The debug configuration option controls the amount of logs produced by the modem-manager snap. It is useful for collecting information required to either report a bug or investigate a modem-manager failure.
It is disabled by default and has to be explicitly turned on for usage.
Note that the debug logs may contain sensitive information.
Enable Debug
The modem-manager snap provides a single configuration option which can be used to turn the debug feature either on or off:
- debug.enable
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 MM daemon.
Example: Enable debug feature
$ snap set modem-manager debug.enable=true
Example: Disable debug feature.
$ snap set modem-manager debug.enable=false
Viewing logs
The debug information, when enabled, will be available in the journal and can be viewed with:
$ journalctl --no-pager -u snap.modem-manager.modemmanager.service
