Overview

Package stats provides primitives for recording metrics across the query path. Statistics are passed through the query context. To start a new query statistics context use: 

statsCtx, ctx := stats.NewContext(ctx)

Then you can update statistics by mutating data by using: 

statsCtx.Add...(1)

To get the statistic from the current context you can use: 

statsCtx := stats.FromContext(ctx)

Finally to get a snapshot of the current query statistic use 

statsCtx.Result(time.Since(start), queueTime, totalEntriesReturned)

Functions

func ConvertSecondsToNanoseconds 

func ConvertSecondsToNanoseconds(seconds float64) time.Duration

ConvertSecondsToNanoseconds converts time.Duration representation of seconds (float64) into time.Duration representation of nanoseconds (int64)

func JoinIndex 

func JoinIndex(ctx context.Context, index Index)

JoinIndex joins the index statistics in a concurrency-safe manner.

func JoinIngesters 

func JoinIngesters(ctx context.Context, inc Ingester)

JoinIngesters joins the ingester result statistics in a concurrency-safe manner.

func JoinResults 

func JoinResults(ctx context.Context, res Result)

JoinResults merges a Result with the embedded Result in a context in a concurrency-safe manner.
