Björn Rabenstein	7e42acd3b1	tsdb: Rework iterators (#9877 ) - Pick At... method via return value of Next/Seek. - Do not clobber returned buckets. - Add partial FloatHistogram suppert. 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. As another byproduct, I have converged the sampleBuf and the histogramSampleBuf in memSeries into one. The sample type stored in the sampleBuf has been extended to also contain histograms even before this commit. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago

Dieter Plaetinck	cda025b5b5	TSDB: demistify SeriesRefs and ChunkRefs (#9536 ) * TSDB: demistify seriesRefs and ChunkRefs The TSDB package contains many types of series and chunk references, all shrouded in uint types. Often the same uint value may actually mean one of different types, in non-obvious ways. This PR aims to clarify the code and help navigating to relevant docs, usage, etc much quicker. Concretely: * Use appropriately named types and document their semantics and relations. * Make multiplexing and demuxing of types explicit (on the boundaries between concrete implementations and generic interfaces). * Casting between different types should be free. None of the changes should have any impact on how the code runs.

Łukasz Mierzwa	f0a26266c0	Add scrape_sample_limit metric This adds a new metric exposing per target scrape sample_limit value.

beorn7	5de2df752f	Hacky implementation of protobuf parsing This "brings back" protobuf parsing, with the only goal to play with the new sparse histograms. The Prom-2.x style parser is highly adapted to the structure of the Prometheus text format (and later OpenMetrics). Some jumping through hoops is required to feed protobuf into it. This is not meant to be a model for the final implementation. It should just enable sparse histogram ingestion at a reasonable efficiency. Following known shortcomings and flaws: - No tests yet. - Summaries and legacy histograms, i.e. without sparse buckets, are ignored. - Staleness doesn't work (but this could be fixed in the appender, to be discussed). - No tricks have been tried that would be similar to the tricks the text parsers do (like direct pointers into the HTTP response body). That makes things weird here. Tricky optimizations only make sense once the final format is specified, which will almost certainly not be the old protobuf format. (Interestingly, I expect this implementation to be in fact much more efficient than the original protobuf ingestion in Prom-1.x.) - This is using a proto3 version of metrics.proto (mostly to be consistent with the other protobuf uses). However, proto3 sees no difference between an unset field. We depend on that to distinguish between an unset timestamp and the timestamp 0 (1970-01-01, 00:00:00 UTC). In this experimental code, we just assume that timestamp is never specified and therefore a timestamp of 0 always is interpreted as "not set". Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago

Damien Grisonnet	b50f9c1c84	Add label scrape limits (#8777 ) * scrape: add label limits per scrape Add three new limits to the scrape configuration to provide some mechanism to defend against unbound number of labels and excessive label lengths. If any of these limits are broken by a sample from a scrape, the whole scrape will fail. For all of these configuration options, a zero value means no limit. The `label_limit` configuration will provide a mechanism to bound the number of labels per-scrape of a certain sample to a user defined limit. This limit will be tested against the sample labels plus the discovery labels, but it will exclude the __name__ from the count since it is a mandatory Prometheus label to which applying constraints isn't meaningful. The `label_name_length_limit` and `label_value_length_limit` will prevent having labels of excessive lengths. These limits also skip the __name__ label for the same reasons as the `label_limit` option and will also make the scrape fail if any sample has a label name/value length that exceed the predefined limits. Signed-off-by: Damien Grisonnet <dgrisonn@redhat.com> * scrape: add metrics and alert to label limits Add three gauge, one for each label limit to easily access the limit set by a certain scrape target. Also add a counter to count the number of targets that exceeded the label limits and thus were dropped. This is useful for the `PrometheusLabelLimitHit` alert that will notify the users that scraping some targets failed because they had samples exceeding the label limits defined in the scrape configuration. Signed-off-by: Damien Grisonnet <dgrisonn@redhat.com> * scrape: apply label limits to __name__ label Apply limits to the __name__ label that was previously skipped and truncate the label names and values in the error messages as they can be very very long. Signed-off-by: Damien Grisonnet <dgrisonn@redhat.com> * scrape: remove label limits gauges and refactor Remove `prometheus_target_scrape_pool_label_limit`, `prometheus_target_scrape_pool_label_name_length_limit`, and `prometheus_target_scrape_pool_label_value_length_limit` as they are not really useful since we don't have the information on the labels in it.

Tom Wilkie	7369561305	Combine Appender.Add and AddFast into a single Append method. (#8489 ) This moves the label lookup into TSDB, whilst still keeping the cached-ref optimisation for repeated Appends. This makes the API easier to consume and implement. In particular this change is motivated by the scrape-time-aggregation work, which I don't think is possible to implement without it as it needs access to label values.

Bartlomiej Plotka	c4eefd1b3a	storage: Removed SelectSorted method; Simplified interface; Added requirement for remote read to sort response. This is technically BREAKING CHANGE, but it was like this from the beginning: I just notice that we rely in Prometheus on remote read being sorted. This is because we use selected data from remote reads in MergeSeriesSet which rely on sorting. I found during work on https://github.com/prometheus/prometheus/pull/5882 that we do so many repetitions because of this, for not good reason. I think I found a good balance between convenience and readability with just one method. Smaller the interface = better. Also I don't know what TestSelectSorted was testing, but now it's testing sorting. Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com>	5 years ago

xjewer	0d1a69353e	scrape: Add global jitter for HA server (#5181 ) * scrape: Add global jitter for HA server Covers issue in https://github.com/prometheus/prometheus/pull/4926#issuecomment-449039848 where the HA setup become a problem for targets unable to be scraped simultaneously. The new jitter per server relies on the hostname and external labels which necessarily to be uniq. As before, scrape offset will be calculated with regard the absolute time, so even restart/reload doesn't change scrape time per scrape target + prometheus instance. Use fqdn if possible, otherwise fall back to the hostname. It adds extra random seed to calculate server hash to be distinguish on machines with the same hostname, but different DC.

Krasi Georgiev	47a673c3a0	process scrape loops reloading in parallel (#4526 ) The scrape manage receiver's channel now just saves the target sets and another backgorund runner updates the scrape loops every 5 seconds. This is so that the scrape manager doesn't block the receiving channel when it does the long background reloading of the scrape loops. Active and dropped targets are now saved in each scrape pool instead of the scrape manager. This is mainly to avoid races when getting the targets via the web api. When reloading the scrape loops now happens in parallel to speed up the final disared state and this also speeds up the prometheus's shutting down. Also updated some funcs signatures in the web package for consistency. Signed-off-by: Krasi Georgiev <kgeorgie@redhat.com>	6 years ago
