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	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
Fabian Reinartz	9ee91062c4	Merge pull request #1522 from prometheus/unless-operator ... Implement relative complement set operator "unless"	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

Julius Volz	9b6d69610a	Fix various typos in comments. ... Helpfully reported by https://goreportcard.com/report/github.com/prometheus/prometheus :)	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
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
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
Fabian Reinartz	4209ec6864	Change WITH keyword to LABELS	9 years ago
Fabian Reinartz	af3a6661ed	Implement new alerting rule syntax	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
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.

Fabian Reinartz	e3b6ec9784	Switch to common/log	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	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

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	749ae450c5	promql: add runbook to alert statement. ... This commit adds the RUNBOOK keyword to alert statements. The field is optional and expected to be a link.	10 years ago
Fabian Reinartz	94cd321be1	promql: error if all label matchers are empty.	10 years ago
Julius Volz	5e2d1c1464	Deprecate `keeping_extra`, rename it to `keep_common`. ... `keep_common` is more in line with the function name `drop_common_labels()` terminology-wise, and also more in line with `group_left`/`group_right` (no `...ing` verb suffix). We could also go the full way and call it `keep_common_labels`. That would have the benefit of being even more consistent with the function `drop_common_labels()` and would be more explanatory, but it also seems quite long.	10 years ago
