Hello ,
were monitoring hosts with about 10 services per host (interval of 5
minutes / retry interval of 1 minute). If some network goes down and many
host are unreachable, nagios checks every(10) service for on host in an
interval of 5 minutes (Its HARD down, i suppose). And if one servicecheck
fails (and this should happen, because its unreachable) it will execute a
hostcheck for this host. This means, nagios is executing 10 hostchecks
per "down" host in an interval of 5 minutes? Right?
Nagios doesnt execute host checks in parallel, isnt it?
Every hostcheck has an plugin timeout of 30 seconds, which in other words
means that only 2 hostchecks per minute are possible. (or 10 checks per 5
Minutes).
Were monitoring about 500 hosts with 3000 services. Timings (max_checks,
interval, ...) are calculated as outlined in the doumentation. If some
network fails (lets say 50 hosts), nagios is only making hostchecks, isnt
it?
And to notify the network operation control, it takes about 50 * 30s = 25
minutes.
Is this the intended behaviour?
I cant work with dependencies, because i didnt get the needed
information.
Or is there something ive dont understand.
