274CHAPTER 7: MONITORING THE NETWORK

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.
