It's when you start wanting to read CPU status, chassis temperature and fan speed you need to delve into the enterprise branch of the snmp tree. -- Andreas Ericsson [EMAIL PROTECTED] OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 - This SF.net email is sponsored by: Splunk Inc.

Re: [Nagios-users] Switch Port Monitoring Advice
What I don't understanding, at the moment, is do I have to setup each of the ports as an individual host? Obviously the check_host_alive would check the switch itself is online and would not really be relevant to each of the ports. I was thinking of some kind of Link Status service, where I could pass a port number or group of port numbers, and get a status returned. In terms of 3Com switches, I see quite a lot of Cisco specific scripts and was wondering if anyone had done anything with 3Com switches. In particular I was interested in the uplink ports and traffic throughput.

Re: [Nagios-users] Switch Port Monitoring
> Anyone like to share how they monitor switch ports? Here, we use MRTG to graph the switch ports, and the routers2 frontend to MRTG to make it pretty. Also, the routers2 frontend has a Nagios plugin to allow the Nagios data to be displayed as well -- and a portstatus plugin to show the current individual port configuration and status. For Nagios, we use a simple ping service and then use the hostextinfo url to link to the MRTG graphs page. On some switches, we also have a CPU use service. We also have an SNMP trap service and the switches send SNMP traps to the Nagios host which are parsed and relayed to the appropriate service. Port up/down etc generate traps which can in turn generate alerts. Finally, for key switch ports, and additional service can be defined for that particular port status OID. It should be possible to do something similar for port traffic thresholding, but we dont. Steve Using Tomcat but need to do more? Need to support web services, security?

Re: [Nagios-users] Switch Port Monitoring
Robert, What I typically do is monitoring the switch with a PING, the I setup services group(s). I have many switches that I watch gig0/1 as an example as this is the port that interconnects all the other switches. I have been grouping services groups based on the port that I monitor, and then add the hosts/hostsgroups. If you want to view ALL the ports, you can do that as well. Check out the "check_snmp_int" command.
