beorn7	c954cd9d1d	Move packages out of deprecated pkg directory This creates a new `model` directory and moves all data-model related packages over there: exemplar labels relabel rulefmt textparse timestamp value All the others are more or less utilities and have been moved to `util`: gate logging modetimevfs pool runtime Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago
Bjoern Rabenstein	006b5517e2	Simplify makefiles. This removes the dependancy on C leveldb and snappy. It also takes care of fewer dependencies as they would anyway not work on any non-Debian, non-Brew system. Change-Id: Ia70dce1ba8a816a003587927e0b3a3f8ad2fd28c	10 years ago
Julius Volz	ae30453214	Add label names -> label values index. Change-Id: Ie39b4044558afc4d1aa937de7dcf8df61f821fb4	11 years ago
Julius Volz	1eee448bc1	Store samples in custom binary encoding. This has been shown to provide immense decoding speed benefits. See also: https://groups.google.com/forum/#!topic/prometheus-developers/FeGl_qzGrYs Change-Id: I7d45b4650e44ddecaa91dad9d7fdb3cd0b9f15fe	11 years ago

Julius Volz	0226d1ac7a	Implement alerts dashboard and expression console links.	12 years ago
Matt T. Proud	f895acb9ef	Trailing build system cleanups. The .gitignore files had problems, and the build steps could be simplified.	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	dcfd09c801	Prepend "exporter_" to labels that already exist in exported metrics. If the metrics exported by a process already contain any of a target's base labels (such as "job" or "instance", but also any manually assigned target-group label), don't overwrite that label, but instead add a new label consisting of the original label name prepended with "exporter_". This is to accomodate intermediate exporter jobs, which might indicate e.g. the jobs and instances for which they are exporting data.	12 years ago
Julius Volz	5b105c77fc	Repointerize fingerprints.	12 years ago
Julius Volz	259a0ea467	Optimize fingerprint comparison time.	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	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	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 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
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
Bernerd Schaefer	b04cd28862	Merge pull request #192 from prometheus/feature/negotiate-telemetry-schema-through-mime-type Use Content-Type data for telemetry versioning	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

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
juliusv	af7ddc36e2	Merge pull request #176 from prometheus/optimization/view-materialization/slice-chunking Truncate irrelevant chunk values.	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

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	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	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
