The easiest way to monitor Extreme devices (or any comms device, for that matter) is to use SNMP. To do this it's best to have copies of the Extreme MIBs handy so you can get the textual version of the OIDs you want to monitor.

We have several Extreme devices in the installation I run, and I monitor the CPU usage, the memory usage, and the status of uplink interfaces on all of them. CPU utilisation is had via OID

Code: Select all

EXTREME-SOFTWARE-MONITOR-MIB::extremeCpuMonitorTotalUtilization.0
, memory usage is had by performing some basic arithmetic on OIDs:

Code: Select all

EXTREME-SOFTWARE-MONITOR-MIB::extremeMemoryMonitorSystemTotal.1
EXTREME-SOFTWARE-MONITOR-MIB::extremeMemoryMonitorSystemFree.1
EXTREME-SOFTWARE-MONITOR-MIB::extremeMemoryMonitorSystemUsage.1
EXTREME-SOFTWARE-MONITOR-MIB::extremeMemoryMonitorUserUsage.1
in a custom-written perl plugin (a trivial exercise once you've done one or two). The uplinks are monitored via the industry-standard IF-MIB and another custom plugin that's sensitive to a list of uplinks passed in on the command live via a custom host variable that's attached to each host definition for an Extreme switch.
