Additionally to that, depending on the switch, I also check the Cisco Stack status, the memory usage and either a single port or several port ranges for their operational status. <o:p></o:p> <div> On Fri, Aug 13, 2010 at 1:25 PM, Jim Avery <<a href="mailto:jim@jimavery.me.uk">jim@jimavery.me.uk</a>> wrote:<o:p></o:p> <div> On 13 August 2010 10:20, Robert Jackson <<a href="mailto:rab@walkermartyn.co.uk">rab@walkermartyn.co.uk</a>> wrote: > I’m currently on Nagios Core 3.2.1 and I’m just starting to setup monitoring > of our network switches.

Other than that, I monitor link bandwidth where it really interests me, for example on the ports serving our most busy systems and one or two which link main data centres together. The usual rule with Nagios parent relationships is that the parent is the device closer to the Nagios server than the child. Don't forget you can have more than one parent if that's how your network is. hth, Jim<o:p></o:p> <div> <div> ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge <a href="http://p.sf.net/sfu/RIM-dev2dev" target="_blank">http://p.sf.net/sfu/RIM-dev2dev</a> _______________________________________________ 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<o:p></o:p> </div> </div> </div> <o:p> </o:p> </div> ************************************************************************ The information in this internet E-mail is confidential and is intended solely for the addressee.
