You CAN use SNMP for some of the checks, my in my experience you can’t get everything from SNMP or as detailed info on some things, so I always use NRPE. If you are monitoring the local machine, (localhost) then you obviously don’t need an agent, but if you are monitoring other servers you’ll need with SNMP or NRPE.<o:p></o:p><o:p> </o:p>Dan<o:p></o:p><o:p> </o:p><o:p> </o:p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'>From: Randy White [mailto:randywhite30@neb.rr.com] Sent: Thursday, December 02, 2010 3:38 PM To: 'Nagios Users List' Subject: Re: [Nagios-users] Newbie Question..
