Check the NRPE Documentation, specifically the troubleshooting section. It sounds like the commands you are executing are taking longer than ten seconds to execute. Try increasing the timeout value for these commands.<o:p></o:p> <o:p> </o:p> Example from the NRPE documentation: /usr/local/nagios check_nrpe –H localhost –c somecommand –t 30<o:p></o:p> <o:p> </o:p> -Jason<o:p></o:p> <o:p> </o:p> <o:p> </o:p> </div> </body> </html>
