Host checks are necessary for determining status and reachability of network hosts (through parenting) as well as suppression of all SERVICE notifications on hosts that are down; a single HOST notification would go out instead. -- Marc -- The NEW KODAK i700 Series Scanners deliver under ANY circumstances!

See http://nagios.sourceforge.net/docs/3_0/networkreachability.html If you have no other active checks for that node, then I would normally recommend configuring ping as both host and service check, as it just makes it easier to see what's going on in the Nagios cgis. If you are already actively monitoring other services (for example FTP) on the host, then personally I wouldn't bother having ping as a service check too (I'd just use ping for the host check). You might want to use different parameters for the host check ping, for example if you want the host check to send more pings with a longer timeout than the service checks to make absolutely sure the host is really 'down'. On the other hand, you might want to make your host checks really simple and quick so that Nagios doesn't get bogged down doing host checks if you have a major network outage affecting a lot of hosts. hth, Jim -- The NEW KODAK i700 Series Scanners deliver under ANY circumstances!

[Nagios-users] checking host alive or service ping check
Hello all, What is the difference between checking a host is alive with a check in the host template (check_command check-host-alive), witch I have defined as a PING. And creating a ping service applied to the host ? I did a test with both configurations, and didn't see a different behavior. The only big advantage I have with the Ping is the graphics witch I really need, so I am wondering if I could disable host-alive check, and make it depend on the ping service check? BTW I use centreon. cheers, www.felipeferreira.net -- The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
