Each registered measure needs -to be unique by name. Measures also have a description and a unit. - -Libraries can define and export measures. Application authors can then -create views and collect and break down measures by the tags they are -interested in. - -# Recording measurements - -Measurement is a data point to be collected for a measure. For example, -for a latency (ms) measure, 100 is a measurement that represents a 100ms -latency event. Measurements are created from measures with -the current context. Tags from the current context are recorded with the -measurements if they are any. - -Recorded measurements are dropped immediately if no views are registered for them. -There is usually no need to conditionally enable and disable -recording to reduce cost. Recording of measurements is cheap. - -Libraries can always record measurements, and applications can later decide -on which measurements they want to collect by registering views. This allows -libraries to turn on the instrumentation by default. - -# Exemplars - -For a given recorded measurement, the associated exemplar is a diagnostic map -that gives more information about the measurement. - -When aggregated using a Distribution aggregation, an exemplar is kept for each -bucket in the Distribution. This allows you to easily find an example of a -measurement that fell into each bucket. - -For example, if you also use the OpenCensus trace package and you -record a measurement with a context that contains a sampled trace span, -then the trace span will be added to the exemplar associated with the measurement. - -When exported to a supporting back end, you should be able to easily navigate -to example traces that fell into each bucket in the Distribution. -*/ -package stats // import "go.opencensus.io/stats" |
