Nagios Support Forum

Hello team,

I am using Nagios for about 3 years now and it is a great tool, thanks for all your work!

Service dependency checks reduce the number of checks and alerts we receive if master service is down, how about the reverse functionality?

Is it possible to reduce the number of checks if slave is up? For example if a Web Server on VM is up then Vm is up and the Host for that Vm is UP.

Can I check the Web server and assume that VM and Host are up and not to check them in Nagios? If yes how to enable this functionality?

Thanks.

Vitalie.

Maybe you can with some shifty use of inheritance, but it seems like you are unnecessarily overcomplicating the situation, if this is purely for the exercise of resource efficiency you will be doing so at the cost of the sanity of the next person who has to maintain that system.

If it's a performance issue there are probably more pragmatic ways of solving this problem such as off-loading or removing high utilization services, using a proxy server at remote sites for bandwidth concerns or even "throw more resources at it" for once might have merit.
