Tuning and Debugging EPICenter
This chapter describes how to tune EPICenter performance and features to more effectively manage
your network. It also describes some advanced features that are available to an EPICenter administrator
(a user with an Administrator role) to help analyze EPICenter or Extreme Networks device operation.
These include:
• Monitoring and tuning EPICenter performance
• Tuning the alarm system
• Using Device Groups to facilitate workflow
• Using the EPICenter MIB Poller tools to maintain MIB variable history
• Reconfiguring EPICenter ports
• Using the EPICenter debugging tools
Monitoring and Tuning EPICenter Performance
If you are using EPICenter 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 EPICenter. Some of these you can affect with various settings in
EPICenter. 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 EPICenter 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 120.
• 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 EPICenter server.
• The size of the worker thread and the maximum number of SNMP sessions that can be running.
Taking a Device Offline
If a device is scheduled to be taken down for maintenance, you can set that device offline in the
EPICenter database. EPICenter will not attempt to poll or sync with the device and will ignore all traps
from the device while it is offline. This means that any events caused by the maintenance activities will
not cause alarms in EPICenter.
