Functions

func AlphabeticallyByPart

func AlphabeticallyByPart(metrics []*types.MetricData, part int) sort.Interface

AlphabeticallyByPart returns a byPartAlphabetical that will sort 'metrics' alphabetically by 'part'.

func ByPart

func ByPart(metrics []*types.MetricData, part int) byPartBase

ByPart returns a byPartBase suitable for sorting 'metrics' by 'part'.

func EvalExpr

func EvalExpr(ctx context.Context, e parser.Expr, from, until int32, values map[parser.MetricRequest][]*types.MetricData, getTargetData interfaces.GetTargetData) ([]*types.MetricData, error)

EvalExpr is the main expression evaluator

func SortMetrics

func SortMetrics(metrics []*types.MetricData, mfetch parser.MetricRequest)

SortMetrics sort metric data alphabetically.
