Goutham	3048a88ae7	Add suffixes Older version already did that. This upgrade needed manual opt-in Signed-off-by: Goutham <gouthamve@gmail.com>	1 year ago
Goutham	a99f48cc9f	Bump OTel Collector dependency to v0.88.0 I initially didn't copy the otlptranslator/prometheus folder because I assumed it wouldn't get changes. But it did. So this PR fixes that and updates the Collector version. Supersedes: https://github.com/prometheus/prometheus/pull/12809 Signed-off-by: Goutham <gouthamve@gmail.com>	1 year ago

beorn7	4696b46dd5	storage: Fix mixed samples handling in sampleRing Two issues are fixed here, that lead to the same problem: 1. If `newSampleRing` is called with an unknown ValueType including ValueNone, we have initialized the interface buffer (`iBuf`). However, we would still use a specialized buffer for the first sample, opportunistically assuming that we might still not encounter mixed samples and we should go down the more efficient road. 2. If the `sampleRing` is `reset`, we leave all buffers alone, including `iBuf`, which is generally fine, but not for `iBuf`, see below. In both cases, `iBuf` already contains values, but we will fill one of the specialized buffers first. Once we then actually encounter mixed samples, the content of the specialized buffer is copied into `iBuf` using `append`. That's by itself the right idea because `iBuf` might be `nil`, and even if not, it might or might not have the right capacity. However, this approach assumes that `iBuf` is empty, or more precisely has a length of zero. This commit makes sure that `iBuf` does not get needlessly initialized in `newSampleRing` and that it is emptied upon `reset`. A test case is added to demonstrate both issues above.

Bryan Boreham	a5a4eab679	Storage: reduce memory allocations when merging series sets (#12938 ) Instead of setting to nil and allocating a new slice every time the merge is advanced, re-use the previous slice. This is safe because the `currentSets` member is only used inside member functions, and explicitly copied in `At()`, the only place it leaves the struct.

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>	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`.
