Reference documentation and code samples for the Google API Common Protos Client class 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.

__construct
Constructor.
data
array
Optional. Data for populating the Message object.
↳ 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 metric types have the DNS name custom.googleapis.com
or external.googleapis.com
. Metric types should use a natural hierarchical grouping. For example: "custom.googleapis.com/invoice/paid/amount" "external.googleapis.com/prometheus/up" "appengine.googleapis.com/http/server/response_latencies"
↳ labels
array< 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.
↳ metric_kind
int
Whether the metric records instantaneous values, changes to a value, etc. Some combinations of metric_kind
and value_type
might not be supported.
↳ value_type
int
Whether the measurement is an integer, a floating-point number, etc. Some combinations of metric_kind
and value_type
might not be supported.
↳ unit
string
The units in which the metric value is reported. It is only applicable if the value_type
is INT64
, DOUBLE
, or DISTRIBUTION
. The unit
defines the representation of the stored metric values. Different systems might scale the values to be more easily displayed (so a value of 0.02kBy
might
be displayed as 20By
, and a value of 3523kBy
might
be displayed as 3.5MBy
). However, if the unit
is kBy
, then the value of the metric is always in thousands of bytes, no matter how it might be displayed. If you want a custom metric to record the exact number of CPU-seconds used by a job, you can create an INT64 CUMULATIVE
metric whose unit
is s{CPU}
(or equivalently 1s{CPU}
or just s
). If the job uses 12,005 CPU-seconds, then the value is written as 12005
. Alternatively, if you want a custom metric to record data in a more granular way, you can create a DOUBLE CUMULATIVE
metric whose unit
is ks{CPU}
, and then write the value 12.005
(which is 12005/1000
), or use Kis{CPU}
and write 11.723
(which is 12005/1024
). The supported units are a subset of The Unified Code for Units of Measure

represents a unitary dimensionless unit
of 1, such as in 1/s
. It is typically used when none of the basic units are appropriate. For example, "new users per day" can be represented as 1/d
or {new-users}/d
(and a metric value 5
would mean "5 new users). Alternatively, "thousands of page views per day" would be represented as 1000/d
or k1/d
or k{page_views}/d
(and a metric value of 5.3
would mean "5300 page views per day"). * %
represents dimensionless value of 1/100, and annotates values giving a percentage (so the metric values are typically in the range of 0..100, and a metric value 3
means "3 percent"). * 10^2.%
indicates a metric contains a ratio, typically in the range 0..1, that will be multiplied by 100 and displayed as a percentage (so a metric value 0.03
means "3 percent").
