I'd vote for that change as it seems counterintuitive to me to not check the status of something that Nagios knows is important (parent or grandparent to all other hosts), and also the average router doesn't really run a "service" IMHO, though ping would have to work to check the status anyway, I think. Sounds like I need to set up a host profile for routers that has at least the ping service. As for active/passive, what you all describe makes sense. It's just not documented that I could find.

Active checks are initiated by nagios itself. The plugin runs on your
nagios machine and actively checks the status of some service. Passive
checks are received by nagios from an external source and not initiated
by nagios. Passive checks are often utilized in distributed monitoring
where you may have one or more other nagios installations performing
checks and sending the results of those checks back to a central nagios
server. Another use for passive checks would be to receive check results
from a script that is running on a machine that isn't directly
accessible by nagios due to a firewall or other circumstance.

Under normal configurations, hosts are never checked until a service on
the host fails. No service, no host checks ever. You must define at
least one service for every host if you want it to be checked. This
requirement is likely to change with nagios-3.

[Nagios-users] Active vs. passive checks; host won't check
Hi,
I'm a relative newbie to Nagios though I have v2.5 set up,
running, and a couple dozen hosts defined. I set it up using Monarch.
Nagios is being used to monitor external hosts (that are not running
Nagios) for uptime and POP/HTTP/etc. services using check-host-alive and
check_http, etc. Parent relationships are defined (internal
router->ext. router->host).
I have two questions, and the first may help to answer the
second. I've never been too sure about the difference between active
and passive checks. What is the difference? Is there a correct time to
use one or the other?
I have one host (a router) that will not check. Status=PENDING
("Host has not been checked yet") forever. Active and passive checks
are both enabled. It is a router, so there are no other services. Also
I used Monarch to clone it from another router's host definition that
was working. Any ideas on why it wouldn't be checking? I can ping it's
IP.
Thanks,
