Overview

Package metric is a generated protocol buffer package.

The `metric` template is designed to let you describe runtime metric to dispatch to monitoring backends.

Example config:

```yaml apiVersion: "config.istio.io/v1alpha2" kind: metric metadata: 

name: requestsize
namespace: istio-system

spec: 

value: request.size | 0
dimensions:
  source_version: source.labels["version"] | "unknown"
  destination_service: destination.service.host | "unknown"
  destination_version: destination.labels["version"] | "unknown"
  response_code: response.code | 200
monitored_resource_type: '"UNSPECIFIED"'

```

The `metric` template represents a single piece of data to report.

When writing the configuration, the value for the fields associated with this template can either be a literal or an [expression](https://istio.io/docs/reference//config/policy-and-telemetry/expression-language/). Please note that if the datatype of a field is not istio.policy.v1beta1.Value, then the expression's [inferred type](https://istio.io/docs/reference//config/policy-and-telemetry/expression-language/#type-checking) must match the datatype of the field.

type HandleMetricRequest 

type HandleMetricRequest struct {
	// 'metric' instances.
	Instances []*InstanceMsg `protobuf:"bytes,1,rep,name=instances" json:"instances,omitempty"`
	// Adapter specific handler configuration.
	//
	// Note: Backends can also implement [InfrastructureBackend][https://istio.io/docs/reference/config/mixer/istio.mixer.adapter.model.v1beta1.html#InfrastructureBackend]
	// service and therefore opt to receive handler configuration during session creation through [InfrastructureBackend.CreateSession][TODO: Link to this fragment]
	// call. In that case, adapter_config will have type_url as 'google.protobuf.Any.type_url' and would contain string

type HandleMetricServiceClient interface {
	// HandleMetric is called by Mixer at request-time to deliver 'metric' instances to the backend.
	HandleMetric(ctx context.Context, in *HandleMetricRequest, opts ...grpc.CallOption) (*istio_mixer_adapter_model_v1beta11.ReportResult, error)

type HandleMetricServiceServer 

type HandleMetricServiceServer interface {

	HandleMetric(context.Context, *HandleMetricRequest) (*istio_mixer_adapter_model_v1beta11.ReportResult, error)

type Handler 

type Handler interface {
	adapter.Handler

	// HandleMetric is called by Mixer at request time to deliver instances to
	// to an adapter.
	HandleMetric(context.Context, []*Instance) error
}

Handler must be implemented by adapter code if it wants to process data associated with the 'metric' template.

Mixer uses this interface to call into the adapter at request time in order to dispatch created instances to the adapter. Adapters take the incoming instances and do what they need to achieve their primary function.

The name of each instance can be used as a key into the Type map supplied to the adapter at configuration time via the method 'SetMetricTypes'. These Type associated with an instance describes the shape of the instance

type HandlerBuilder 

type HandlerBuilder interface {
	adapter.HandlerBuilder

	// SetMetricTypes is invoked by Mixer to pass the template-specific Type information for instances that an adapter
	// may receive at runtime. The type information describes the shape of the instance.
	SetMetricTypes(map[string]*Type)
}

HandlerBuilder must be implemented by adapters if they want to process data associated with the 'metric' template.

Mixer uses this interface to call into the adapter at configuration time to configure it with adapter-specific configuration as well as all template-specific type information.

type Instance 

type Instance struct {
	// Name of the instance as specified in configuration.
	Name string

	// The value being reported.
	Value interface{}

	// The unique identity of the particular metric to report.
	Dimensions map[string]interface{}

	// Optional. An expression to compute the type of the monitored resource this metric is being reported on.
	// If the metric backend supports monitored resources, these fields are used to populate that resource. Otherwise
	// these fields will be ignored by the adapter.
	MonitoredResourceType string

	// Optional. A set of expressions that will form the dimensions of the monitored resource this metric is being reported on.
	// If the metric backend supports monitored resources, these fields are used to populate that resource. Otherwise
	// these fields will be ignored by the adapter.
	MonitoredResourceDimensions map[string]interface{}
}

Instance is constructed by Mixer for the 'metric' template.

The `metric` template represents a single piece of data to report.

When writing the configuration, the value for the fields associated with this template can either be a literal or an [expression](https://istio.io/docs/reference//config/policy-and-telemetry/expression-language/). Please note that if the datatype of a field is not istio.policy.v1beta1.Value, then the expression's [inferred type](https://istio.io/docs/reference//config/policy-and-telemetry/expression-language/#type-checking) must match the datatype of the field.

type InstanceMsg 

type InstanceMsg struct {
	// Name of the instance as specified in configuration.
	Name string `protobuf:"bytes,72295727,opt,name=name,proto3" json:"name,omitempty"`
	// The value being reported.
	Value *istio_policy_v1beta11.Value `protobuf:"bytes,1,opt,name=value" json:"value,omitempty"`
	// The unique identity of the particular metric to report.
	Dimensions map[string]*istio_policy_v1beta11.Value `` /* 147-byte string literal not displayed */
	// Optional. An expression to compute the type of the monitored resource this metric is being reported on.
	// If the metric backend supports monitored resources, these fields are used to populate that resource. Otherwise
	// these fields will be ignored by the adapter.
	MonitoredResourceType string `` /* 126-byte string literal not displayed */
	// Optional. A set of expressions that will form the dimensions of the monitored resource this metric is being reported on.
	// If the metric backend supports monitored resources, these fields are used to populate that resource. Otherwise
	// these fields will be ignored by the adapter.
	MonitoredResourceDimensions map[string]*istio_policy_v1beta11.Value `` /* 218-byte string literal not displayed */
}
