Chapter 7: Event Log and Syslog Servers
104
Event Log Overview
A managed Converteon™ media chassis is a complex piece of computer
that includes both hardware and software. Multiple software features
operate simultaneously, interoperating with each other and processing
large amounts of network traffic. It is often difficult to determine exactly
what is happening when a chassis appears not to be operating normally,
or what happened when the problem occurred.
A network manager’s major task is to monitor the system functions and to
deal with problems as they arise. One method for doing this is to view the
event messages that are generated by the chassis and stored in the event
log. These events can provide vital information about system activity on a
Converteon™ chassis that can help you identify and solve system
problems. The event log includes the following information:
ˆ The date of an event
ˆ The time of an event
ˆ A message of the event
There are two ways that you can view a chassis’ event messages. The
first method is to view an event log. The second method is to have the
chassis send its events to a syslog server. The syslog server functions as
a central repository that stores events from many network devices
simultaneously.
In order for a Converteon™ chassis to send its events to a syslog server,
you must define the syslog output. The syslog output includes the IP
address of the syslog server along with other information such as the
types of event messages you want the chassis to send to the syslog
server.
Note
The event log, even when disabled, logs all AT-S70 initialization
events that occur when the chassis is reset and power cycled. Any
chassis events that occur after the AT-S70 initialization are entered
into the log only if you enable the event log feature. The default
setting for the event log feature is enabled.
