Brian Brazil	f34de493d5	Add increase() function, to replace delta(..., 1). ... This calculates how much a counter increases over a given period of time, which is the area under the curve of it's rate. increase(x[5m]) is equivilent to rate(x[5m]) * 300.	11 years ago
Fabian Reinartz	5602328c7c	Refactor query evaluation. ... This copies the evaluation logic from the current rules/ package. The new engine handles the execution process from query string to final result. It provides query timeout and cancellation and general flexibility for future changes. functions.go: Add evaluation implementation. Slight changes to in/out data but not to the processing logic. quantile.go: No changes. analyzer.go: No changes. engine.go: Actually new part. Mainly consists of evaluation methods which were not changed. setup_test.go: Copy of rules/helpers_test.go to setup test storage. promql_test.go: Copy of rules/rules_test.go.	11 years ago
Brian Brazil	941f585164	Avoid +InfYs and similar, just display +Inf.	11 years ago
beorn7	9e85ab0eef	Apply the new signature/fingerprinting functions from client_golang. ... This requires the new version of client_golang (vendoring will follow in the next commit), which changes the fingerprinting for clientmodel.Metric.	11 years ago
beorn7	17443d288b	Avoid copying of the COWMetric if we already have the metric available.	11 years ago
beorn7	9e7c3e3bcd	Add the histogram_quantile function. ... Since we are now getting really deep into floating point calculation, the tests had to take into account the precision loss. Since the rule tests are based on direct line matching in the output, implementing the "almost equal" semantics was pretty cumbersome, but here we are.	11 years ago
