Chapter 6: Event Logs and Syslog Servers

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 sent to the event
log. This events can provide vital information about system activity on a
Converteon chassis that 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 logs, even when disabled, log 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 logs only if you enable the event log feature. The default
setting for the event log feature is enabled.
