Introduction

In case you ever need to view important system messages, it is a wise idea to install a system logger. System loggers create a log in ‘’/var/log’’ Several different loggers exist. Listed below are some of the more commonly used loggers: metalog syslog-ng

Installation and adding to runlevel

To install a logger, run the following command:

#  emerge --ask metalog

These are the packages that would be merged, in order:

After installing the logger, we have to add its initialization script to RC’s default runlevel. The default runlevel, defined at /etc/runlevels/default, contains symbolic links to all system initialization scripts that are run by default. To add the logger to the runlevel and then start the logger, run the following:

#  rc-update add metalog default
#  rc
 * Starting metalog ...

Stopping the service

If, for whatever reason, you need to stop a service manually, you can run its initialization script directly from /etc/init.d:

# /etc/init.d/metalog stop
 * Stopping metalog ...
