Matt T. Proud	3b9b1c6ab4	Define dependencies for web. stack concretely. This commit destroys the use of AppState, which makes passing concrete state along to various serving components onerous.	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	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	2202cd71c9	Track alerts over time and write out alert timeseries.	12 years ago
Bernerd Schaefer	dfd5c9ce28	Refactor processor for 0.0.2 schema Primary changes: * Strictly typed unmarshalling of metric values * Schema types are contained by the processor (no "type entity002") Minor changes: * Added ProcessorFunc type for expressing processors as simple functions. * Added non-destructive `Merge` method to `model.LabelSet`	12 years ago
Julius Volz	d4ff85db5a	Add instance label to health (up) timeseries.	12 years ago
Matt T. Proud	9e02c2393a	Include generated Protocol Buffer descriptor. The Protocol Buffer compiler supports generating a machine-readable descriptor file encoded as a provided Protocol Buffer message type, which can be used to decode messages that have been encoded with it after-the-fact. The generated descriptor also bundles in dependent message types. We can use this to perform forensics on old Prometheus clients, if necessary.	12 years ago
Julius Volz	9b8c671ec9	Fixes/cleanups to renderView() samples truncation.	12 years ago
Matt T. Proud	e86f4d9dfd	Convert time readers to represent time in UTC. Go's time.Time represents time as UTC in its fundamental data type. That said, when using ``time.Unix(...)``, it sets the zone for the time representation to the local. Unfortunately with diagnosis and our tests, it is a PITA to jump between various zones, even though the serialized version remains the same. To keep things easy, all places where times are generated or read are converted into UTC. These conversions are cheap, for ``Time.In`` merely changes a pointer reference in the struct, nothing more. This enables me to diagnose test failures with fixture data very easily.	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	b1a8e51b07	Extract dto.SampleValueSeries into model.Values.	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
Julius Volz	99dcbe0f94	Integrate memory and disk layers in view rendering.	12 years ago
Matt T. Proud	32c0a939b0	New self-sustaining, hermetic build system. This should help us produce self-contained artifacts for users as well as lower the hurdles for first-time contributors.	12 years ago

Julius Volz	fd554e8b89	Make LevelDB sample keys fixed-length to ensure correct sort-order.	12 years ago
Julius Volz	ebe05d1b83	Fix logic bug in fingerprint Less() comparison. Seems like just using String() is the easiest way of doing this.	12 years ago
Julius Volz	0230dbf305	Fix off-by-one bug in NewFingerprintFromMetric().	12 years ago

Julius Volz	2b8f0b2cc7	Constantize metric name label name.	12 years ago
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	05a9c3cd0b	Improve the base label representation in /status. The base label representation under /status needs improvement to enhance readability; namely, add sorting and make the label representation concise.	12 years ago
Matt T. Proud	13ae29b304	Initial in-memory arena implementation. It is unbounded, and nothing uses it except for a gating flag in main.	12 years ago
Matt T. Proud	4502b49524	Swap out fingerprinting infrastructure. All old database entries should be deleted. :-(	12 years ago
Matt T. Proud	1c74eedf76	Create initial Metric fingerprinter. The old system relies off of super-careful notion that the serialized form of a Protocol Buffer should be used for fingerprint formulation. Of course this is both wrong and inefficient. This commit breaks ground for swapping to a pure attribute-oriented digest.	12 years ago
Julius Volz	d67e4b9131	Address outstanding comments from PR/47 and other cleanups.	12 years ago
Matt T. Proud	ea54751431	Update import paths to new location. This repository moved from matttproud/prometheus to prometheus/prometheus, and all import paths need to be updated.	12 years ago
