Host check not performed

[ArDark]

Hello.
Im faced another problem with nagios core 4.1.1 Installed on Centos 7.
Some hosts just not checked by shedule. After enabling full logging ive found some strange logs (this logs repeated every scheduled time to check).
I have around 90 cisco switches that need to be checked by ping. some of them cheched normally, and around 10 is not.
If i ran check by self with force checkbox checked, host checked fine and after again stale :/

Parent Host_Main is available at schedule time and when i force to check host by self.
And no dependencies is set for Host_1, just only one parent.
Any suggestion how to fix this?

Added: fast inspecting full logs, ive fount this issue not only for this host, its Nagios wide (
Configs and log bellow:

Could you post your nagios.cfg file and how these 2 templates are configured?

Code: Select all

generic-host,host-pnp

I'm not sure if the debug output considers parents a "host dependency" clearly something is amiss though.

And no dependencies is set for Host_1, just only one parent.

I'm inclined to trust you, however if that's true this simply reads like a bug. We'll need as much information about your environment to recreate it in our lab so we can file a bug report (if we can recreate it)
Can you `grep dependency objects.cache` before we go down that road?

Please close this topic.
Ive found my error. just configured one child object as master for main host.
and when one of child is down, master wont checked.
DUMB error

Sounds good, glad to see you got it fixed. I will now close this out.
