Matt T. Proud	2d5de99fbf	Regard in-memory series as new. This commit ensures that series that exist only in-memory and not on-disk are not regarded as too old for operation exclusion.	12 years ago
Matt T. Proud	81c406630a	Merge pull request #312 from prometheus/fix/sample-append-logging Log correct sample count when appending to disk.	12 years ago
Matt T. Proud	a1a23fbaf8	Ensure new metrics are watermarked early. With the checking of fingerprint freshness to cull stale metrics from queries, we should write watermarks early to aid in more accurate responses.	12 years ago

Julius Volz	71199e2c93	Cache disk fingerprint->metric lookups in memory.	12 years ago
Matt T. Proud	a73f061d3c	Persist solely Protocol Buffers. An design question was open for me in the beginning was whether to serialize other types to disk, but Protocol Buffers quickly won out, which allows us to drop support for other types. This is a good start to cleaning up a lot of cruft in the storage stack and can let us eventually decouple the various moving parts into separate subsystems for easier reasoning. This commit is not strictly required, but it is a start to making the rest a lot more enjoyable to interact with.	12 years ago

Matt T. Proud	2c3df44af6	Ensure database access waits until it is started. This commit introduces a channel message to ensure serving state has been reached with the storage stack before anything attempts to use it.	12 years ago
Matt T. Proud	cbe2f3a7b1	Include LRU cache for fingerprint watermarks.	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
Matt T. Proud	8339a189cb	Code Review: Fix seriesPresent scope. The seriesPresent scope should be constrained to the scope of a scanJob, since this is keyed to given series.	12 years ago
Matt T. Proud	fe41ce0b19	Conditionalize disk initializations. This commit conditionalizes the creation of the diskFrontier and seriesFrontier along with the iterator such that they are provisioned once something is actually required from disk.	12 years ago
Julius Volz	a8468a2e5e	Fix reversed disk flush cutoff behavior.	12 years ago
Julius Volz	eb1f956909	Revert "Revert "Ensure that all extracted samples are added to view."" This reverts commit `4b30fb86b4`.	12 years ago
Matt T. Proud	4b30fb86b4	Revert "Ensure that all extracted samples are added to view." This reverts commit `008314b5a8`. By running an automated git bisection described in https://gist.github.com/matttproud-soundcloud/22a371a8d2cba382ea64 this commit was found.	12 years ago
Julius Volz	750f862d9a	Use GetBoundaryValues() for non-counter deltas.	12 years ago
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	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	c07abf8521	Initial move away from skiplist.	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

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	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
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
juliusv	98e512d755	Merge pull request #246 from prometheus/fix/interval-value-extraction Fix and optimize getValuesAtIntervalOp data extraction.	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	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	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	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	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	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
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
Matt Proud	7f0d816574	Schedule the background compactors to run. This commit introduces three background compactors, which compact sparse samples together. 1. Older than five minutes is grouped together into chunks of 50 every 30 minutes. 2. Older than 60 minutes is grouped together into chunks of 250 every 50 minutes. 3. Older than one day is grouped together into chunks of 5000 every 70 minutes.	12 years ago

Matt T. Proud	f897164bcf	Expose TieredStorage.DiskStorage.	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
Bernerd Schaefer	5eb9840ed7	Fix goroutine leak in leveldb.AppendSamples The error channels in AppendSamples need to be buffered, since in the presence of errors their values may not be consumed.	12 years ago

Matt T. Proud	6fac20c8af	Harden the tests against OOMs. This commit employs explicit memory freeing for the in-memory storage arenas. Secondarily, we take advantage of smaller channel buffer sizes in the test.	12 years ago

Matt T. Proud	a48ab34dd0	Refresh Prometheus client API usage. The client API has been updated per https://github.com/prometheus/client_golang/pull/9.	12 years ago
Matt T. Proud	561974308d	Add curation remark table and refactor error mgmt. The curator requires the existence of a curator remark table, which stores the progress for a given curation policy. The tests for the curator create an ad hoc table, but core Prometheus presently lacks said table, which this commit adds. Secondarily, the error handling for the LevelDB lifecycle functions in the metric persistence have been wrapped into an UncertaintyGroup, which mirrors some of the functions of sync.WaitGroup but adds error capturing capability to the mix.	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

Matt T. Proud	05504d3642	WIP - Truncate irrelevant chunk values. This does not work with the view tests.	12 years ago
Matt T. Proud	a32602140e	Convert the TestInstant value into UTC. For the forthcoming Curator, we don't record timezone information in the samples, nor do we in the curation remarks. All times are recorded UTC. That said, for the test environment to better match production, the special instant should be in UTC.	12 years ago
Matt T. Proud	b1a8e51b07	Extract dto.SampleValueSeries into model.Values.	12 years ago
Matt T. Proud	422003da8e	Convert trailing float64s.	12 years ago
Matt T. Proud	db4ffbb262	Wrap dto.SampleKey with business logic type. The curator work can be done easier if dto.SampleKey is no longer directly accessed but rather has a higher level type around it that captures a certain modicum of business logic. This doesn't look terribly interesting today, but it will get more so.	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
Matt T. Proud	092c7bd88e	Stochastic test support plural SampleValueSeries. After SampleValue was refactored into SampleValueSeries, which involves plural values under a common super key, the stochastic test was never refreshed to reflect this reality. We had other tests that validated the functionality, but this one was insufficently forward-ported.	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	d468271e2f	Fix append queue telemetry and parameterize sizes. The original append queue telemetry never worked, because it was updated only upon the exit of the select statement, which would usually liberate the queues of contents. This has been fixed to be reported arbitrarily. The queue sizes are now parameterizable via flags.	12 years ago
Julius Volz	95b081f9bc	Stop serving tiered storage after draining it.	12 years ago
Matt T. Proud	a55602df4a	Validate diskFrontier domain for series candidate. It is the case with the benchmark tool that we thought that we generated multiple series and saved them to the disk as such, when in reality, we overwrote the fields of the outgoing metrics via Go map reference behavior. This was accidental. In the course of diagnosing this, a few errors were found: 1. ``newSeriesFrontier`` should check to see if the candidate fingerprint is within the given domain of the ``diskFrontier``. If not, as the contract in the docstring stipulates, a ``nil`` ``seriesFrontier`` should be emitted. 2. In the interests of aiding debugging, the raw LevelDB ``levigoIterator`` type now includes a helpful forensics ``String()`` method. This work produced additional cleanups: 1. ``Close() error`` with the storage stack is technically incorrect, since nowhere in the bowels of it does an error actually occur. The interface has been simplified to remove this for now.	12 years ago
Matt T. Proud	d79c932a8e	Merge pull request #120 from prometheus/feature/storage/compaction Spin up curator run in the tests.	12 years ago
Matt T. Proud	c3e3460ca6	Spin up curator run in the tests. After this commit, we'll need to add validations that it does the desired work, which we presently know that it doesn't.

Matt T. Proud	3e97a3630d	Include nascent curator scaffolding. The curator doesn't do anything yet; rather, this is the type definition including the anciliary testing scaffold. Improve Makefile and Git developer experience. The top-level Makefile was a bit overloaded in terms of generation of assets and their management. This has been offloaded into separate Makefiles. The Git developer experience sucked due to lack of .gitignore policies. Also: Fix faulty skiplist naming from old merge.	12 years ago
Matt T. Proud	b2e4c88b80	Wrap LevelDB iterator operations behind interface. The LevelDB storage types return an interface type now that wraps around the underlying iterator. This both enhances testability but improves upon, in my opinion, the interface design for the LevelDB iterator. Secondarily, the resource reaping behaviors for the LevelDB iterators have been improved by dropping the externalized io.Closer object. Finally, the iterator provisioning methods provide the option for indicating whether one wants a snapshotted iterator or not.	12 years ago
