Fabian Reinartz	af3a6661ed	Implement new alerting rule syntax	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	4e4b468fba	Fix lexer bug treating non-Latin Unicode digits as digits. Fixes https://github.com/prometheus/prometheus/issues/939	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
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

Fabian Reinartz	a236c01457	Add time series description parsing. This commit adds parsing of time series description to the exisiting query language parser. Time series descriptions are defined by a metric followed by a sequence of values.	10 years ago

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
