beorn7	17443d288b	Avoid copying of the COWMetric if we already have the metric available.	10 years ago
beorn7	9e7c3e3bcd	Add the histogram_quantile function. Since we are now getting really deep into floating point calculation, the tests had to take into account the precision loss. Since the rule tests are based on direct line matching in the output, implementing the "almost equal" semantics was pretty cumbersome, but here we are.	10 years ago

Julius Volz	2dd70b8c13	Merge pull request #542 from prometheus/I-cant-believe-its-not-federation Proof of concept for federation via console templates.	10 years ago
Brian Brazil	5adcec3018	Proof of concept for federation via console templates. This exposes samples via the console templates in the text exposition format, which the parser will fall back to. This is not a proper federation solution, but should tide us over for now. Extenions could include passing in a query or queries in the url parameters.	10 years ago

Julius Volz	67e20acc6c	Lower-case some package-internal names.	10 years ago
Julius Volz	72d7b325a1	Implement offset operator. This allows changing the time offset for individual instant and range vectors in a query. For example, this returns the value of `foo` 5 minutes in the past relative to the current query evaluation time: foo offset 5m Note that the `offset` modifier always needs to follow the selector immediately. I.e. the following would be correct: sum(foo offset 5m) // GOOD. While the following would be incorrect: sum(foo) offset 5m // INVALID. The same works for range vectors. This returns the 5-minutes-rate that `foo` had a week ago: rate(foo[5m] offset 1w) This change touches the following components: * Lexer/parser: additions to correctly parse the new `offset`/`OFFSET` keyword. * AST: vector and matrix nodes now have an additional `offset` field. This is used during their evaluation to adjust query and result times appropriately. * Query analyzer: now works on separate sets of ranges and instants per offset. Isolating different offsets from each other completely in this way keeps the preloading code relatively simple. No storage engine changes were needed by this change. The rules tests have been changed to not probe the internal implementation details of the query analyzer anymore (how many instants and ranges have been preloaded). This would also become too cumbersome to test with the new model, and measuring the result of the query should be sufficient.

Julius Volz	b0c8b56603	Merge pull request #527 from prometheus/nogodep-build Copy vendored deps manually instead of using Godeps.	10 years ago
beorn7	af91fb8e31	Improve persisting chunks to disk. This is done by bucketing chunks by fingerprint. If the persisting to disk falls behind, more and more chunks are in the queue. As soon as there are "double hits", we will now persist both chunks in one go, doubling the disk throughput (assuming it is limited by disk seeks). Should even more pile up so that we end wit "triple hits", we will persist those first, and so on. Even if we have millions of time series, this will still help, assuming not all of them are growing with the same speed. Series that get many samples and/or are not very compressable will accumulate chunks faster, and they will soon get double- or triple-writes. To improve the chance of double writes, -storage.local.persistence-queue-capacity could be set to a higher value. However, that will slow down shutdown a lot (as the queue has to be worked through). So we leave it to the user to set it to a really high value. A more fundamental solution would be to checkpoint not only head chunks, but also chunks still in the persist queue. That would be quite complicated for a rather limited use-case (running many time series with high ingestion rate on slow spinning disks).	10 years ago
Julius Volz	13048b7468	Simplify GOPATH/dependency setup.	10 years ago
Julius Volz	464524fa44	Make config/Makefile use user Go installation. Otherwise it will fail to "go get" the "github.com/golang/protobuf" package because its dir already exists in the vendored packages, but the copy isn't a git repository.	10 years ago

Julius Volz	740a99a9ac	Remove Google Code files, add GitHub files for protobuf lib.	10 years ago
Julius Volz	af627bb2b9	Copy vendored deps manually instead of using Godeps. We were using Godep incorrectly (cloning repos from the internet during build time instead of including Godeps/_workspace in the GOPATH via "godep go"). However, to avoid even having to fetch "godeps" from the internet during build, this now just copies the vendored files into the GOPATH. Also, the protocol buffer library moved from Google Code to GitHub, which is reflected in these updates. This fixes https://github.com/prometheus/prometheus/issues/525	10 years ago

Björn Rabenstein	498e1b5154	Merge pull request #524 from prometheus/beorn7/ingestion-tweaks Improve performance of ingestion.	10 years ago
beorn7	e22f26bc58	Move to a queue model for appending samples after all. Starting a goroutine takes 1-2µs on my laptop. From the "numbers every Go programmer should know", I had 300ns for a channel send in my mind. Turns out, on my laptop, it takes only 60ns. That's fast enough to warrant the machinery of yet another channel with a fixed set of worker goroutines feeding from it. The number chosen (8 for now) is low enough to not really afflict a measurable overhead (a big Prometheus server has >1000 goroutines running), but high enough to not make sample ingestion a bottleneck.	10 years ago

beorn7	5d3cd65a5d	Improve performance of ingestion. - Parallelize AppendSamples as much as possible without breaking the contract about temporal order. - Allocate more fingerprint locker slots. - Do not run early checkpoints if we are behind on chunk persistence. - Increase fpMinWaitDuration to give the disk more time for more important things. Also, switch math.MaxInt64 and math.MinInt64 to the new constants.	10 years ago

juliusv	fd9ee9b009	Merge pull request #518 from prometheus/beorn7/ingestion-tweaks Next try to deal with backed-up ingestion.	10 years ago
beorn7	11b3c2387c	Improvements after review. - Increase samplesQueueCapacity. - Improve docstring for the above. - Accept a short waiting period for the ingest channel to become ready. This should depend on the http timeout, but 100ms is probably good enough to cushion bursts bigger than samplesQueueCapacity, while it is unlikely that anybody ever will set an HTTP timeout similarly short.	10 years ago
beorn7	0f191629c6	Next try to deal with backed-up ingestion. This is now not even trying to throttle in a benign way, but creates a fully-fledged error. Advantage: It shows up very visible on the status page. Disadvantage: The server does not really adjusts to a lower scraping rate. However, if your ingestion backs up, you are in a very irregulare state, I'd say it _should_ be considered an error and not dealt with in a more graceful way. In different news: I'll work on optimizing ingestion so that we will not as easily run into that situation in the first place.	10 years ago
