Björn Rabenstein	b8d19543b8	Add histogram validation in remote-read and during reducing resolution (#17561 ) ReduceResolution is currently called before validation during ingestion. This will cause a panic if there are not enough buckets in the histogram. If there are too many buckets, the spurious buckets are ignored, and therefore the error in the input histogram is masked. Furthermore, invalid negative offsets might cause problems, too. Therefore, we need to do some minimal validation in reduceResolution. Fortunately, it is easy and shouldn't slow things down. Sadly, it requires to return errors, which triggers a bunch of code changes. Even here is a bright side, we can get rud of a few panics. (Remember: Don't panic!) In different news, we haven't done a full validation of histograms read via remote-read. This is not so much a security concern (as you can throw off Prometheus easily by feeding it bogus data via remote-read) but more that remote-read sources might be makeshift and could accidentally create invalid histograms. We really don't want to panic in that case. So this commit does not only add a check of the spans and buckets as needed for resolution reduction but also a full validation during remote-read.

György Krajcsovits	6e42da8904	feat(remote): reduce resolution of native histograms on remote read If a sample read through remote read has too high resolution, reduce it to the maximum allowed.

beorn7	747c5ee2b1	Apply analyzer "modernize" to the whole codebase See https://pkg.go.dev/golang.org/x/tools/gopls/internal/analysis/modernize for details. This ran into a few issues (arguably bugs in the modernize tool), which I will fix in the next commit, so that we have transparency what was done automatically. Beyond those hiccups, I believe all the changes applied are legitimate. Even where there might be no tangible direct gain, I would argue it's still better to use the "modern" way to avoid micro discussions in tiny style PRs later.

TJ Hoplock	6ebfbd2d54	chore!: adopt log/slog, remove go-kit/log For: #14355 This commit updates Prometheus to adopt stdlib's log/slog package in favor of go-kit/log. As part of converting to use slog, several other related changes are required to get prometheus working, including: - removed unused logging util func `RateLimit()` - forward ported the util/logging/Deduper logging by implementing a small custom slog.Handler that does the deduping before chaining log calls to the underlying real slog.Logger - move some of the json file logging functionality to use prom/common package functionality - refactored some of the new json file logging for scraping - changes to promql.QueryLogger interface to swap out logging methods for relevant slog sugar wrappers - updated lots of tests that used/replicated custom logging functionality, attempting to keep the logical goal of the tests consistent after the transition - added a healthy amount of `if logger == nil { $makeLogger }` type conditional checks amongst various functions where none were provided -- old code that used the go-kit/log.Logger interface had several places where there were nil references when trying to use functions like `With()` to add keyvals on the new *slog.Logger type Signed-off-by: TJ Hoplock <t.hoplock@gmail.com>	1 year ago

In #13215 we allowed an existing object to be reused when converting an integer histogram to a float histogram. This commit follows the same idea and allows injecting an existing object in the AtHistogram and AtFloatHistogram methods. When the injected value is nil, iterators allocate new histograms, otherwise they populate and return the injected object. The commit also adds a CopyTo method to Histogram and FloatHistogram which is used in the BufferedIterator to overwrite items in the ring instead of making new copies. Note that a specialized HPoint pool is needed for all of this to work (`matrixSelectorHPool`). --------- Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com> Co-authored-by: George Krajcsovits <krajorama@users.noreply.github.com> * doc: Mark `mad_over_time` as experimental (#13440) We forgot to do that in https://github.com/prometheus/prometheus/pull/13059 Signed-off-by: beorn7 <beorn@grafana.com> * Change metric label for Puppetdb from 'http' to 'puppetdb' Signed-off-by: Paulin Todev <paulin.todev@gmail.com> * mirror metrics.proto change & generate code Signed-off-by: Ziqi Zhao <zhaoziqi9146@gmail.com> * TestHeadLabelValuesWithMatchers: Add test case (#13414) Add test case to TestHeadLabelValuesWithMatchers, while fixing a couple of typos in other test cases.

I'm confident that he is ready to to be granted commit rights as outlined in the "Maintainers" section of the governance: https://prometheus.io/governance/#maintainers According to the same section of the governance, I will announce the proposed change on the developers mailing list and will give some time for lazy consensus before merging this PR.

In addition to what described in #10420, in this PR I've introduced labels.StableHash(). The idea is to offer an hashing function which doesn't change over time, and that's used by query sharding in order to get a stable behaviour over time. The implementation of labels.StableHash() is the hashing function used by Prometheus before stringlabels, and what's used by Grafana Mimir for query sharding (because built before stringlabels was a thing). Follow up work As mentioned in #10420, if this PR is accepted I'm also open to upload another foundamental piece used by Grafana Mimir query sharding to accelerate the query execution: an optional, configurable and fast in-memory cache for the series hashes.

Filip Petkovski	583f3e587c	Optimize histogram iterators (#13340 ) Optimize histogram iterators Histogram iterators allocate new objects in the AtHistogram and AtFloatHistogram methods, which makes calculating rates over long ranges expensive. In #13215 we allowed an existing object to be reused when converting an integer histogram to a float histogram. This commit follows the same idea and allows injecting an existing object in the AtHistogram and AtFloatHistogram methods. When the injected value is nil, iterators allocate new histograms, otherwise they populate and return the injected object. The commit also adds a CopyTo method to Histogram and FloatHistogram which is used in the BufferedIterator to overwrite items in the ring instead of making new copies. Note that a specialized HPoint pool is needed for all of this to work (`matrixSelectorHPool`). --------- Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com> Co-authored-by: George Krajcsovits <krajorama@users.noreply.github.com>	2 years ago

Bryan Boreham	8065bef172	Move metric type definitions to common/model They are used in multiple repos, so common is a better place for them. Several packages now don't depend on `model/textparse`, e.g. `storage/remote`. Also remove `metadata` struct from `api.go`, since it was identical to a struct in the `metadata` package.

Filip Petkovski	10a82f87fd	Enable reusing memory when converting between histogram types The 'ToFloat' method on integer histograms currently allocates new memory each time it is called.

zenador	69edd8709b	Add warnings (and annotations) to PromQL query results (#12152 ) Return annotations (warnings and infos) from PromQL queries This generalizes the warnings we have already used before (but only for problems with remote read) as "annotations". Annotations can be warnings or infos (the latter could be false positives). We do not treat them different in the API for now and return them all as "warnings". It would be easy to distinguish them and return infos separately, should that appear useful in the future. The new annotations are then used to create a lot of warnings or infos during PromQL evaluations. Partially these are things we have wanted for a long time (e.g. inform the user that they have applied `rate` to a metric that doesn't look like a counter), but the new native histograms have created even more needs for those annotations (e.g. if a query tries to aggregate float numbers with histograms). The annotations added here are not yet complete. A prominent example would be a warning about a range too short for a rate calculation. But such a warnings is more tricky to create with good fidelity and we will tackle it later. Another TODO is to take annotations into account when evaluating recording rules. --------- Signed-off-by: Jeanette Tan <jeanette.tan@grafana.com>	2 years ago

beorn7	c3c7d44d84	lint: Adjust to the lint warnings raised by current versions of golint-ci We haven't updated golint-ci in our CI yet, but this commit prepares for that. There are a lot of new warnings, and it is mostly because the "revive" linter got updated. I agree with most of the new warnings, mostly around not naming unused function parameters (although it is justified in some cases for documentation purposes – while things like mocks are a good example where not naming the parameter is clearer). I'm pretty upset about the "empty block" warning to include `for` loops. It's such a common pattern to do something in the head of the `for` loop and then have an empty block. There is still an open issue about this: https://github.com/mgechev/revive/issues/810 I have disabled "revive" altogether in files where empty blocks are used excessively, and I have made the effort to add individual `// nolint:revive` where empty blocks are used just once or twice. It's borderline noisy, though, but let's go with it for now. I should mention that none of the "empty block" warnings for `for` loop bodies were legitimate.

Charles Korn	0a1de58f7e	Mark Histogram.(Positive\|Negative)Spans as non-nullable. As far as I understand it, we'd never expect to receive a nil span, and remote.spansProtoToSpans would panic if we received a nil span. Marking the fields as non-nullable also means the generated Golang code doesn't use pointers for these fields, reducing allocations. Signed-off-by: Charles Korn <charles.korn@grafana.com>	3 years ago

This commit adds fast paths for this case to several potentially expensive Seek calls. Another bug was in concreteSeriesIterator.Seek.
