REST Resource: projects.metricDescriptors

Resource: MetricDescriptor

Defines a metric type and its schema. Once a metric descriptor is created, deleting or altering it stops data collection and makes the metric type's existing data unusable.

Fields
name

string

The resource name of the metric descriptor.

type

string

The metric type, including its DNS name prefix. The type is not URL-encoded. All user-defined custom metric types have the DNS name custom.googleapis.com. Metric types should use a natural hierarchical grouping. For example:

"custom.googleapis.com/invoice/paid/amount"
"appengine.googleapis.com/http/server/response_latencies"

labels[]

object(LabelDescriptor)

The set of labels that can be used to describe a specific instance of this metric type. For example, the appengine.googleapis.com/http/server/response_latencies metric type has a label for the HTTP response code, response_code, so you can look at latencies for successful responses or just for responses that failed.

metricKind

enum(MetricKind)

Whether the metric records instantaneous values, changes to a value, etc. Some combinations of metricKind and valueType might not be supported.

valueType

enum(ValueType)

Whether the measurement is an integer, a floating-point number, etc. Some combinations of metricKind and valueType might not be supported.

unit

string

Optional. The unit in which the metric value is reported. For example, kBy/s means kilobytes/sec, and 1 is the dimensionless unit. The supported units are a subset of The Unified Code for Units of Measure standard.

This field is part of the metric's documentation, but it is ignored by Stackdriver.

description

string

A detailed description of the metric, which can be used in documentation.

displayName

string

A concise name for the metric, which can be displayed in user interfaces. Use sentence case without an ending period, for example "Request count". This field is optional but it is recommended to be set for any metrics associated with user-visible concepts, such as Quota.

MetricKind

The kind of measurement. It describes how the data is reported.

Enums
METRIC_KIND_UNSPECIFIED Do not use this default value.
GAUGE An instantaneous measurement of a value.
DELTA The change in a value during a time interval.
CUMULATIVE A value accumulated over a time interval. Cumulative measurements in a time series should have the same start time and increasing end times, until an event resets the cumulative value to zero and sets a new start time for the following points.

ValueType

The value type of a metric.

Enums
VALUE_TYPE_UNSPECIFIED Do not use this default value.
BOOL The value is a boolean. This value type can be used only if the metric kind is GAUGE.
INT64 The value is a signed 64-bit integer.
DOUBLE The value is a double precision floating point number.
STRING The value is a text string. This value type can be used only if the metric kind is GAUGE.
DISTRIBUTION The value is a Distribution.
MONEY The value is money.

Methods

create

Creates a new metric descriptor.

delete
