Testing the Syslog Sever Configuration

Problem

You want to test the configuration of your syslog server to ensure that the log messages are stored in their correct location.

Solution

The Bourne shell script in Example 18-2 emulates syslog messages at various severity levels to ensure that your server routes them to the correct location. By default, the script will emulate syslog messages to the local7 syslog facility, since Cisco routers default to local7, but the logging facility is completely configurable. No arguments are required or expected.

Example 18-2. testlog.sh

#!/bin/sh
#
#    testlog.sh -- a script to test the syslog facility to ensure that
#                  messages, at various levels, are being forwarded
#                  to the correct file(s)
#
# Set Behavior
FACILITY=local7
LOGGER="/usr/bin/logger"
# 
$LOGGER -p $FACILITY.emerg   "This meassage was sent to $FACILITY.emerg (0)"
$LOGGER -p $FACILITY.alert   "This meassage was sent to $FACILITY.alert (1)"
$LOGGER -p $FACILITY.crit    "This meassage was sent to $FACILITY.crit (2)"
$LOGGER -p $FACILITY.err     "This meassage was sent to $FACILITY.err (3)"
$LOGGER -p $FACILITY.warning "This meassage was sent to $FACILITY.warning (4)"
$LOGGER -p $FACILITY.notice  "This meassage was sent to $FACILITY.notice (5)"
$LOGGER -p $FACILITY.info    "This meassage was sent to $FACILITY.info (6)"
$LOGGER -p $FACILITY.debug   "This meassage was sent to $FACILITY.debug (7)"
