Rsyslog 8 dynafile with a template

  • 772

I'm trying to setup rsyslog to use the template RSYSLOG_TraditionalFileFormat as the default action template, but for some specific messages i need to use another template. In both cases i need dynaFile.

I'm trying to achieve that with:

#$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

$template dynatemplate, "/var/log/%HOSTNAME%/%PROGRAMNAME%.log"
$template dynatemplate2, "/var/log/%HOSTNAME%/%hostname%_%fromhost-ip%_%syslogtag%.log"

:msg, contains, "sometext" ?dynatemplate2;RSYSLOG_SyslogProtocol23Format
& ~

*.* ?dynatemplate

Would the above be considered the correct way?

Also since I'm using rsyslog 8.24 how could it be done using the expression syntax?

  1. It looks ok to me. Here's a RainerScript version, untested. I don't think the last action() needs a *.* in front of it as that is the default, but do add it if nothing is matched.

    template(name="dynatemplate" type="string" 
  string="/var/log/%HOSTNAME%/%PROGRAMNAME%.log")
template(name="dynatemplate2" type="string"
  string="/var/log/%HOSTNAME%/%hostname%_%fromhost-ip%_%syslogtag%.log")

if ($msg contains "sometext") then {
  action(type="omfile" dynaFile="dynatemplate2" template="RSYSLOG_SyslogProtocol23Format")
  stop
}
action(type="omfile" dynaFile="dynatemplate")
