Matt T. Proud	39a3e69779	Merge pull request #263 from prometheus/ui/negative-graph-values ... Support negative graph values.	12 years ago
Julius Volz	8586c7520c	Support negative graph values. ... Currently graph Y-Axes were hardcoded to start at 0. Choose the Y-scale automatically based on the graph data instead.	12 years ago
juliusv	1958063cc7	Merge pull request #262 from prometheus/feature/storage/fix-grouping ... Spawn grouping of fingerprints with free semaphore.	12 years ago
Matt T. Proud	74a66fd938	Spawn grouping of fingerprints with free semaphore. ... The previous implementation spawned N goroutines to group samples together and would not start work until the semaphore unblocked. While this didn't leak, it polluted the scheduling space. Thusly, the routine only starts after a semaphore has been acquired.	12 years ago

Matt T. Proud	ec5b5bae28	Fuck you, Travis.	12 years ago
Matt T. Proud	e5ac91222b	Benchmark memory arena; simplify map generation. ... The one-off keys have been replaced with ``model.LabelPair``, which is indexable. The performance impact is negligible, but it represents a cognitive simplification.	12 years ago
juliusv	360477f66c	Merge pull request #257 from prometheus/feature/better-memory-behaviors ... Pointerize memorySeriesArena.	12 years ago
Matt T. Proud	e1f20de2e9	Pointerize memorySeriesArena.	12 years ago
juliusv	e5d077e146	Merge pull request #254 from prometheus/feature/refactor/serialization ... Several Refactorings: Simplified Encoder / Reduction of Naked Return Values	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
Matt T. Proud	4e0c932a4f	Simplify Encoder's encoding signature. ... The reality is that if we ever try to encode a Protocol Buffer and it fails, it's likely that such an error is ultimately not a runtime error and should be fixed forthwith. Thusly, we should rename ``Encoder.Encode`` to ``Encoder.MustEncode`` and drop the error return value.	12 years ago
juliusv	e54edb16a5	Merge pull request #252 from prometheus/feature/larger-in-memory-arena ... Expand the in-memory arena size.	12 years ago
Matt T. Proud	b063338ae6	Expand the in-memory arena size. ... We need to exercise this code path sooner versus later. This will be a cheap way of doing so.	12 years ago
juliusv	516101f015	Merge pull request #250 from prometheus/refactor/drop-unused-storage-setting ... Drop unused writeMemoryInterval	12 years ago
juliusv	9ff00b651d	Merge pull request #251 from prometheus/fix/memory-metric-mutability ... Fix GetMetricForFingerprint() metric mutability.	12 years ago
Bernerd Schaefer	63d9988b9c	Drop unused writeMemoryInterval	12 years ago
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
Matt T. Proud	dab017e8cf	Merge pull request #249 from prometheus/fix/test-flag-pollution ... Rename test helper files to helpers_test.go	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	1a95406b81	Include forgotten databases.html.	12 years ago
Matt T. Proud	9a8fb58fa6	Merge pull request #245 from prometheus/feature/runtime/go1.1 ... ¡ DONOTMERGE — Update to go1.1. !	12 years ago
Julius Volz	71a3172abb	Fix and optimize getValuesAtIntervalOp data extraction. ... - only the data extracted in the last loop iteration of ExtractSamples() was emitted as output - if e.g. op interval < sample interval, there were situations where the same sample was added multiple times to the output	12 years ago
Matt T. Proud	8956ebe0c6	Include "Travis Helper".	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	2ea2e89c97	Merge pull request #244 from prometheus/feature/database-statistics-exposition ... Simplify compaction and expose database sizes.	12 years ago
Matt T. Proud	b224251981	Simplify compaction and expose database sizes. ... This commit simplifies the way that compactions across a database's keyspace occur due to reading the LevelDB internals. Secondarily it introduces the database size estimation mechanisms. Include database health and help interfaces. Add database statistics; remove status goroutines. This commit kills the use of Go routines to expose status throughout the web components of Prometheus. It also dumps raw LevelDB status on a separate /databases endpoint.	12 years ago
juliusv	92ad65ff13	Merge pull request #232 from prometheus/optimize/granular-storage-locking ... Synchronous memory appends and more fine-grained storage locks.	12 years ago
Matt T. Proud	dad20c15e7	Merge pull request #243 from prometheus/feature/size-exposition ... Simplify compaction and expose database sizes.	12 years ago
Matt T. Proud	1f7f89b4e3	Simplify compaction and expose database sizes. ... This commit simplifies the way that compactions across a database's keyspace occur due to reading the LevelDB internals. Secondarily it introduces the database size estimation mechanisms.	12 years ago
Matt T. Proud	5b183f6434	Merge pull request #242 from prometheus/feature/storage/long-tail-deletion ... Include long-tail data deletion mechanism.	12 years ago
Matt T. Proud	d538b0382f	Include long-tail data deletion mechanism. ... This commit introduces the long-tail deletion mechanism, which will automatically cull old sample values. It is an acceptable hold-over until we get a resampling pipeline implemented. Kill legacy OS X documentation, too.	12 years ago
Julius Volz	ce1ee444f1	Synchronous memory appends and more fine-grained storage locks. ... This does two things: 1) Make TieredStorage.AppendSamples() write directly to memory instead of buffering to a channel first. This is needed in cases where a rule might immediately need the data generated by a previous rule. 2) Replace the single storage mutex by two new ones: - memoryMutex - needs to be locked at any time that two concurrent goroutines could be accessing (via read or write) the TieredStorage memoryArena. - memoryDeleteMutex - used to prevent any deletion of samples from memoryArena as long as renderView is running and assembling data from it. The LevelDB disk storage does not need to be protected by a mutex when rendering a view since renderView works off a LevelDB snapshot. The rationale against adding memoryMutex directly to the memory storage: taking a mutex does come with a small inherent time cost, and taking it is only required in few places. In fact, no locking is required for the memory storage instance which is part of a view (and not the TieredStorage).	12 years ago
Matt T. Proud	2a047fe416	Merge pull request #236 from prometheus/feature/tools/compactor ... Expose interfaces for pruner and make pruner tool.	12 years ago
Matt T. Proud	fa6a1f97d0	Expose interfaces for pruner and make pruner tool. ... In order to run database cleanups and diagnostics, we should have a means for pruning a database---even if LevelDB does this for us.	12 years ago
juliusv	76521c3ff0	Merge pull request #234 from prometheus/feature/storage/long-tail-deletion ... Include deletion processor for long-tail values.	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
juliusv	8d062ebb27	Merge pull request #219 from prometheus/refactor/version-protocol-buffer ... Include generated Protocol Buffers artifacts.	12 years ago
juliusv	0dc15d28cb	Merge pull request #233 from prometheus/feature/count-by ... Implement a COUNT ... BY aggregation operator.	12 years ago
Matt T. Proud	38d839d810	Include generated Protocol Buffers artifacts. ... This commit reduces the general compile time dependencies to omit the Protocol Buffer compiler and the Go Protocol Buffer generator tool. The build steps to furnish them still remain, but they can optionally be called if data.proto or config.proto are under work.	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
Bernerd Schaefer	1c9b5b6b8d	Merge pull request #221 from prometheus/fix/race-conditions ... Fix/document race conditions	12 years ago
