### Method Details

`list(projectId, jobId, startTime=None, pageSize=None, x__xgafv=None, pageToken=None, location=None, minimumImportance=None, endTime=None)`

    Request the job status.

    Args:
      projectId: string, A project id. (required)
      jobId: string, The job to get messages about. (required)
      startTime: string, If specified, return only messages with timestamps >= start_time.
    The default is the job creation time (i.e. beginning of messages).
      pageSize: integer, If specified, determines the maximum number of messages to
    return.  If unspecified, the service may choose an appropriate
    default, or may return an arbitrarily large number of results.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format
      pageToken: string, If supplied, this should be the value of next_page_token returned
    by an earlier call. This will cause the next page of results to
    be returned.
      location: string, The location which contains the job specified by job_id.
      minimumImportance: string, Filter to only get messages with importance >= level
      endTime: string, Return only messages with timestamps < end_time. The default is now
    (i.e. return up to the latest messages available).

    Returns:
      An object of the form:
