Julius Volz	3bfec97d46	Make the storage interface higher-level. See discussion in https://groups.google.com/forum/#!topic/prometheus-developers/bkuGbVlvQ9g The main idea is that the user of a storage shouldn't have to deal with fingerprints anymore, and should not need to do an individual preload call for each metric. The storage interface needs to be made more high-level to not expose these details. This also makes it easier to reuse the same storage interface for remote storages later, as fewer roundtrips are required and the fingerprint concept doesn't work well across the network. NOTE: this deliberately gets rid of a small optimization in the old query Analyzer, where we dedupe instants and ranges for the same series. This should have a minor impact, as most queries do not have multiple selectors loading the same series (and at the same offset).	8 years ago

Brian Brazil	246a817300	Flip vector matching to be ignoring by default. This is a noop semantically.	9 years ago
Ali Reza	e7eba75690	remove keeping_extra because it's replaced with keep_common change all keepExtra label into keepCommon, and move action into removed list change incorrect token list	9 years ago

Brian Brazil	7201c010c4	Rename On to MatchingLabels	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
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

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	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

Fabian Reinartz	c1d37bc55b	Merge pull request #843 from prometheus/fabxc/runbook promql: add runbook to alert statement.	10 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	7f85b9b215	promql: add MarshalJSON method for ExprType.	10 years ago
Fabian Reinartz	5b91ea9b36	storage: improve label matching and allow unset matching. Matching of empty labels now also matches metrics where the label was not explicitly set to the empty string.	10 years ago
Fabian Reinartz	e7659f908c	promql: remove DotGraph methods from nodes.	10 years ago
Fabian Reinartz	5602328c7c	Refactor query evaluation. This copies the evaluation logic from the current rules/ package. The new engine handles the execution process from query string to final result. It provides query timeout and cancellation and general flexibility for future changes. functions.go: Add evaluation implementation. Slight changes to in/out data but not to the processing logic. quantile.go: No changes. analyzer.go: No changes. engine.go: Actually new part. Mainly consists of evaluation methods which were not changed. setup_test.go: Copy of rules/helpers_test.go to setup test storage. promql_test.go: Copy of rules/rules_test.go.	10 years ago
Fabian Reinartz	32b7595c47	Create promql package with lexer/parser. This commit creates a (so far unused) package. It contains the a custom lexer/parser for the query language. ast.go: New AST that interacts well with the parser. lex.go: Custom lexer (new). lex_test.go: Lexer tests (new). parse.go: Custom parser (new). parse_test.go: Parser tests (new). functions.go: Changed function type, dummies for parser testing (barely changed/dummies). printer.go: Adapted from rules/ and adjusted to new AST (mostly unchanged, few additions).	10 years ago
