How to view the instance logs
You can view the Anbox and the Android system logs while an instance is running, or check the collected logs if an instance fails.
AMS does not support runtime log collection. Logs are currently only being collected from an instance that failed to start or had an error at runtime.
While an instance is running, you can use the
amc command to access both the Anbox and the Android system logs. The following command shows the system log:
amc logs -t <log type>
<log type>, specify either
anbox for the Anbox system log or
android for the Android one. If you don’t specify the log type, the Anbox system log is displayed by default.
To follow the log and get automatic updates for new entries, add the
amc logs -t anbox -f
This will show the logs and update the output whenever new entries are added.
If an instance fails to start or a runtime error occurs, AMS collects relevant log files from the instance and makes them available for inspection.
Available logs can be listed with the
amc show <instance_id> command:
id: bh03th0j1qm6416q0v30 name: ams-bh03th0j1qm6416q0v30 status: error node: lxd0 created_at: 1970-01-01T00:00:00Z application: id: bh03tgoj1qm6416q0v2g network: address: 192.168.100.2 public_address: 10.226.4.63 services:  stored_logs: - container.log - system.log - android.log error_message: 'Failed to install application com.canonical.candy: exit status 1'
The instance in this example failed to install the application as indicated by the
error_message field. There are three log files being stored which can be shown with the
amc show-log command (for example,
amc show-log bh03th0j1qm6416q0v30 system.log):
