Kibana error after upgrade to version 8.0 [config validation of [logging].dest]: definition for this key is missing]

Hi,

I had successfully upgraded to version 8.0 on ELK , while the rest of the stack works , kibana has failed to start citing

dev-elk-app01 kibana[19018]:  FATAL  Error: [config validation of [logging].dest]: definition for this key is missing

i understand from a bit of googling that logging.dest is no longer supported on 8.0 , however my yml configuration has no entry for logging.dest .

Could someone help out ?

here's the full error:

found the reason , it seems my systemd unit was still referring to logging.dest , removing it seemed to have worked and moved on to the next problem

ExecStart=/usr/share/kibana/bin/kibana --logging.dest="/var/log/kibana/kibana.log" --pid.file="/run/kibana/kibana.pid" --deprecation.skip_deprecated_settings[0]="logging.dest"


new error

How did you manage to remove it ?

Hey,

I had the same issue.

To fix it on Ubuntu/Debian:
Open /etc/systemd/system/kibana.service in your favorite editor.
Find the ExecStart line and remove the logging.dest setting.

Before:
ExecStart=/usr/share/kibana/bin/kibana --logging.dest="/var/log/kibana/kibana.log" --pid.file="/run/kibana/kibana.pid" --deprecation.skip_deprecated_settings[0]="logging.dest"

After:
ExecStart=/usr/share/kibana/bin/kibana --pid.file="/run/kibana/kibana.pid" --deprecation.skip_deprecated_settings[0]="logging.dest"

It looks like the command line argument is deprecated and it's expected that setting will be in the /etc/kibana/kibana.yml.

If you want to have kibana logs in /var/log/kibana/kibana.log, make sure your /etc/kibana/kibana.yml has this in it:

logging:
  appenders:
    file:
      type: file
      fileName: /var/log/kibana/kibana.log
      layout:
        type: json
  root:
    appenders:
