When checking for cache entries though, we used p.Series() as the key, which included the metric name _with_ its labels. That meant that we were never actually hitting the cache. We're fixing this by utiling the __name__ internal label for correctly getting the cache entries after they've been set by setHelp(), setType() or setUnit().

Dieter Plaetinck	cda025b5b5	TSDB: demistify SeriesRefs and ChunkRefs (#9536 ) * TSDB: demistify seriesRefs and ChunkRefs The TSDB package contains many types of series and chunk references, all shrouded in uint types. Often the same uint value may actually mean one of different types, in non-obvious ways. This PR aims to clarify the code and help navigating to relevant docs, usage, etc much quicker. Concretely: * Use appropriately named types and document their semantics and relations. * Make multiplexing and demuxing of types explicit (on the boundaries between concrete implementations and generic interfaces). * Casting between different types should be free. None of the changes should have any impact on how the code runs.

Robert Fratto	bc72a718c4	Initial draft of prometheus-agent (#8785 ) * Initial draft of prometheus-agent This commit introduces a new binary, prometheus-agent, based on the Grafana Agent code. It runs a WAL-only version of prometheus without the TSDB, alerting, or rule evaluations. It is intended to be used to remote_write to Prometheus or another remote_write receiver. By default, prometheus-agent will listen on port 9095 to not collide with the prometheus default of 9090. Truncation of the WAL cooperates on a best-effort case with Remote Write. Every time the WAL is truncated, the minimum timestamp of data to truncate is determined by the lowest sent timestamp of all samples across all remote_write endpoints. This gives loose guarantees that data from the WAL will not try to be removed until the maximum sample lifetime passes or remote_write starts functionining.

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.

Bartlomiej Plotka	b788986717	storage: Adjusted fully storage layer support for chunk iterators: Remote read client, readyStorage, fanout. (#7059 ) * Fixed nits introduced by https://github.com/prometheus/prometheus/pull/7334 * Added ChunkQueryable implementation to fanout and readyStorage. * Added more comments. * Changed NewVerticalChunkSeriesMerger to CompactingChunkSeriesMerger, removed tiny interface by reusing VerticalSeriesMergeFunc for overlapping algorithm for both chunks and series, for both querying and compacting (!) + made sure duplicates are merged. * Added ErrChunkSeriesSet * Added Samples interface for seamless []promb.Sample to []tsdbutil.Sample conversion. * Deprecating non chunks serieset based StreamChunkedReadResponses, added chunk one. * Improved tests. * Split remote client into Write (old storage) and read. * Queryable client is now SampleAndChunkQueryable. Since we cannot use nice QueryableFunc I moved all config based options to sampleAndChunkQueryableClient to aboid boilerplate. In next commit: Changes for TSDB.

Chris Marchbanks	dfad1da296	Remove duplicate metrics in QueueManager Right now any new metrics added for remote write need to be added to both the QueueManager struct, and the queueManagerMetrics struct. Instead, use the queueManagerMetrics struct directly from QueueManager. The newQueueManagerMetrics constructor will now create the metrics for a specific queue with name and endpoint pre-populated, and a new copy of the struct will be created specifically for each queue. This also fixes a bug where prometheus_remote_storage_sent_bytes_total is not being unregistered after a queue is changed. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>	6 years ago
