<div dir="ltr">I think i've found a bug. in config.c: At line #1878, temp_service->check_interval is incorrectly assuming interval_lenght=60, but if one would use an interval_length directive equals to 1, then the Warnings like: "[1220575781] Warning: Service 'Current Load' on host 'faeroes' has a notification interval less than its check interval! Notifications are only re-sent after checks are made, so the effective notification interval will be that of the check interval." will incorrectly shows up, because the conditional below assumes interval_lenght = 60. (line 1878) if(temp_service->notification_interval<temp_service->check_interval && temp_service->notification_interval!=0){ I don't know exactly where the interval_length could be fetched to correctly multiply by the value of check_interval and compare it to the "in minutes" value of notification_interval and send a patch, just saw these warning on a new install with interval_length = 1, and I think i might report it. Sorry if this is a known bug and/or if i've missed something. HTH, Marcel </div>
