Host retry interval

[Kyle Tucker]

Thanks Eli,

According to the docs, "Nagios checks the status of a host is when a service 
check results in a non-OK status.". Is that when it reaches a HARD state 
after all iterations of max_check_attempts are done or as soon as it goes to 
non-OK (SOFT) state? If the latter, which seems to be when it's kicking off 
host checks, I don't see how increasing the service checks will help.
