The
My reading of the code in base/checks.c (SECTION B3) is that if the host check returns non-OK, the service is immediately put into a hard state and no further retries are attempted. Nagios would then fall back to the normal_check_interval for the service check. Beyond the fact that services on down hosts are still checked, your scenario WRT retry_check_interval doesn't appear to happen. > Personally, if a service has a problem like it's down, I usually always > prefer to have it checked more frequently so I can see when it comes back > up > more quickly, especially if I am fiddling with stuff and have another > nagios screen up as well.

Just for clarification, as long as you're within max_check_attempts for your service, then nagios operates with your more frequent check interval. As soon as you reach max_check_attempts or your host check returns a non-OK state, the service falls back to normal_check_interval. -- Marc ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
