HAPTER ONITORING THE ETWORK
Monitoring and Event The monitoring system is used as the main source for generating
Generation events.When a monitor enters a state that indicates an abnormal
network condition it logs an event detailing the cause.Depending upon
the monitor it may also log details of the monitoring state in the time
immediately preceding and following the event.When the monitor later
exits this state it resolves the event.This information can be used either
immediately or at a later date to determine the cause of the event and to
assist with determining a resolution.
For more information on the events system see "Working With Events"
on page 319.
The monitor states that indicate abnormal network conditions are based
upon thresholds.For more information see "Setting Thresholds for
Monitor-Based Events" on page 356.

Monitoring State

3Com Network Director indicates the monitoring state of each monitored
device by coloring the background of its icon in the map and its node in
the tree using one of red, yellow or green.Similarly, the monitoring state
of each monitored link is indicated by drawing the link in the map in red,
yellow or green, rather than in black.This allows you to see at a glance
the current state of your network so that you may quickly identify trouble
spots.
