beorn7	c740789ce3	Improve predict_linear Fixes https://github.com/prometheus/prometheus/issues/1401 This remove the last (and in fact bogus) use of BoundaryValues. Thus, a whole lot of unused (and arguably sub-optimal / ugly) code can be removed here, too.	9 years ago
Brian Brazil	c77c3a8c56	promql: Limit extrapolation of delta/rate/increase The new implementation detects the start and end of a series by looking at the average sample interval within the range. If the first (last) sample in the range is more than 1.1*interval distant from the beginning (end) of the range, it is considered the first (last) sample of the series as a whole, and extrapolation is limited to half the interval (rather than all the way to the beginning (end) of the range). In addition, if the extrapolated starting point of a counter (where it is zero) is within the range, it is used as the starting point of the series. Fixes #581	9 years ago
Brian Brazil	bac1f28cad	Similar to topk/bottomk, have sort/sort_desc put NaN at end. This makes topk and bottomk consistent with the sorting functions, as per #1271.	9 years ago
Brian Brazil	88ca82304c	Make topk/bottomk prefer returning real numbers over NaN.	9 years ago
Brian Brazil	edf3e123f5	Move topk/bottomk tests from legacy.	9 years ago
James Sanford	5b53262b7a	promql: Add clamp_max/clamp_min functions.	9 years ago
Brian Brazil	f08abdb48b	promql: Add irate() function irate is a rate function that only looks at the most recent two data points, and calucaltes a per-second value from that. This produces much more granular graphs for fast moving data, and works sanely across many scrape intervals. It doesn't do so well for slowly moving data.	9 years ago
Brian Brazil	9b382647b5	Remove optional vector() 2nd argument	9 years ago
Brian Brazil	69f5fa0c1e	promql: Add vector function. Currently the only way to convert a scalar to a vector is to use absent(), which isn't very clean. This adds a vector() function that's the inverse of scalar() and lets your optionally set labels. Example usage would be vector(time() % 86400) < 3600 to filter to only the first hour of the day.	9 years ago
Julius Volz	61c42c8da0	Change relabel_replace() to do full-string matches. THIS IS A BREAKING CHANGE. Fixes part of https://github.com/prometheus/prometheus/issues/996	9 years ago
Julius Volz	27ed874358	Implement label_replace() Implements part of https://github.com/prometheus/prometheus/issues/959.	9 years ago
Brian Brazil	d6a80c2b76	promql: Add support for predict_linear(my_timeseries[1h], 7200) This will give a prediction for the value of my_timeseries in 2 hours, based on the last hour of data.	9 years ago
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.	10 years ago
Julius Volz	d44a89c6e8	Implement changes() function. changes() takes a range vector and returns the number of times a value has changed in the given time window for each time series as an instant vector.	10 years ago
Julius Volz	6f33ed9e59	Add resets() function to count counter resets. resets() returns for every range vector element how many counter resets there have been in the specified range.	10 years ago
