beorn7	2d233cf95e	Histogram: Fix allFloatBucketIterator If the zero threshold overlaps with the highest negative bucket and/or the lowest positive bucket, its upper or lower boundary, respectively, has to be adjusted. In valid histograms, only ever the highest negative bucket and/or the lowest positive bucket may overlap with the zero bucket. This is assumed in this code to simplify the checks.

Björn Rabenstein	0e1b9dd308	Promql: Initial rate implementation for sparse histograms (#9926 ) Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago
Björn Rabenstein	7e42acd3b1	tsdb: Rework iterators (#9877 ) - Pick At... method via return value of Next/Seek. - Do not clobber returned buckets. - Add partial FloatHistogram suppert. Note that the promql package is now _only_ dealing with FloatHistograms, following the idea that PromQL only knows float values. As a byproduct, I have removed the histogramSeries metric. In my understanding, series can have both float and histogram samples, so that metric doesn't make sense anymore. As another byproduct, I have converged the sampleBuf and the histogramSampleBuf in memSeries into one. The sample type stored in the sampleBuf has been extended to also contain histograms even before this commit. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago

beorn7	7a8bb8222c	Style cleanup of all the changes in sparsehistogram so far A lot of this code was hacked together, literally during a hackathon. This commit intends not to change the code substantially, but just make the code obey the usual style practices. A (possibly incomplete) list of areas: * Generally address linter warnings. * The `pgk` directory is deprecated as per dev-summit. No new packages should be added to it. I moved the new `pkg/histogram` package to `model` anticipating what's proposed in #9478. * Make the naming of the Sparse Histogram more consistent. Including abbreviations, there were just too many names for it: SparseHistogram, Histogram, Histo, hist, his, shs, h. The idea is to call it "Histogram" in general. Only add "Sparse" if it is needed to avoid confusion with conventional Histograms (which is rare because the TSDB really has no notion of conventional Histograms). Use abbreviations only in local scope, and then really abbreviate (not just removing three out of seven letters like in "Histo"). This is in the spirit of https://github.com/golang/go/wiki/CodeReviewComments#variable-names * Several other minor name changes. * A lot of formatting of doc comments. For one, following https://github.com/golang/go/wiki/CodeReviewComments#comment-sentences , but also layout question, anticipating how things will look like when rendered by `godoc` (even where `godoc` doesn't render them right now because they are for unexported types or not a doc comment at all but just a normal code comment - consistency is queen!). * Re-enabled `TestQueryLog` and `TestEndopints` (they pass now, leaving them disabled was presumably an oversight). * Bucket iterator for histogram.Histogram is now created with a method. * HistogramChunk.iterator now allows iterator recycling. (I think @dieterbe only commented it out because he was confused by the question in the comment.) * HistogramAppender.Append panics now because we decided to treat staleness marker differently.

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

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.

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	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

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
