Bjoern Rabenstein	5859b74f1b	Clean up license issues. - Move CONTRIBUTORS.md to the more common AUTHORS. - Added the required NOTICE file. - Changed "Prometheus Team" to "The Prometheus Authors". - Reverted the erroneous changes to the Apache License.	10 years ago
Julius Volz	f1aac54104	Allow alternative "by"-clause position in grammar. In addition to the existing by-clause syntax: sum(<expression>) by (<labels>) [keeping_extra] ...this allows the following new syntax: sum by (<labels>) [keeping_extra] (<expression>) Both orderings may be used in a single expression. It is up to the users to establish guidelines around their usage. Change-Id: Iba10c9cc5fb6ac62edfcf246d281473e82467992	10 years ago
Julius Volz	080b952647	Allow omitting the metric name in queries. This allows the following expression syntaxes for selecting timeseries: foo (already valid before) foo{} (already valid before) {job="prometheus"} (new, select all timeseries for job "prometheus") Omitting both the metric name and any label matchers ("" or "{}") will still yield a syntax error. To get all timeseries, you could do: {__name__=~"."} or, without relying on knowledge about __metric__: {job=~"."} Change-Id: Ifee000b9ac0184ef6ced18411069c7f2699a2dda	10 years ago
Julius Volz	c7c0b33d0b	Add regex-matching support for labels. There are four label-matching ops for selecting timeseries now: - Equal: = - NotEqual: != - RegexMatch: =~ - RegexNoMatch: !~ Instead of looking up labels by a simple clientmodel.LabelSet (basically an equals op for every key/value pair in the set), timeseries fingerprint selection is now done via a list of metric.LabelMatchers.

Bjoern Rabenstein	0a65b691cc	Disallow ":" in identifiers, but still allow it in metric names. Change-Id: Iace925ab1b71a360bd63357e87f68e727f7afbcb	11 years ago
Julius Volz	3f226c9724	Rename {Scalar,Vector}Literal to {Scalar,Vector}Selector. Change-Id: Ie92301f47f5f49f30b3a62c365e377108982b080	11 years ago
Julius Volz	6dc36d0c3e	Don't keep extra labels in aggregations by default. MIN/MAX/SUM/AVG/COUNT aggregations will now by default drop all labels that are not specifically part of a BY-clause, even if a label value is the same within all timeseries of an aggregation group. The old behavior of keeping extra labels may still be switched on by adding KEEPING_EXTRA to the end of an aggregation statement: sum(http_requests) by (job, method) keeping_extra I'm open to better syntax/naming suggestions.

Julius Volz	35ee2cd3cb	Add alertmanager notification support to Prometheus. Alert definitions now also have mandatory SUMMARY and DESCRIPTION fields that get sent along a firing alert to the alert manager.	11 years ago
Julius Volz	64b0ade171	Swap rules lexer for much faster one. This swaps github.com/kivikakk/golex for github.com/cznic/golex. The old lexer would have taken 3.5 years to load a set of 5000 test rules (quadratic time complexity for input length), whereas this one takes only 32ms. Furthermore, since the new lexer is embedded differently, this gets rid of the global parser variables and makes the rule loader fully reentrant without a lock.	12 years ago
