However I would now like to get something going live that would allow us to monitor our network better. The current scenario is that in our office basement server/comms room we have 4 x Cisco 2950G Series switches which we use as core switches (in a fail over configuration) for our server/firewall connections. These switches then connect to 2 fibre media convertors. These convertors connect to the rest of the building network via a fibre cable which runs up the length of the building terminating on each of the 3 floors of our office. Thus every floor operates independently of any other. On each floor there is a fibre transceiver which connects to a Cisco 2950 Series switch (not G series).<o:p></o:p><o:p> </o:p>My questions are:<o:p></o:p><![if !supportLists]>1. <![endif]>What is the best setup to monitor the failover status of the core switches as well as bandwidth over the uplinks?<o:p></o:p><![if !supportLists]>2. <![endif]>What is the best setup to monitor the activity/bandwidth over the fibre transceivers which are connected to each floor’s switch uplink port?<o:p></o:p><![if !supportLists]>3. <![endif]>I’ve also had a quick look at Fully Automated Nagios (FAN). Do you think this would be the best way to get started or building something from scratch?<o:p></o:p><![if !supportLists]>4. <![endif]>If using FAN is not a good idea, which O/S would be the best to run Nagios on (we use Solaris and RHEL mostly)?<o:p></o:p><![if !supportLists]>5. <![endif]>If using FAN is not a good idea, which add-ons etc. would be useful for visuals (GUI, graphs etc.) and configuration?<o:p></o:p><o:p> </o:p>Really sorry for all the questions (there will probably be more at some point). Many thanks for your time.<o:p></o:p><o:p> </o:p>Regards,<o:p></o:p>Rab.<o:p></o:p>=============================================================<o:p></o:p>Robert Jackson Phone: +44 (0) 141 332 7999<o:p></o:p>IT Manager Fax: +44 (0) 141 331 2820<o:p></o:p>Walker Martyn Ltd<o:p></o:p>1 Park Circus Place Email: <a href="mailto:rab@walkermartyn.co.uk">rab@walkermartyn.co.uk</a><o:p></o:p>Glasgow G3 6AH, Scotland Web: <a href="http://www.walkermartyn.co.uk/">http://www.walkermartyn.co.uk</a><o:p></o:p>=============================================================<o:p></o:p><o:p> </o:p></div>************************************************************************ The information in this internet E-mail is confidential and is intended solely for the addressee.
