var XFunctions = map[string]*parser.Function{ "xdelta": { Name: "xdelta", ArgTypes: []parser.ValueType{parser.ValueTypeMatrix}, ReturnType: parser.ValueTypeVector, }, "xincrease": { Name: "xincrease", ArgTypes: []parser.ValueType{parser.ValueTypeMatrix}, ReturnType: parser.ValueTypeVector, }, "xrate": { Name: "xrate", ArgTypes: []parser.ValueType{parser.ValueTypeMatrix}, ReturnType: parser.ValueTypeVector, }, }
Functions ¶
func IsExtFunction ¶
IsExtFunction is a convenience function to determine whether extended range calculations are required.
func RegisterXFunctions ¶ added in v0.8.0
func RegisterXFunctions()
RegisterXFunctions makes the custom x-functions (xrate, xincrease, xdelta) available to the PromQL parser by adding them to the global parser.Functions table. Since prometheus v0.312 the parser no longer accepts a custom function map at construction time, so this global registration is the only way to make the engine parse these functions.
func UnknownFunctionError ¶
func UnsupportedOperationErr ¶
