}

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.The following are specific rules for service defined Monitoring metric descriptors: type, metric_kind, value_type, description, display_name, launch_stage fields are all required. The unit field must be specified if the value_type is any of DOUBLE, INT64, DISTRIBUTION. Maximum of default 500 metric descriptors per service is allowed. Maximum of default 10 labels per metric descriptor is allowed.The default maximum limit can be overridden. Please follow https://cloud.google.com/monitoring/quotas

This type is not used in any activity, and only used as part of another schema.

Fields

display_name: Option<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.

description: Option<String>

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

metric_kind: Option<String>

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: Option<String>

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

labels: Option<Vec<LabelDescriptor>>

The set of labels that can be used to describe a specific instance of this metric type.The label key name must follow: Only upper and lower-case letters, digits and underscores (_) are allowed. Label name must start with a letter or digit. The maximum length of a label name is 100 characters.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.

launch_stage: Option<String>

Optional. The launch stage of the metric definition.

monitored_resource_types: Option<Vec<String>>

Read-only. If present, then a time series, which is identified partially by a metric type and a MonitoredResourceDescriptor, that is associated with this metric type can only be associated with one of the monitored resource types listed here.

metadata: Option<MetricDescriptorMetadata>

Optional. Metadata which can be used to guide usage of the metric.

type_: Option<String>

The metric type, including its DNS name prefix. The type is not URL-encoded.All service defined metrics must be prefixed with the service name, in the format of {service name}/{relative metric name}, such as cloudsql.googleapis.com/database/cpu/utilization. The relative metric name must follow: Only upper and lower-case letters, digits, '/' and underscores '_' are allowed. The maximum number of characters allowed for the relative_metric_name is 100.All user-defined metric types have the DNS name custom.googleapis.com, external.googleapis.com, or logging.googleapis.com/user/.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"

unit: Option<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 may 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 may 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 (http://unitsofmeasure.org/ucum.html) standard:Basic units (UNIT) bit bit By byte s second min minute h hour d day 1 dimensionlessPrefixes (PREFIX) k kilo (10^3) M mega (10^6) G giga (10^9) T tera (10^12) P peta (10^15) E exa (10^18) Z zetta (10^21) Y yotta (10^24) m milli (10^-3) u micro (10^-6) n nano (10^-9) p pico (10^-12) f femto (10^-15) a atto (10^-18) z zepto (10^-21) y yocto (10^-24) Ki kibi (2^10) Mi mebi (2^20) Gi gibi (2^30) Ti tebi (2^40) Pi pebi (2^50)GrammarThe grammar also includes these connectors: / division or ratio (as an infix operator). For examples, kBy/{email} or MiBy/10ms (although you should almost never have /s in a metric unit; rates should always be computed at query time from the underlying cumulative or delta value). . multiplication or composition (as an infix operator). For examples, GBy.d or k{watt}.h.The grammar for a unit is as follows: Expression = Component { "." Component } { "/" Component } ;

Component = ( [ PREFIX ] UNIT | "%" ) [ Annotation ] | Annotation | "1" ;

Annotation = "{" NAME "}" ; Notes: Annotation is just a comment if it follows a UNIT. If the annotation is used alone, then the unit is equivalent to 1. For examples, {request}/s == 1/s, By{transmitted}/s == By/s. NAME is a sequence of non-blank printable ASCII characters not containing { or }. 1 represents a unitary dimensionless unit (https://en.wikipedia.org/wiki/Dimensionless_quantity) 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").

name: Option<String>

The resource name of the metric descriptor.
