Hi, The problem is that, there are some hosts down for two days, for instance, all unplanned. That makes service checks stop. Some servers are out for 4-5 minutes because of some sophisticated :) construction issues which we are unable to be aware of. I just want them to be checked as usual even they are down. That's all my problem. Host checks are not done as I have configured to be (1 min delay). Do you know a way out of this?

Yes, follow standard setup guidelines and minimize your usage of host checks. Define all your hosts. Configure a host check that runs once and exits quickly; check-host-alive with a single ping is usually sufficient. Have it run a couple of times if you're paranoid (max_check_attempts). *Do not set a check interval, don't even have it in the host definition.* Configure the parents directive for your hosts if you want to take advantage of the network outages logic to minimize notifications. Define one or more services on the host. If the host is pingable only, define a PING service for the host that pings it. Set a normal_check_interval, retry_check_interval and check_period that is sane for your environment. Nagios will check the service in parallel and will only perform a sequential host check when a service fails. Since services should rarely fail, host checks will be run rarely. Since the host check will run and exit quickly, there is minimal interruption of normal scheduling. If all your hosts are pingable only and you don't care about configuring parents then you don't need host checks at all and can set the check_period to none in the host definitions to completely eliminate them. -- Marc ------------------------------------------------------------------------- Take Surveys.
