Julius Volz	f2b48b8c4a	Make getValuesAtIntervalOp consume all chunk data in one pass. ... This is mainly a small performance improvement, since we skip past the last extracted time immediately if it was also the last sample in the chunk, instead of trying to extract non-existent values before the chunk end again and again and only gradually approaching the end of the chunk.	12 years ago
Julius Volz	83d60bed89	extractValuesAroundTime() code simplification.	12 years ago
Julius Volz	008314b5a8	Ensure that all extracted samples are added to view. ... The current behavior only adds those samples to the view that are extracted by the last pass of the last processed op and throws other ones away. This is a bug. We need to append all samples that are extracted by each op pass. This also makes view.appendSamples() take an array of samples.	12 years ago
Matt T. Proud	556be84c73	Merge pull request #265 from prometheus/feature/memory-arena-simplification ... Move In-Memory Arena Away from Skiplist	12 years ago
Matt T. Proud	93da3f684a	Instruct ``make binary`` to build binary file.	12 years ago
Matt T. Proud	b586801830	Code Review: Fix to-disk queue infinite growth. ... We discovered a bug while manually testing this branch on a live instance, whereby the to-disk queue was never actually dumped to disk.	12 years ago

Matt T. Proud	d8259cd10d	Merge pull request #266 from prometheus/tool/dumper ... Simple LevelDB sample dumper tool.	12 years ago
Julius Volz	6d68626125	Simple LevelDB sample dumper tool. ... This very simple tool dumps all samples in a LevelDB metrics storage together with their chunk information. This is very crude for now - I just whipped it up because I needed to debug something. We should add printf-style formatting support for it in the future to indicate what information to output for each sample in the database. We could also support inspecting the index databases.	12 years ago
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	053f4296d0	Merge pull request #260 from prometheus/feature/show-scrape-errors ... Remember and display last scrape errors in web UI.	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

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
