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
beorn7	a7408bfb47	Unify duration parsing ... It's actually happening in several places (and for flags, we use the standard Go time.Duration...). This at least reduces all our home-grown parsing to one place (in model).	9 years ago
Fabian Reinartz	a6935024e1	Remove old WITH clause in alert printing	9 years ago
Tobias Schmidt	1a91cd6e09	Rename matrix to range selector in external error messages ... The documentation speaks about range vectors and range vector selectors. This change does not fix all issues, we might still expose the term "Matrix" in error messages using %T.	9 years ago
Tobias Schmidt	411ca4dba1	Consolidate offset modifier parsing ... Remove duplicated offset modifier parsing and ensure offset can only appear at the end of a selector statement.	9 years ago
Fabian Reinartz	6b4a6962d2	Support old alerting rule syntax	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

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.

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

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	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	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

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
