Error when using to_syslog_ietf() function in config for Ubuntu 18.04

#1 abajosh 2 years ago

The following config file works in Ubuntu 14.04, but throws an error when used on an 18.04 server. Am I using the to_syslog_ietf() function incorrectly?

Hi Josh,

You are experiencing an error because you did not import the Syslog extension.

<Extension _syslog>
    Module  xm_syslog
</Extension>

I hope this helps
