C H A P T E R
This chapter describes how to tune Ridgeline performance and features to more effectively manage your
network. It also describes some advanced features that are available to an Ridgeline administrator (a
user with an Administrator role) to help analyze Ridgeline or Extreme device operation. These include:

Monitoring and tuning Ridgeline performance

●
Tuning the alarm system
●
Using Device Groups to facilitate workflow
●
Using the Ridgeline MIB Poller tools to maintain MIB variable history
●
Reconfiguring Ridgeline ports
●
Using the Ridgeline debugging tools
●
Reconfiguring the FreeRadius server
●
Monitoring and Tuning Ridgeline Performance
If you are using Ridgeline to manage a very large number of devices in a large network, you may can
encounter times when the performance of the system can seem slow. There are a large number of factors
that can affect the performance of Ridgeline. Some of these you can affect with various settings in
Ridgeline. In other cases, you may be able to affect the overall performance of the system by
considering how you manage specific devices in your network.
There are a number of factors that can affect Ridgeline performance:
The amount of alarm processing the system is attempting to handle. This is discussed in some detail
●
in the section "Tuning the Alarm System" on page
The frequency and timeouts for SNMP polling and MAC polling (if you have it enabled)
●
The processor power and amount of memory available on the system running the Ridgeline server.
●
The size of the worker thread and the maximum number of SNMP sessions that can be running.
●

Disabling Ridgeline Management for a Device

If a device is scheduled to be taken down for maintenance, you can disable Ridgeline management for
the device. Ridgeline will not attempt to poll or sync with the device and will ignore all traps from the
device while it is unmanaged by Ridgeline. This means that any events caused by the maintenance
activities will not cause alarms in Ridgeline.
