Brian Brazil	c3a2b63fe9	Add stddev and stdvar aggregation functions. This adds the population standard deviation and variance as aggregation functions, useful for spotting how many standard deviations some samples are from the mean.	10 years ago
Fabian Reinartz	182de6b99f	Fix unary +/- expressions. Unary expressions cause parsing errors if they are done in the lexer by tokenizing them into the number. This fix moves unary expressions to the parser.	10 years ago
Fabian Reinartz	6f754073d5	Add OR operation and vector matching options. This commits implements the OR operation between two vectors. Vector matching using the ON clause is added to limit the set of labels that define a match between two elements. Group modifiers (GROUP_LEFT/GROUP_RIGHT) to request many-to-one matching are added.	10 years ago
Julius Volz	72d7b325a1	Implement offset operator. This allows changing the time offset for individual instant and range vectors in a query. For example, this returns the value of `foo` 5 minutes in the past relative to the current query evaluation time: foo offset 5m Note that the `offset` modifier always needs to follow the selector immediately. I.e. the following would be correct: sum(foo offset 5m) // GOOD. While the following would be incorrect: sum(foo) offset 5m // INVALID. The same works for range vectors. This returns the 5-minutes-rate that `foo` had a week ago: rate(foo[5m] offset 1w) This change touches the following components: * Lexer/parser: additions to correctly parse the new `offset`/`OFFSET` keyword. * AST: vector and matrix nodes now have an additional `offset` field. This is used during their evaluation to adjust query and result times appropriately. * Query analyzer: now works on separate sets of ranges and instants per offset. Isolating different offsets from each other completely in this way keeps the preloading code relatively simple. No storage engine changes were needed by this change. The rules tests have been changed to not probe the internal implementation details of the query analyzer anymore (how many instants and ranges have been preloaded). This would also become too cumbersome to test with the new model, and measuring the result of the query should be sufficient.

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
Brian Brazil	ffa2e73803	Fix regression from `5e8d57bec1` 0 is a false value, so shortcutting no longer works. Update other places in the code that assumed graph was the default.	10 years ago
Julius Volz	cc27fb8aab	Rename remaining all-caps constants in AST layer. Change-Id: Ibe97e30981969056ffcdb89e63c1468ea1ffa140	10 years ago
Bjoern Rabenstein	b1e4956142	Apply a giant code cleanup. Essentially: - Remove unused code. - Make it 'go vet' clean. The only remaining warnings are in generated code. - Make it 'golint' clean. The only remaining warnings are in gerenated code. - Smoothed out same minor things. Change-Id: I3fe5c1fbead27b0e7a9c247fee2f5a45bc2d42c6	10 years ago
Brian Brazil	8be993b8f8	Let consoles get graph links from experssions. Rename ConsoleLinkFromExpression, as we now have consoles. Change-Id: I7ed2c9c83863adb390b51121dd9736845f7bcdfc	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. Change-Id: I510a83f761198e80946146770ebb64e4abc3bb96	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	1eb1ceac8c	Add alert-expression console links to notifications. The ConsoleLinkForExpression() function now escapes console URLs in such a way that works both in emails and in HTML. Change-Id: I917bae0b526cbbac28ccd2a4ec3c5ac03ee4c647	11 years ago
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	0226d1ac7a	Implement alerts dashboard and expression console links.	12 years ago
Julius Volz	74cb676537	Implement Stringer interface for rules and all their children.	12 years ago
Julius Volz	0877680761	Implement a COUNT ... BY aggregation operator. This also removes the now obsolete scalar count() function and corrects the expressions test naming (broken in `2202cd71c9 (L6R59)`) so that the expression tests will actually run.	12 years ago
Julius Volz	c0601abf46	Implement initial no-op alert parsing and rule parsing tests.	12 years ago
