Getting the serial port output
You can get the output from a VM serial port and use it, e.g., for troubleshooting.
To access the output data, you need the compute.operator or viewer role.
- Select the folder the VM belongs to.
- Navigate to Compute Cloud.
- Click the line with the VM in question.
- Go to the Serial port tab.
- To use the CTRL + F shortcut to search, enable Raw mode in the top-right corner.
The folder used by default is the one specified when creating the CLI profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also specify a different folder for any command using --folder-name or --folder-id. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.

See the description of the command for getting the serial port output:
yc compute instance get-serial-port-output --help -
Select a VM, e.g.,
first-instance:yc compute instance listResult:
+----------------------+-----------------+---------------+---------+----------------------+ | ID | NAME | ZONE ID | STATUS | DESCRIPTION | +----------------------+-----------------+---------------+---------+----------------------+ | fhm0b28lgfp4******** | first-instance | ru-central1-a | RUNNING | my first vm via CLI | | fhm9gk85nj7g******** | second-instance | ru-central1-a | RUNNING | my second vm via CLI | +----------------------+-----------------+---------------+---------+----------------------+ -
Get its serial port output. Since the serial port output is usually lengthy, we recommend writing it to a file:
yc compute instance get-serial-port-output first-instance > output.txt
To get the serial port output, use the getSerialPortOutput REST API method for the Instance resource or the InstanceService/GetSerialPortOutput gRPC API call.
