filebeat version 7.4.2 with elasticsearch (same version)
and the system module.
How can I filter the the log messages for facility and priority fields?
Can I tweak/configure the filebeat system module to extract them?
I turned this fields on in rsyslog.conf with a simple filter like so:
$template TraditionalFormatWithPRI,"%pri-text%: %timegenerated% %HOSTNAME% %syslogtag%%msg:::drop-last-lf%\n"
resulting in loglines lookinig like this:
daemon.info: Nov 26 20:15:02 myhost systemd: Started Hostname Service.
but they are just cleanly filtered out when I look at the line in kibana.
I used to think it's quite helpful to have a filter at least for the priority!
Any way to achieve this with the system module?
