Suggested by @grobie: https://github.com/prometheus/prometheus/pull/1984#issuecomment-246508286 `1136239445` is the reference time used by Go: https://golang.org/src/time/format.go	8 years ago
Matt Bostock	9628eb5998	PromQL: Add minute() function ... Returns the minutes from the current time in UTC. Related to the `hour()` function. Fixes #1983.	8 years ago

Brian Brazil	fd7822829c	Add date related functions. ... Add day_of_month, day_of_week, hour_of_day, month_of_year and year. This only work for UTC, and ignore leap seconds the same as Go.	8 years ago

Brian Brazil	40f8da699e	Merge pull request #1815 from prometheus/stddev ... Add stddev_over_time and stdvar_over_time.	8 years ago
Brian Brazil	1edd6875f5	Add stddev_over_time and stdvar_over_time.	8 years ago
Brian Brazil	16690736ab	Add count_values() aggregator. ... This is useful for counting how many instances of a job are running a particular version/build. Fixes #622	9 years ago
Brian Brazil	fa9cc15573	Add topk/bottomk tests for multiple buckets.	9 years ago
Brian Brazil	3b0c182eee	Move topk/bottomk unittests over to aggregators.	9 years ago
Brian Brazil	3b89616d82	Allow on, ignoring, by and without wit empty laberls. ... This offers new semantics in allowing on() for matching two single-element vectors with no known common labels. Previosuly this was often done using on(dummy). This also allows making it explict that you meant to do an aggregation without labels via by(). Fixes #1597.	9 years ago

Brian Brazil	ef55fd6176	Add unittest for using a metric for thresholds with group_left.	9 years ago
Brian Brazil	d991f0cf47	For many-to-one matches, always copy label from one side. ... This is a breaking change for everyone using the machine roles labeling approach.	9 years ago
Brian Brazil	768d09fd2a	Change on+group_* to take copy from the one side. ... If the label doesn't exist on the one side, it's not copied. All labels on the many inside are included, this is a breaking change but likely low impact.	9 years ago
Brian Brazil	d1edfb25b3	Add support for OneToMany with IGNORING. ... The labels listed in the group_ modifier will be copied from the one side to the many side. It will be valid to specify no labels. This is intended to replace the existing ON/GROUP_* support.,	9 years ago
Brian Brazil	1d08c4fef0	Add 'ignoring' as modifier for binops. ... Where 'on' uses the given labels to match, 'ignoring' uses all other labels to match. group_left/right is not supported yet.	9 years ago
Brian Brazil	f5084ab1c5	Add tests for group_left/group_right	9 years ago
Tobias Schmidt	8cc86f25c0	Implement relative complement set operator "unless" ... The `unless` set operator can be used to return all vector elements from the LHS which do not match the elements on the RHS. A use case is to return all metrics for nodes which do not have a specific role: node_load1 unless on(instance) chef_role{role="app"}	9 years ago

beorn7	8766f99085	Merge branch 'beorn7/storage2' into beorn7/storage3	9 years ago
beorn7	79a2ae2d2e	Add missing test file	9 years ago
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	9d0112d7cf	Add without aggregator modifier. ... This has the advantage that the user doesn't need to list all labels they want to keep (as with "by") but without having to worry about inconsistent labels as when there's only one time series (as with "keeping_common"). Almost all aggregation should use this rather than the existing two options as it's much less error prone and easier to maintain due to not having to always add in "job" plus whatever other common job-level labels you have like "region".	9 years ago
Brian Brazil	b7ef0b45e8	Break aggregation tests out. Add missing tests.	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	89760dd77d	Handle NaN for min/max. ... Similar to topk and sort, prefer not returning NaN where possible.	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
Fabian Reinartz	33aab4169c	Anchor regexes in vector matching ... This commit makes the regex behavior of vector matching consistent with configuration and label_replace() by anchoring it. Fixes #1200	9 years ago
Fabian Reinartz	51e8badc7f	Merge pull request #1159 from prometheus/scalar-bool ... promql: Remove scalar/scalar comparisons.	9 years ago
Brian Brazil	c36961130b	promql: Remove scalar/scalar comparisons. ... This change is breaking, use the 'bool' modifier for such comprisons. After this change all comparisons without 'bool' will filter, and all comparisons with 'bool' will return 0/1. This makes the language more consistent and orthogonal, and ultimately easier to learn and use. If we ever figure out sane semantics for filtering scalar/scalar comparisons we can add them in, which will most likely come out of how the new vector() function is used.	9 years ago
Brian Brazil	5740a8fade	promql: Remove deprecated 2nd argument to delta() ... This change is breaking, use increase() instead. I'm not cleaning up the function in this PR, as my solution to #581 will rewrite and simplify increase/rate/delta.	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
Brian Brazil	9ec11b1847	Merge pull request #1049 from prometheus/bool-nofilter ... promql: Add 'bool' modifier to comparison functions	9 years ago
Brian Brazil	29e8dc2c49	promql: Add 'bool' modifier to comparison functions ... When doing comparison operations on vectors, filtering sometimes gets in the way and you have to go to a fair bit of effort to workaround it in order to always return a result. The 'bool' modifier instead of filtering returns 0/1 depending on the result of the compairson. This is also a prerequisite to removing plain scalar/scalar comparisons, as it maintains the current behaviour under a new syntax.	9 years ago
