Nagios Support Forum

We are testing Nagios XI and find the server monitoring is excellent.

Unfortunately we are having trouble monitoring an Ethernet switch.

1. We are unable to see device availability, CPU utilisation or memory utilisation. What do we need to do to get this information?

2. In addition, we get weird and wonderful port names. What can we do to import more meaningful names … e.g. Port 1, Port 2 etc.

Please find below the output we have so far.

Many thanks - Tarquin belling

Switch information is generally obtained through SNMP. Some or all of it may be restricted to only allowed hosts, so you may need to use your switch's configuration interface to make sure the Nagios server is allowed to "see" the information you want. The naming scheme should also be passed from the switch, although if you can't change that on the hardware you can at least rename the Nagios services after the fact. You'll likely find more information in the user manual for your specific model of network switch, particularly if there's a section on SNMP access.
