Do you use localhost as the host IP? Do you use freshness checking of hosts in the central server?<o:p></o:p> <o:p> </o:p> I had an idea to use scheduled checking of the host on the “Agent” , and send passive host results to the central nagios, if freshness checking discovers the results are not fresh, It runs a script that put “Info: host info is stale”, and will exit with the same error code the host is currently in (from the a macro value),<o:p></o:p> <o:p> </o:p> I think my way of handling this is wrong, as scheduled host checking must be done on the agent, which is bad for performance.<o:p></o:p> <o:p> </o:p> Please share you thoughts/setup, I need some ideas..<o:p></o:p> <o:p> </o:p> Thanks.<o:p></o:p> <o:p> </o:p> Marco.<o:p></o:p> <o:p></o:p> </div> </body> </html>
