	Chapter 44. SYSLOG - The syslog protocol

Rsyslog is a SYSLOG daemon installed on Ubuntu. The purpose is to collect information and store them in /var/log/syslog file.

	Note
	Rsyslog daemon can store information using databases like MySQL, SQlite, SyBase. Search documentation on the Internet to know how to configure it.

44.7.1. Rsyslog configuration

Edit the file /etc/rsyslog.conf to enable rsyslog daemon to collect SYSLOG events from a client. There are two protocols available to collect information: UDP and TCP. Abilis uses UDP protocol; so edit /etc/rsyslog.conf (uncommenting lines):

$ModLoad imudp

$UDPServerRun 514

#  /etc/rsyslog.conf    Configuration file for rsyslog.
#
#                       For more information see
#                       /usr/share/doc/rsyslog-doc/html/rsyslog_conf.html
#
#  Default logging rules can be found in /etc/rsyslog.d/50-default.conf


#################
#### MODULES ####
#################

$ModLoad imuxsock # provides support for local system logging
$ModLoad imklog   # provides kernel logging support (previously done by rklogd)
#$ModLoad immark  # provides --MARK-- message capability

$KLogPath /proc/kmsg

# provides UDP syslog reception
$ModLoad imudp
$UDPServerRun 514

# provides TCP syslog reception
#$ModLoad imtcp
#$InputTCPServerRun 514

Type service rsyslog restart to restart SYSLOG daemon and apply the new configuration.

root@ubuntu-desktop:/var/log# service rsyslog restart
rsyslog start/running, process 2372
root@ubuntu-desktop:/var/log#

	Tip
	If Rsyslog isn't installed, type sudo apt-get install rsyslog to install it.

44.7.2. Syslog resource configuration

Add Syslog resource and then configure it so that RECEIVER1 parameter is equal to IP address of your SYSLOG server.
