Types

type AggregationTemporality added in v0.14.0 

type AggregationTemporality int32

AggregationTemporality defines how a metric aggregator reports aggregated values. It describes how those values relate to the time interval over which they are aggregated. 

const (
	// UNSPECIFIED is the default AggregationTemporality, it MUST not be used.
	AggregationTemporality_AGGREGATION_TEMPORALITY_UNSPECIFIED AggregationTemporality = 0
	// DELTA is an AggregationTemporality for a metric aggregator which reports
	// changes since last report time. Successive metrics contain aggregation of
	// values from continuous and non-overlapping intervals.
	//
	// The values for a DELTA metric are based only on the time interval
	// associated with one measurement cycle. There is no dependency on
	// previous measurements like is the case for CUMULATIVE metrics.
	//
	// For example, consider a system measuring the number of requests that
	// it receives and reports the sum of these requests every second as a
	// DELTA metric:
	//
	//   1. The system starts receiving at time=t_0.
	//   2. A request is received, the system measures 1 request.
	//   3. A request is received, the system measures 1 request.
	//   4. A request is received, the system measures 1 request.
	//   5. The 1 second collection cycle ends. A metric is exported for the
	//      number of requests received over the interval of time t_0 to
	//      t_0+1 with a value of 3.
	//   6. A request is received, the system measures 1 request.
	//   7. A request is received, the system measures 1 request.
	//   8. The 1 second collection cycle ends. A metric is exported for the
	//      number of requests received over the interval of time t_0+1 to
	//      t_0+2 with a value of 2.
	AggregationTemporality_AGGREGATION_TEMPORALITY_DELTA AggregationTemporality = 1
	// CUMULATIVE is an AggregationTemporality for a metic aggregator which
	// reports changes since a fixed start time. This means that current values
	// of a CUMULATIVE metric depend on all previous measurements since the
	// start time. Because of this, the sender is required to retain this state
	// in some form. If this state is lost or invalidated, the CUMULATIVE metric
	// values MUST be reset and a new fixed start time following the last
	// reported measurement time sent MUST be used.
	//
	// For example, consider a system measuring the number of requests that
	// it receives and reports the sum of these requests every second as a
	// CUMULATIVE metric:
	//
	//   1. The system starts receiving at time=t_0.
	//   2. A request is received, the system measures 1 request.
	//   3. A request is received, the system measures 1 request.
	//   4. A request is received, the system measures 1 request.
	//   5. The 1 second collection cycle ends. A metric is exported for the
	//      number of requests received over the interval of time t_0 to
	//      t_0+1 with a value of 3.
	//   6. A request is received, the system measures 1 request.
	//   7. A request is received, the system measures 1 request.
	//   8. The 1 second collection cycle ends. A metric is exported for the
	//      number of requests received over the interval of time t_0 to
	//      t_0+2 with a value of 5.
	//   9. The system experiences a fault and loses state.
	//   10. The system recovers and resumes receiving at time=t_1.
	//   11. A request is received, the system measures 1 request.
	//   12. The 1 second collection cycle ends. A metric is exported for the
	//      number of requests received over the interval of time t_1 to
	//      t_0+1 with a value of 1.
	//
	// Note: Even though, when reporting changes since last report time, using
	// CUMULATIVE is valid, it is not recommended. This may cause problems for
	// systems that do not use start_time to determine when the aggregation
	// value was reset (e.g. Prometheus).

type DoubleGauge added in v0.14.0 

type DoubleGauge struct {
	DataPoints           []*DoubleDataPoint `protobuf:"bytes,1,rep,name=data_points,json=dataPoints,proto3" json:"data_points,omitempty"`
	XXX_NoUnkeyedLiteral struct{}           `json:"-"`

	XXX_sizecache        int32              `json:"-"`
}

Gauge represents the type of a double scalar metric that always exports the "current value" for every data point. It should be used for an "unknown" aggregation.

A Gauge does not support different aggregation temporalities. Given the aggregation is unknown, points cannot be combined using the same aggregation, regardless of aggregation temporalities. Therefore, AggregationTemporality is not included. Consequently, this also means "StartTimeUnixNano" is ignored for all data points.

}

Gauge represents the type of a int scalar metric that always exports the "current value" for every data point. It should be used for an "unknown" aggregation.

A Gauge does not support different aggregation temporalities. Given the aggregation is unknown, points cannot be combined using the same aggregation, regardless of aggregation temporalities. Therefore, AggregationTemporality is not included. Consequently, this also means "StartTimeUnixNano" is ignored for all data points.

Defines a Metric which has one or more timeseries.

The data model and relation between entities is shown in the diagram below. Here, "DataPoint" is the term used to refer to any one of the specific data point value types, and "points" is the term used to refer to any one of the lists of points contained in the Metric.

  • Metric is composed of a metadata and data.

  • Metadata part contains a name, description, unit.

  • Data is one of the possible types (Gauge, Sum, Histogram, etc.).

  • DataPoint contains timestamps, labels, and one of the possible value type fields.

    Metric +------------+ |name | |description | |unit | +---------------------------+ |data |---> |Gauge, Sum, Histogram, ... | +------------+ +---------------------------+

    Data [One of Gauge, Sum, Histogram, ...] +-----------+ |... | // Metadata about the Data. |points |--+ +-----------+ | | +---------------------------+ | |DataPoint 1 | v |+------+------+ +------+ | +-----+ ||label |label |...|label | | | 1 |-->||value1|value2|...|valueN| | +-----+ |+------+------+ +------+ | | . | |+-----+ | | . | ||value| | | . | |+-----+ | | . | +---------------------------+ | . | . | . | . | . | . | . | +---------------------------+ | . | |DataPoint M | +-----+ |+------+------+ +------+ | | M |-->||label |label |...|label | | +-----+ ||value1|value2|...|valueN| | |+------+------+ +------+ | |+-----+ | ||value| | |+-----+ | +---------------------------+

All DataPoint types have three common fields:

  • Labels zero or more key-value pairs associated with the data point.
  • StartTimeUnixNano MUST be set to the start of the interval when the data's type includes an AggregationTemporality. This field is not set otherwise.
  • TimeUnixNano MUST be set to:
  • the moment when an aggregation is reported (independent of the aggregation temporality).
  • the instantaneous time of the event.
