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"
- `unit`**Type**: `STRING`**Provider name**: `unit`**Description**: 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](https://unitsofmeasure.org/ucum.html) standard: **Basic units (UNIT)** * `bit` bit * `By` byte * `s` second * `min` minute * `h` hour * `d` day * `1` dimensionless **Prefixes (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) **Grammar** The 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").
- `value_type`**Type**: `STRING`**Provider name**: `valueType`**Description**: Whether the measurement is an integer, a floating-point number, etc. Some combinations of `metric_kind` and `value_type` might not be supported.**Possible values**:
  - `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.

    - `PRELAUNCH` - Prelaunch features are hidden from users and are only visible internally.
    - `EARLY_ACCESS` - Early Access features are limited to a closed group of testers. To use these features, you must sign up in advance and sign a Trusted Tester agreement (which includes confidentiality provisions). These features may be unstable, changed in backward-incompatible ways, and are not guaranteed to be released.
    - `ALPHA` - Alpha is a limited availability test for releases before they are cleared for widespread use. By Alpha, all significant design issues are resolved and we are in the process of verifying functionality. Alpha customers need to apply for access, agree to applicable terms, and have their projects allowlisted. Alpha releases don't have to be feature complete, no SLAs are provided, and there are no technical support obligations, but they will be far enough along that customers can actually use them in test environments or for limited-use tests – just like they would in normal production cases.
    - `BETA` - Beta is the point at which we are ready to open a release for any customer to use. There are no SLA or technical support obligations in a Beta release. Products will be complete from a feature perspective, but may have some open outstanding issues. Beta releases are suitable for limited production use cases.
    - `GA` - GA features are open to all developers and are considered stable and fully qualified for production use.
    - `DEPRECATED` - Deprecated features are scheduled to be shut down and removed. For more information, see the 'Deprecation Policy' section of our [Terms of Service](https://cloud.google.com/terms/) and the [Google Cloud Platform Subject to the Deprecation Policy](https://cloud.google.com/terms/deprecation) documentation.

## `usage`{% #usage %}

**Type**: `STRUCT`**Provider name**: `usage`**Description**: Configuration controlling usage of this service.

- `producer_notification_channel`**Type**: `STRING`**Provider name**: `producerNotificationChannel`**Description**: The full resource name of a channel used for sending notifications to the service producer. Google Service Management currently only supports [Google Cloud Pub/Sub](https://cloud.google.com/pubsub) as a notification channel. To use Google Cloud Pub/Sub as the channel, this must be the name of a Cloud Pub/Sub topic that uses the Cloud Pub/Sub topic name format documented in [https://cloud.google.com/pubsub/docs/overview](https://cloud.google.com/pubsub/docs/overview).
- `requirements`**Type**: `UNORDERED_LIST_STRING`**Provider name**: `requirements`**Description**: Requirements that must be satisfied before a consumer project can use the service. Each requirement is of the form /; for example 'serviceusage.googleapis.com/billing-enabled'. For Google APIs, a Terms of Service requirement must be included here. Google Cloud APIs must include "serviceusage.googleapis.com/tos/cloud". Other Google APIs should include "serviceusage.googleapis.com/tos/universal". Additional ToS can be included based on the business needs.
- `rules`**Type**: `UNORDERED_LIST_STRUCT`**Provider name**: `rules`**Description**: A list of usage rules that apply to individual API methods. **NOTE:** All service configuration rules follow "last one wins" order.
  - `allow_unregistered_calls`**Type**: `BOOLEAN`**Provider name**: `allowUnregisteredCalls`**Description**: Use this rule to configure unregistered calls for the service. Unregistered calls are calls that do not contain consumer project identity. (Example: calls that do not contain an API key). WARNING: By default, API methods do not allow unregistered calls, and each method call must be identified by a consumer project identity.
  - `selector`**Type**: `STRING`**Provider name**: `selector`**Description**: Selects the methods to which this rule applies. Use '*' to indicate all methods in all APIs. Refer to selector for syntax details.
  - `skip_service_control`**Type**: `BOOLEAN`**Provider name**: `skipServiceControl`**Description**: If true, the selected method should skip service control and the control plane features, such as quota and billing, will not be available. This flag is used by Google Cloud Endpoints to bypass checks for internal methods, such as service health check methods.
