rsyslog

Installation

apt-get install rsyslog

The configuration file is at

/etc/rsyslog.conf

Basic syntax

To define log format.

$template <format name>
, "<format string>"

To filter and select destination.

if <filter logic> then <destination>;<format name>

For the above, it must be in one line, or with line separator "\".

Example :

$EscapeControlCharactersOnReceive off

If you see your log happened to have the messages claimed to be repeated as below image :


The default configuration file must have this $RepeatedMsgReduction is turned on. Comment out the line with #.

# $RepeatedMsgReduction on
