Storing and Collecting Message Logs with Syslog

This chapter provides information about how to use the Syslog feature to store and collect message logs.

This chapter contains the following topics:


Configuring Syslog via CLI

This feature allows you to store system messages and/or errors. You can store to local files on the switch or a remote server running a syslog daemon. Also, it provides a method of collecting message logs from many systems.

The following are examples of the CLI commands used with the Syslog feature.

Example 1: show logging


CODE EXAMPLE 34-1 show logging Command
(DTI SWITCH) 					# show logging
 
Logging Client Local Port	:	514
CLI Command Logging	:			disabled
Console Logging 	:	disabled
Console Logging Severity Filter	:	alert
Buffered Logging	:	enabled
 
Syslog Logging 	:	enabled
 
Log Messages Received 	:	66
Log Messages Dropped 	:	0
Log Messages Relayed 	:	0

Example 2: show logging buffered


CODE EXAMPLE 34-2 show logging buffered Command
(DTI SWITCH) 					# show logging buffered ?
 
<cr>	Press Enter to execute the command.
 
(DTI SWITCH) 					# show logging buffered
 
Buffered (In-Memory) Logging	:	enabled
Buffered Logging Wrapping Behavior	:	On
Buffered Log Count	:	66
