Bernerd Schaefer	aa96c7d141	Fix rules_test.go ... This is smelly, but for now we copy a helper method from the metric tests into rules.	12 years ago
Julius Volz	83c60ad43a	Fix GetMetricForFingerprint() metric mutability. ... Some users of GetMetricForFingerprint() end up modifying the returned metric labelset. Since the memory storage's implementation of GetMetricForFingerprint() returned a pointer to the metric (and maps are reference types anyways), the external mutation propagated back into the memory storage. The fix is to make a copy of the metric before returning it.	12 years ago
Bernerd Schaefer	428d91c86f	Rename test helper files to helpers_test.go ... This ensures that these files are properly included only in testing.	12 years ago
Matt T. Proud	244a4a9cdb	Update to go1.1. ... This commit updates the documentation, Makefiles, formatting, and code semantics to support the 1.1. runtime, which includes ... 1. ``make advice``, 2. ``make format``, and 3. ``go fix`` on various targets.	12 years ago
Matt T. Proud	161c8fbf9b	Include deletion processor for long-tail values. ... This commit extracts the model.Values truncation behavior into the actual tiered storage, which uses it and behaves in a peculiar way—notably the retention of previous elements if the chunk were to ever go empty. This is done to enable interpolation between sparse sample values in the evaluation cycle. Nothing necessarily new here—just an extraction. Now, the model.Values TruncateBefore functionality would do what a user would expect without any surprises, which is required for the DeletionProcessor, which may decide to split a large chunk in two if it determines that the chunk contains the cut-off time.	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	56324d8ce2	Make AST query storage non-global.	12 years ago
Matt T. Proud	ce45787dbf	Storage interface to TieredStorage. ... This commit drops the Storage interface and just replaces it with a publicized TieredStorage type. Storage had been anticipated to be used as a wrapper for testability but just was not used due to practicality. Merely overengineered. My bad. Anyway, we will eventually instantiate the TieredStorage dependencies in main.go and pass them in for more intelligent lifecycle management. These changes will pave the way for managing the curators without Law of Demeter violations.	12 years ago
Julius Volz	9cea5d9df8	Convert the Prometheus configuration to protocol buffers.	12 years ago
Julius Volz	d8110fcd9c	Send sample arrays instead of single samples over channels.	12 years ago

Matt T. Proud	b3e34c6658	Implement batch database sample curator. ... This commit introduces to Prometheus a batch database sample curator, which corroborates the high watermarks for sample series against the curation watermark table to see whether a curator of a given type needs to be run. The curator is an abstract executor, which runs various curation strategies across the database. It remarks the progress for each type of curation processor that runs for a given sample series. A curation procesor is responsible for effectuating the underlying batch changes that are request. In this commit, we introduce the CompactionProcessor, which takes several bits of runtime metadata and combine sparse sample entries in the database together to form larger groups. For instance, for a given series it would be possible to have the curator effectuate the following grouping: - Samples Older than Two Weeks: Grouped into Bunches of 10000 - Samples Older than One Week: Grouped into Bunches of 1000 - Samples Older than One Day: Grouped into Bunches of 100 - Samples Older than One Hour: Grouped into Bunches of 10 The benefits hereof of such a compaction are 1. a smaller search space in the database keyspace, 2. better employment of compression for repetious values, and 3. reduced seek times.	12 years ago

Julius Volz	c0601abf46	Implement initial no-op alert parsing and rule parsing tests.	12 years ago
Matt T. Proud	f9e99bd08a	Refresh SampleValue to 64-bit floating point. ... We always knew that this needed to be fixed.	12 years ago
Julius Volz	99dcbe0f94	Integrate memory and disk layers in view rendering.	12 years ago
Julius Volz	63625bd244	Make view use memory persistence, remove obsolete code. ... This makes the memory persistence the backing store for views and adjusts the MetricPersistence interface accordingly. It also removes unused Get* method implementations from the LevelDB persistence so they don't need to be adapted to the new interface. In the future, we should rethink these interfaces. All staleness and interpolation handling is now removed from the storage layer and will be handled only by the query layer in the future.	12 years ago

Matt T. Proud	efe61c18fa	Refactor target scheduling to separate facility. ... ``Target`` will be refactored down the road to support various nuanced endpoint types. Thusly incorporating the scheduling behavior within it will be problematic. To that end, the scheduling behavior has been moved into a separate assistance type to improve conciseness and testability. ``make format`` was also run.	12 years ago
Julius Volz	cb6eb30182	Fix state cleanup bug between rule/config parser runs. ... This fixes a bug that has been annoying me minorly for some time now: sometimes, after parse errors, a subsequent parser run would fail. The reason is that yylex() modifies some global variables (yytext, yydata) during its run to keep state. To make subsequent parser runs correct, these have to be reset before each run. Also, close files after reading them.	12 years ago
