Managing and Manipulating Events 19
Managing and
Manipulating
Events
The Network Supervisor Event List greatly improves your ability to
prioritize and react to problems on your network.
Intelligent Event
Generation
Network Supervisor generates events intelligently. For example, to
prevent utilization ‘spikes’ causing unnecessary events, the threshold set
must be exceeded for a reasonable period of time (determined by
Network Supervisor) before an event is generated.
This means that Network Supervisor will produce a more accurate
representation of what is effectively one incident, than if it generated an
event every time the threshold was passed.
The events in the Event List are generated internally by Network
Supervisor, they are not SNMP traps generated by network devices.
Network Supervisor provides the following to help you manage
generated events:

Filtering
Filtering temporarily removes entries from the Event List to provide a clear
view of a selected type of event. You can filter on various criteria
including event severity, time and description.
Commenting
The Comment facility lets you write and attach notes about events
relating to specific devices or links. You may want to include information
about why an event occurred previously and a suggested solution.
You can then filter events based on the content of a comment, searching
for information to help solve a newly discovered problem.
