Hi,
I am working on setting up a distributed monitoring system with Nagios
(actually Groundwork). I have 3 child servers and 1 parent server, using
NSCA to send passive check results from the children to the parent server.
My question is about how Nagios (version 2.5) will behave when an on
demand host check needs to be run.
So for example:
Host A is configured with check_host_alive ( a simple ping ) as its host
check command on the parent server. It is also configured with Service
A, say an SNMP check. Active host checks are not disabled on the parent
server, but active service checks are.
Host A, obviously, is also configured on the child server. When the
child server sends a passive check result up to the parent saying that
the SNMP check has failed, will the parent server then run the on-demand
host check command to verify that Host A is still up? If not, how do I
get that information up to the parent? Are passive host checks my only
option?
So I guess the question is this: In a distributed monitoring setup, will
a parent server run an on-demand host check for a host that gets a
report (via a passive service check sent from a child server) of a
service being critical?
Thanks,
Tom
