set for the engine. Warningn and critical limits for the number of used states can be given. If the critical level is not set, the maximum number of states defined for the engine will be assumed.

The check is known to run with genuscreen version 3.0 and 4.1, and supports genuas regular enterprise id 3717 as well as the id 3137 which was introduced in a bug in some versions of genuscreen.
