Julius Volz	81f0b85013	Return [] instead of null for empty result vectors.	12 years ago
Julius Volz	d2da21121c	Implement getValueRangeAtIntervalOp for faster range queries. ... This also short-circuits optimize() for now, since it is complex to implement for the new operator, and ops generated by the query layer already fulfill the needed invariants. We should still investigate later whether to completely delete operator optimization code or extend it to support getValueRangeAtIntervalOp operators.	12 years ago
Matt T. Proud	30b1cf80b5	WIP - Snapshot of Moving to Client Model.	12 years ago
Julius Volz	0226d1ac7a	Implement alerts dashboard and expression console links.	12 years ago
Julius Volz	fc97e688c6	Improve printing of rules and expressions.	12 years ago
Julius Volz	74cb676537	Implement Stringer interface for rules and all their children.	12 years ago
Julius Volz	51689d965d	Add debug timers to instant and range queries. ... This adds timers around several query-relevant code blocks. For now, the query timer stats are only logged for queries initiated through the UI. In other cases (rule evaluations), the stats are simply thrown away. My hope is that this helps us understand where queries spend time, especially in cases where they sometimes hang for unusual amounts of time.	12 years ago
Julius Volz	138334fb31	Fix handling of negative deltas for non-counter values.	12 years ago
Julius Volz	66d4620061	Don't assume delta has at least one sample per vector element.	12 years ago
Julius Volz	21c3be0814	Skip any empty range/boundary elements, not only nil ones.	12 years ago
Matt T. Proud	c10780c966	Introduce telemetry for rule evaluator durations. ... This commit adds telemetry for the Prometheus expression rule evaluator, which will enable meta-Prometheus monitoring of customers to ensure that no instance is falling behind in answering routine queries. A few other sundry simplifications are introduced, too.	12 years ago
Julius Volz	750f862d9a	Use GetBoundaryValues() for non-counter deltas.	12 years ago
Julius Volz	5b105c77fc	Repointerize fingerprints.	12 years ago
Matt T. Proud	8f4c7ece92	Destroy naked returns in half of corpus. ... The use of naked return values is frowned upon. This is the first of two bulk updates to remove them.	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
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	dcf2e82752	Cleanup and idiomaticize rule/expression dot graph output.	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
