If you really want a 1 minute window then that means that you'll either have to check multiple times per minute (max_check_attempts>1, interval_length<60) or check only once and trust that as definitive (max_check_attempts=1, interval_length=60). You'll probably want to re- visit the plugin timeouts, both in nagios.cfg and any that are directly supported by the plugins themselves. If you go with the multiple checks per minute path, you'll need to change the value of interval_length in nagios.cfg and every other *_interval, both in nagios.cfg and in your host/service/notification definitions since they are simply multiples of interval_length. Be prepared for false-positives unless things are perfect all the time. I expect you'll see alerts for non service affecting things such as slower ssh logins on busy machines or high RTA or maybe some packet loss as routers get busy and de-prioritize ICMP traffic. The more frequently you check, the more likely you are to encounter those types of things. -- Marc ------------------------------------------------------------------------------ Come build with us!
