You can analyze activity by viewing the serial port output and instance lifecycle events of an instance.
All lifecycle and system events that affect the state of a VM instance are captured in the Cloud Audit Log. Lifecycle events include:
- Deleting an instance
- Creating an instance
- Stopping an instance
- Resetting an instance
- Suspending an instance
- Resuming an instance
System events include:
- Automatic restart of an instance
- Guest OS shutdown
- Host error
- Instance migration due to host maintenance
- Instance termination due to host maintenance
To view these events for a selected instance, zone, or entire project, do the following:
-
In the Project Explorer tool window, right-click a VM instance and select Show event log.
It might take several seconds for the event log data to load.
-
In the Event Log window, you can browse the events in reverse chronological order
-
Optionally, double-click an event to view details in the Logs viewer
To analyze activity of the operating system running on the VM instance, you can inspect the VM instance's serial ports:
- Serial port 1 (COM1) contains boot output as well as diagnostic information emitted by agents
- Serial port 3 (COM3) is commonly used by Windows Setup when performing in-place upgrades of Windows Server
- Serial port 4 (COM4) is used by agents to communicate with tools, for example when creating a Windows user account
To view Serial port 1 (COM1) if an instance, do the following:
-
In the Project Explorer tool window, right-click a VM instance and select Connect:
-
The Serial log window shows the serial port output:
To view other serial ports, select View > Serial port output in the main menu and select the serial port to view.
