Types ¶
type ErrEvalExpr ¶
type ErrEvalExpr struct {
// contains filtered or unexported fields
}
ErrEvalExpr used when carbonapi.EvalExpr returns error
func (ErrEvalExpr) Error ¶
func (err ErrEvalExpr) Error() string
Error is implementation of golang error interface for ErrEvalExpr struct
type ErrEvaluateTargetFailedWithPanic ¶
type ErrEvaluateTargetFailedWithPanic struct {
// contains filtered or unexported fields
}
ErrEvaluateTargetFailedWithPanic used to identify occurred error as a result of recover from panic
func (ErrEvaluateTargetFailedWithPanic) Error ¶
func (err ErrEvaluateTargetFailedWithPanic) Error() string
Error is implementation of golang error interface for ErrEvaluateTargetFailedWithPanic struct
type ErrParseExpr ¶
type ErrParseExpr struct {
// contains filtered or unexported fields
}
ErrParseExpr used when carbonapi.ParseExpr returns error
func (ErrParseExpr) Error ¶
func (err ErrParseExpr) Error() string
Error is implementation of golang error interface for ErrParseExpr struct
type ErrUnknownFunction ¶
type ErrUnknownFunction struct {
FuncName string
// contains filtered or unexported fields
}
ErrUnknownFunction used when carbonapi.ParseExpr returns unknown function error
func ErrorUnknownFunction ¶
func ErrorUnknownFunction(err error) ErrUnknownFunction
ErrorUnknownFunction parses internal carbonapi error errUnknownFunction, gets func name and return ErrUnknownFunction error
func (ErrUnknownFunction) Error ¶
func (err ErrUnknownFunction) Error() string
Error is implementation of golang error interface for ErrUnknownFunction struct
type EvaluationResult ¶
type EvaluationResult struct {
TimeSeries []*TimeSeries
Patterns []string
Metrics []string
}
EvaluationResult represents evaluation target result and contains TimeSeries list, Pattern list and metric lists appropriate to given target
func EvaluateTarget ¶
func EvaluateTarget(database moira.Database, target string, from int64, until int64, allowRealTimeAlerting bool) (*EvaluationResult, error)
EvaluateTarget is analogue of evaluateTarget method in graphite-web, that gets target metrics value from DB and Evaluate it using carbon-api eval package
type TimeSeries ¶
type TimeSeries struct {
types.MetricData
Wildcard bool
}
TimeSeries is abstraction over carbon-api types.MetricData type
func (*TimeSeries) GetTimestampValue ¶
func (timeSeries *TimeSeries) GetTimestampValue(valueTimestamp int64) float64
GetTimestampValue gets value of given timestamp index, if value is Nil, then return NaN
