Hello all,
I have a problem where Nagios doesn't execute the active host checks at
all. My system is set up in the following way:
I have about 1000 machines w/ their services set to disable active
check, and get all state info from an external command file (passive
checks).
To this I added 2 hosts w/ services in which I've enabled active checks,
and provided a check command (config below). What happens is the
services get actively checked and updated, but Nagios assumes the host
is up (I guess because the services are returning values), and never
executes the host check. This is troubling because the host check
provides me with important data.
In another instance, I have a host with active check enabled, and its
services' active checks disabled. Here, Nagios just keeps the host and
all its services in a "pending" stage until the services return with
information, again never executing the host check.
Any insight would be extremely helpful. Thanks!
