Debug is a feature that controls the amount of logs produced by the network-manager snap. It is useful for collecting information required to either report a bug or investigate a network-manager failure (if happens).
It is disabled by default and has to be explicitly turned on for usage.
Note that the debug logs may contain sensitive information.
The network-manager snap provides a single configuration option which can be used to turn the debug feature either on or off:
The option takes a boolean value. The meaning of the possible values are:
- true: Enable logging debug information
- false (default): Disable logging debug information
Changing the debug configuration option has immediate effect and also affects future executions of the NM daemon.
Example: Enable debug feature
$ snap set network-manager debug.enable=true
Example: Disable debug feature.
$ snap set network-manager debug.enable=false
The debug information, when enabled, will be available in the journal and can be viewed with:
$ journalctl --no-pager -l -u snap.network-manager.networkmanager.service
