I have 2 firewalls and was wondering how I would be able to make my servers on the DMZ depend on the 2 firewalls being available.
Thus the availability of the servers on the DMZ depends on FW1_1 and FW_2 being up.
See below my the entries for my tests;
Test List:
FW_1
FW_2
Host_1
Host_2
Host_3
Dependencies
Host_1,Host_2 & Host_3 depends on FW_1 & FW_2 being UP.
Expected Result
FW_1 & FW_2 are Down THEN do not check Host_1,Host_2 & Host_3 - Just alarm FW_1 & FW_2 are DOWN.
If FW_1 is UP & FW_2 is Down THEN check Host_1,Host_2 & Host_3 - Just alarm FW_2 is DOWN
If FW_2 is UP and FW_1 is Down THEN check Host_1,Host_2 & Host_3 - Just alarm A is DOWN
My problem is when both FW_1 & FW_2 goes down - I receive multiple alerts informing me of FW_1 & FW_2 being down as well as the various hosts on the DMZ.

Probably you use "Synchronize status & alerts" option? When the option is turned on, besides synchronizing counters, the dependent test receives the status of the master test, which in turn will start action dispatching based on the status propagated from the master test.
>If FW_1 is UP & FW_2 is Down THEN check Host_1,Host_2 & Host_3 - Just alarm FW_2 is DOWN
If FW_2 is UP and FW_1 is Down THEN check Host_1,Host_2 & Host_3 - Just alarm A is DOWN
Its a problem. If test depends on several Master tests, HostMonitor use AND logical operator. It means HostMonitor will perform Host_1..Host_3 checks only in case BOTH firewalls are alive. If any firewall goes down, HostMonitor will not perform dependant tests.
