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

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	965a71dc4d	Merge pull request #1155 from prometheus/irate ... promql: Add irate() function	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
Julius Volz	0088aa4d45	Merge pull request #1132 from prometheus/fix-quoting-and-escaping ... Support escape sequences in strings and add raw strings	9 years ago
Julius Volz	46c5260761	Support escape sequences in strings and add raw strings. ... This adapts some functionality from the Go standard library for string literal lexing and unquoting/unescaping. The following string types are now supported: Double- or single-quoted strings: These support all escape sequences that Go supports in double-quoted string literals. The difference is that Prometheus also has single-quoted strings (instead of single-quoted runes in Go). Raw newlines are not allowed. Backtick-quoted raw strings: Strings quoted in backticks are treated as raw strings just like in Go and may contain raw newlines and other special characters directly.

Brian Brazil	ce7f31e03c	promql: Bump sleep in query timeout test ... This test is flaky, I'm presuming the time.AfterFunc call is being delayed so the evaluation isn't getting cancelled.	9 years ago
Julius Volz	347630431c	Merge pull request #1077 from prometheus/cleanups ... Fix some dead code, missing error checks, shadowings.	9 years ago
Julius Volz	af513468eb	Fix some dead code, missing error checks, shadowings. ... I applied https://medium.com/@jgautheron/quality-pipeline-for-go-projects-497e34d6567 and was greeted with a deluge of warnings, most of which were not applicable or really fixable realistically. These are some of the first ones I decided to fix.	9 years ago

Brian Brazil	9b382647b5	Remove optional vector() 2nd argument	9 years ago
Fabian Reinartz	a1617d90f4	Merge pull request #1073 from prometheus/whats-our-vector-victor ... promql: Add vector function.	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
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	744d5d5a7a	Merge pull request #1029 from prometheus/vet-fixes ... Fix "go vet" errors.	9 years ago
Julius Volz	995d3b831d	Fix most golint warnings. ... This is with `golint -min_confidence=0.5`. I left several lint warnings untouched because they were either incorrect or I felt it was better not to change them at the moment.	9 years ago
Julius Volz	963ad82dcb	Fix "go vet" errors. ... I ignored all errors of the type "composite literal uses unkeyed fields". Most of them are wrong because of https://github.com/golang/go/issues/9171.	9 years ago
Julius Volz	077a753e6b	Merge pull request #1006 from prometheus/true-values ... promql: Remove interpolation of vector values.	9 years ago
Fabian Reinartz	d6b8da8d43	Switch promql types to common/model	9 years ago
Brian Brazil	fb585e4591	promql: Remove interpolation of vector values. ... The current behaviour produces values that are not from rules or scrapes. So if for example I have a boolean 0/1 it can be returned as 0.2344589. This prevents a number of advanced use cases, introduces race conditions and can produce misleading graphs.	9 years ago

Brian Brazil	e6a67476c2	rules: Allow recorded rules expressions to be scalars. ... This is useful if you want to build up a constant metric, such as a set of alert thresholds that vary by label value.	9 years ago

Fabian Reinartz	690b5f1575	Remove multi-statement queries ... This commit removes the possibility to have multi-statement queries which had no full support anyway. This makes the caller responsible for multi-statement semantics. Multiple tests are no longer timing-dependent.	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
