<div dir="ltr">Tom, Are all the values the same, for each piece of information on all the hosts? It sounds like you've got your hosts inheriting service checks, which has resulted in all of them inheriting the default local service checks for your Nagios server. As for best ways to monitor systems remotely, I've used NRPE previously, due to its simplicity, but SNMP makes things easier in the long run. Matt -- Mathew S.

I do not recall doing anything special that would allow this info to be returned...is it possible that the remote Linux box has a service that Nagios tries to connect? Basically Nagios was setup to just monitor, which I figured it would only be successful with pings, however it's obviously gathering much more info. Any help would be great...also if there is a better way to gather data, that would be helpful too. thanks in Advance! -- There's no place like $HOME. ------------------------------------------------------------------------------ _______________________________________________ Nagios-users mailing list <a href="mailto:Nagios-users@lists.sourceforge.net">Nagios-users@lists.sourceforge.net</a> <a href="https://lists.sourceforge.net/lists/listinfo/nagios-users" target="_blank">https://lists.sourceforge.net/lists/listinfo/nagios-users</a> ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null </blockquote></div> </div>
