Notes on the output format of the syslog messages

If you output the control characters such as linefeed and tabs (ASCII code 0-31, 127) to syslog with Red Hat Enterprise Linux Server 6, the results will differ from the output results of Red Hat Enterprise Linux 5 with the default settings. With Red Hat Enterprise Linux Server 6, convert the control characters to #number (number expresses the character code with a 3-digit octal numeral) to output the characters.

The procedure for changing the output to the one similar to Red Hat Enterprise Linux 5 is as follows:

1. Update rsyslog to version rsyslog-4.6.2-3.el6_1.4 or later.
2. Set the following options in /etc/rsyslog.conf:
   $EscapeControlCharactersOnReceive off
   $ActionFileDefaultTemplate RSYSLOG_SysklogdFileFormat
   $SpaceLFOnReceive on
   $DropTrailingLFOnReception off
   
3. Execute service rsyslog restart to restart rsyslog.
