You have a million host on your nagios monitoring-system. You know that you must to disable 2/3/5/x service-check on all host, as the used method of check was corrupted / the monitoring-script failed / SELinux fix was not implemented until now….. One, common way that you login to nagios’s web-interface then disable check’s notification & check & add comment to it step-by-step, so in separate steps. Another way that you have some kind of premium / paid solution for nagios that solve this problem. I will explain a third built-in poor but effective tool for these kind of tasks. With this knowledge & with a little bit of scripting knowledge you will have ability to do your task within seconds.
With these commands you haven’t got any feedback / result. It is one-way communication. If you declare your command to a non-exist service / host, you will left as blind… no any return-code. But you can check on nagios’s page 🙂

Non-working check at the moment Comment, what I want to add to the service.
>/var/spool/nagios/cmd/nagios.cmd It depends on what is the path of external-command’s interpretative file.
