Julius Volz	ff53d10849	Fix double slash in GeneratorURL sent to alertmanager. Fixes https://github.com/prometheus/prometheus/issues/722	10 years ago
Julius Volz	267fd34156	Switch Prometheus to use github.com/prometheus/log. This change is conceptually very simple, although the diff is large. It switches logging from "github.com/golang/glog" to "github.com/prometheus/log", while not actually changing any log messages. V(1)-style logging has been changed to be log.Debug*().	10 years ago
Mitsuhiro Tanda	3e914a8cb1	fix graph links with path prefix	10 years ago
Fabian Reinartz	bb540fd9fd	Implement config reloading on SIGHUP. With this commit, sending SIGHUP to the Prometheus process will reload and apply the configuration file. The different components attempt to handle failing changes gracefully.	10 years ago
Fabian Reinartz	5fbde88919	Switch config to YAML format.	10 years ago
Fabian Reinartz	b5a8f7b8fa	Cleanup, test, and document config.	10 years ago
Fabian Reinartz	fe935179cd	Stop routing rule statements through the engine.	10 years ago
Fabian Reinartz	479891c9be	Rename RuleManager to Manager, remove interface. This commits renames the RuleManager to Manager as the package name is 'rules' now. The unused layer of abstraction of the RuleManager interface is removed.	10 years ago
Fabian Reinartz	25cdff3527	Remove `name` arg from `Parse*` functions, enhance parsing errors.	10 years ago
Fabian Reinartz	3ca11bcaf5	Switch Prometheus to promql package. This commit removes all functionality from rules/ that is now handled in promql/. All parts of Prometheus are changed to use the promql/ package.	10 years ago

Brian Brazil	6c1689f0c6	Sort NaN as the lowest value. Currently it ends up in a random position.	10 years ago
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	624f27f4b6	Add ln, log2, log10 and exp functions to the query language.	10 years ago
Julius Volz	b2651027fc	Fix special value handling in division and modulo. This fixes https://github.com/prometheus/prometheus/issues/597	10 years ago
beorn7	be11cb2b07	Remove the sample ingestion channel. The one central sample ingestion channel has caused a variety of trouble. This commit removes it. Targets and rule evaluation call an Append method directly now. To incorporate multiple storage backends (like OpenTSDB), storage.Tee forks the Append into two different appenders. Note that the tsdb queue manager had its own queue anyway. It was a queue after a queue... Much queue, so overhead... Targets have their own little buffer (implemented as a channel) to avoid stalling during an http scrape. But a new scrape will only be started once the old one is fully ingested. The contraption of three pipelined ingesters was removed. A Target is an ingester itself now. Despite more logic in Target, things should be less confusing now. Also, remove lint and vet warnings in ast.go.	10 years ago
beorn7	13fcf1ddbc	Implement double-delta encoded chunks.	10 years ago
beorn7	9e85ab0eef	Apply the new signature/fingerprinting functions from client_golang. This requires the new version of client_golang (vendoring will follow in the next commit), which changes the fingerprinting for clientmodel.Metric.	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	0ac931aed1	Also support parsing float formats like "2.".	10 years ago
Julius Volz	c2ab54e9a6	Support scientific notation and special float values. This adds support for scientific notation in the expression language, as well as for all possible literal forms of +Inf/-Inf/NaN. TODO: Keep enough state in the parser/lexer to distinguish contexts in which "Inf", "NaN", etc. should be parsed as a number vs. parsed as a label name. Currently, foo{nan="bar"} would be a syntax error. However, that is an existing bug for all our reserved words. E.g. foo{sum="bar"} is a syntax error as well. This should be fixed separately.	10 years ago
beorn7	1a61bcae07	Fix plural of 'histogram'. Actually, 'histogram' is Ancient Greek and 3rd declension... ;-)	10 years ago
beorn7	17443d288b	Avoid copying of the COWMetric if we already have the metric available.	10 years ago
beorn7	9e7c3e3bcd	Add the histogram_quantile function. Since we are now getting really deep into floating point calculation, the tests had to take into account the precision loss. Since the rule tests are based on direct line matching in the output, implementing the "almost equal" semantics was pretty cumbersome, but here we are.	10 years ago
Julius Volz	42601acfde	Replace labelsToKey() with metric Fingerprint (fixes grouping bug).	10 years ago
Julius Volz	7fefccd929	Write() directly into hash and use model.SeparatorByte.	10 years ago
Julius Volz	645cf57bed	Fix aggregation grouping key calculation.	10 years ago
Julius Volz	15b2b5aa66	Add tests for invalid uses of "offset".	10 years ago
Julius Volz	67e20acc6c	Lower-case some package-internal names.	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. This fixes https://github.com/prometheus/prometheus/issues/529 This fixed https://github.com/prometheus/promdash/issues/201	10 years ago
Brian Brazil	60271d58bf	Change the 2nd argument of round to toNearest. This is more useful if you want get a multiple of 2 or 5, while still working for .001.	10 years ago
Julius Volz	82613527f3	Remove unnecessary float64() conversion in round().	10 years ago
Marko Mikulicic	8fdacbdf17	Add floor, ceil and round functions. Closes #402	10 years ago
Fabian Reinartz	fa1e90003b	Query timeout added. This is related to #454. Queries now timeout after a duration set by the -query.timeout flag. The TotalEvalTimer is now started/stopped inside any of the ast.Eval* functions.	10 years ago
Bjoern Rabenstein	26e22e6ad6	Fix rule manager shutdown.	10 years ago
