# Cloud Monitoring API . timeseriesDescriptors

## Instance Methods

List the descriptors of the time series that match the metric and labels values and that have data points in the interval. Large responses are paginated; use the nextPageToken returned in the response to request subsequent pages of results by setting the pageToken query parameter to the value of the nextPageToken.

Retrieves the next page of results.

### Method Details

`list(project, metric, youngest, count=None, timespan=None, labels=None, pageToken=None, oldest=None)`

    List the descriptors of the time series that match the metric and labels values and that have data points in the interval. Large responses are paginated; use the nextPageToken returned in the response to request subsequent pages of results by setting the pageToken query parameter to the value of the nextPageToken.

    Args:
      project: string, The project ID to which this time series belongs. The value can be the numeric project ID or string-based project name. (required)
      metric: string, Metric names are protocol-free URLs as listed in the Supported Metrics page. For example, compute.googleapis.com/instance/disk/read_ops_count. (required)
      youngest: string, End of the time interval (inclusive), which is expressed as an RFC 3339 timestamp. (required)
      count: integer, Maximum number of time series descriptors per page. Used for pagination. If not specified, count = 100.
      timespan: string, Length of the time interval to query, which is an alternative way to declare the interval: (youngest - timespan, youngest]. The timespan and oldest parameters should not be used together. Units:
    - s: second
    - m: minute
    - h: hour
    - d: day
    - w: week  Examples: 2s, 3m, 4w. Only one unit is allowed, for example: 2w3d is not allowed; you should use 17d instead.

    If neither oldest nor timespan is specified, the default time interval will be (youngest - 4 hours, youngest].
      labels: string, A collection of labels for the matching time series, which are represented as:
    - key==value: key equals the value
    - key=~value: key regex matches the value
    - key!=value: key does not equal the value
    - key!~value: key regex does not match the value  For example, to list all of the time series descriptors for the region us-central1, you could specify:
    label=cloud.googleapis.com%2Flocation=~us-central1.* (repeated)
      pageToken: string, The pagination token, which is used to page through large result sets. Set this value to the value of the nextPageToken to retrieve the next page of results.
      oldest: string, Start of the time interval (exclusive), which is expressed as an RFC 3339 timestamp. If neither oldest nor timespan is specified, the default time interval will be (youngest - 4 hours, youngest]

    Returns:
      An object of the form:

        { # The response of cloudmonitoring.timeseriesDescriptors.list
        "nextPageToken": "A String", # Pagination token. If present, indicates that additional results are available for retrieval. To access the results past the pagination limit, set this value to the pageToken query parameter.
        "youngest": "A String", # The youngest timestamp of the interval of this query, as an RFC 3339 string.
        "kind": "cloudmonitoring#listTimeseriesDescriptorsResponse", # Identifies what kind of resource this is. Value: the fixed string "cloudmonitoring#listTimeseriesDescriptorsResponse".
        "oldest": "A String", # The oldest timestamp of the interval of this query, as an RFC 3339 string.
        "timeseries": [ # The returned time series descriptors.
          { # TimeseriesDescriptor identifies a single time series.
            "project": "A String", # The Developers Console project number to which this time series belongs.
            "metric": "A String", # The name of the metric.
            "labels": { # The label's name.
              "a_key": "A String", # The label's name.
            },
          },
        ],
      }

`list_next(previous_request, previous_response)`

    Retrieves the next page of results.

    Args:
      previous_request: The request for the previous page. (required)
      previous_response: The response from the request for the previous page. (required)

    Returns:
      A request object that you can call 'execute()' on to request the next
      page. Returns None if there are no more items in the collection.
