Gregor Zeitlinger	f01718262a	Unit tests for native histograms (#12668 ) promql: Extend testing framework to support native histograms This includes both the internal testing framework as well as the rules unit test feature of promtool. This also adds a bunch of basic tests. Many of the code level tests can now be converted to tests within the framework, and more tests can be added easily. --------- Signed-off-by: Harold Dost <h.dost@criteo.com> Signed-off-by: Gregor Zeitlinger <gregor.zeitlinger@grafana.com> Signed-off-by: Stephen Lang <stephen.lang@grafana.com> Co-authored-by: Harold Dost <h.dost@criteo.com> Co-authored-by: Stephen Lang <stephen.lang@grafana.com> Co-authored-by: Gregor Zeitlinger <gregor.zeitlinger@grafana.com>	1 year ago

Justin Lei	8ef7dfdeeb	Add a chunk size limit in bytes (#12054 ) Add a chunk size limit in bytes This creates a hard cap for XOR chunks of 1024 bytes. The limit for histogram chunk is also 1024 bytes, but it is a soft limit as a histogram has a dynamic size, and even a single one could be larger than 1024 bytes. This also avoids cutting new histogram chunks if the existing chunk has fewer than 10 histograms yet. In that way, we are accepting "jumbo chunks" in order to have at least 10 histograms in a chunk, allowing compression to kick in. Signed-off-by: Justin Lei <justin.lei@grafana.com>	1 year ago

beorn7	aa82fe198f	tsdb: Fix histogram validation So far, `ValidateHistogram` would not detect if the count did not include the count in the zero bucket. This commit fixes the problem and updates all the tests that have been undetected offenders so far. Note that this problem would only ever create false negatives, so we never falsely rejected to store a histogram because of it. On the other hand, `ValidateFloatHistogram` has been to strict with the count being at least as large as the sum of the counts in all the buckets. Float precision issues could create false positives here, see products of PromQL evaluations, it's actually quite hard to put an upper limit no the floating point imprecision. Users could produce the weirdest expressions, maxing out float precision problems. Therefore, this commit simply removes that particular check from `ValidateFloatHistogram`.

beorn7	65ccf4460a	textparse: Fix endless loop #12731 PR #12557 introduced the possibility of parsing multiple exemplars per native histograms. It did so by requiring the `Exemplar` method of the parser to be called repeatedly until it returns false. However, the protobuf parser code wasn't correctly updated for the old case of a single exemplar for a classic bucket (if actually parsed as a classic bucket) and a single exemplar on a counter. In those cases, the method would return `true` forever, yielding the same exemplar again and again, leading to an endless loop. With this fix, the state is now tracked and the single exemplar is only returned once. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago

Bryan Boreham	1e3fef6ab0	scraping: limit detail on dropped targets, to save memory (#12647 ) It's possible (quite common on Kubernetes) to have a service discovery return thousands of targets then drop most of them in relabel rules. The main place this data is used is to display in the web UI, where you don't want thousands of lines of display. The new limit is `keep_dropped_targets`, which defaults to 0 for backwards-compatibility. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	1 year ago
