juju debug-log will show all of the consolidated logs of all the Juju agents running on each node of the cluster. This can be useful for finding out why a specific node hasn’t deployed or is in an error state. These agent logs are located in
/var/lib/juju/agents on every node.
See the Juju documentation for more information.
Log verbosity in Juju is set at the model level. You can adjust it at any time:
juju add-model k8s-development --config logging-config='<root>=DEBUG;unit=DEBUG'
juju config-model k8s-production --config logging-config='<root>=ERROR;unit=ERROR'
In addition, the jujud daemon is started in debug mode by default on all controllers. To remove that behavior edit
/var/lib/juju/init/jujud-machine-0/exec-start.sh on the controller node and comment the
It then contains:
#!/usr/bin/env bash # Set up logging. touch '/var/log/juju/machine-0.log' chown syslog:syslog '/var/log/juju/machine-0.log' chmod 0600 '/var/log/juju/machine-0.log' exec >> '/var/log/juju/machine-0.log' exec 2>&1 # Run the script. '/var/lib/juju/tools/machine-0/jujud' machine --data-dir '/var/lib/juju' --machine-id 0 # --debug
Then restart the service with:
sudo systemctl restart jujud-machine-0.service
