getSerialPortOutput method

Future<SerialPortOutput> getSerialPortOutput(
  1. String project,
  2. String zone,
  3. String instance, {
  4. int? port,
  5. String? start_1,
  6. String? $fields,
})

Returns the last 1 MB of serial port output from the specified instance.

Request parameters:

project - Project ID for this request. Value must have pattern (?:(?:\[-a-z0-9\]{1,63}\.)*(?:\[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?):)?(?:\[0-9\]{1,19}|(?:\[a-z0-9\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?)).

zone - The name of the zone for this request. Value must have pattern \[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?.

instance - Name of the instance for this request. Value must have pattern \[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?|\[1-9\]\[0-9\]{0,19}.

port - Specifies which COM or serial port to retrieve data from. Value must be between "1" and "4".

start_1 - Specifies the starting byte position of the output to return. To start with the first byte of output to the specified port, omit this field or set it to 0. If the output for that byte position is available, this field matches the start parameter sent with the request. If the amount of serial console output exceeds the size of the buffer (1 MB), the oldest output is discarded and is no longer available. If the requested start position refers to discarded output, the start position is adjusted to the oldest output still available, and the adjusted start position is returned as the start property value. You can also provide a negative start position, which translates to the most recent number of bytes written to the serial port. For example, -3 is interpreted as the most recent 3 bytes written to the serial console.

$fields - Selector specifying which fields to include in a partial response.

Completes with a SerialPortOutput.

Completes with a commons.ApiRequestError if the API endpoint returned an error.

If the used http.Client completes with an error when making a REST call, this method will complete with the same error.
