Nicolás Pazos	aa3513fc89	remote write 2.0: sync with `main` branch (#13510 ) * consoles: exclude iowait and steal from CPU Utilisation 'iowait' and 'steal' indicate specific idle/wait states, which shouldn't be counted into CPU Utilisation. Also see https://github.com/prometheus-operator/kube-prometheus/pull/796 and https://github.com/kubernetes-monitoring/kubernetes-mixin/pull/667. Per the iostat man page: %idle Show the percentage of time that the CPU or CPUs were idle and the system did not have an outstanding disk I/O request. %iowait Show the percentage of time that the CPU or CPUs were idle during which the system had an outstanding disk I/O request. %steal Show the percentage of time spent in involuntary wait by the virtual CPU or CPUs while the hypervisor was servicing another virtual processor.

Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * tsdb: create isolation transaction slice on demand When Prometheus restarts it creates every series read in from the WAL, but many of those series will be finished, and never receive any more samples. By defering allocation of the txRing slice to when it is first needed, we save 32 bytes per stale series.

Use `armnetwork.InterfacesClient.GetVirtualMachineScaleSetNetworkInterface()` instead. This needs both the scale set name and the instance ID, so add an `InstanceID` field to the `virtualMachine` struct. `InstanceID` is empty for a VM that isn't a ScaleSetVM.

The loop ran indefinitely if the condition isn't met. Before, each iteration created a new timer channel which was always outpaced by the other timer channel with smaller duration. minor detail: There was a memory leak: resources of the ~10 previous timers were constantly kept. With the fix, we may keep the resources of one timer around for defaultWait but this isn't worth the changes to make it right.

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.

So let's put this into MAINTAINERS.md. In addition, I hereby proposose George Krajcsovits AKA Krajo as a co-maintainer. He has contributed a lot of native histogram code, but more importantly, he has contributed substantially to reviewing other contributors' native histogram code, up to a point where I was merely rubberstamping the PRs he had already reviewed. 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.

Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Fix last_over_time for native histograms The last_over_time retains a histogram sample without making a copy. This sample is now coming from the buffered iterator used for windowing functions, and can be reused for reading subsequent samples as the iterator progresses. I would propose copying the sample in the last_over_time function, similar to how it is done for rate, sum_over_time and others.

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>	1 year ago

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

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>	2 years ago
beorn7	630bcb494b	storage: Use separate sample types for histogram vs. float Previously, we had one “polymorphous” `sample` type in the `storage` package. This commit breaks it up into `fSample`, `hSample`, and `fhSample`, each still implementing the `tsdbutil.Sample` interface. This reduces allocations in `sampleRing.Add` but inflicts the penalty of the interface wrapper, which makes things worse in total. This commit therefore just demonstrates the step taken. The next commit will tackle the interface overhead problem. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago

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.

Bartlomiej Plotka	d5c33877f9	storage: Added Chunks{Queryable/Querier/SeriesSet/Series/Iteratable. Added generic Merge{SeriesSet/Querier} implementation. (#7005 ) * storage: Added Chunks{Queryable/Querier/SeriesSet/Series/Iteratable. Added generic Merge{SeriesSet/Querier} implementation. ## Rationales: In many places (e.g. chunk Remote read, Thanos Receive fetching chunk from TSDB), we operate on encoded chunks not samples. This means that we unnecessary decode/encode, wasting CPU, time and memory. This PR adds chunk iterator interfaces and makes the merge code to be reused between both seriesSets I will make the use of it in following PR inside tsdb itself. For now fanout implements it and mergers. All merges now also allows passing series mergers. This opens doors for custom deduplications other than TSDB vertical ones (e.g. offline one we have in Thanos). ## Changes * Added Chunk versions of all iterating methods. It all starts in Querier/ChunkQuerier. The plan is that Storage will implement both chunked and samples. * Added Seek to chunks.Iterator interface for iterating over chunks. * NewMergeChunkQuerier was added; Both this and NewMergeQuerier are now using generigMergeQuerier to share the code. Generic code was added. * Improved tests. * Added some TODO for further simplifications in next PRs. Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com> * Addressed Brian's comments.

All imports that. * querier.SeriesIterator replaced by chunkenc.Iterator * Added chunkenc.Iterator.Seek method and tests for xor implementation (?) * Since we properly handle SelectParams for Select methods I adjusted min max based on that. This should help in terms of performance for queries with functions like offset. * added Seek to deletedIterator and test. * storage/tsdb was removed as it was only a unnecessary glue with incompatible structs.
