Julien Pivotto	7b5507ce4b	Scrape: defer report (#7700 ) When I started wotking on target_limit, scrapeAndReport did not exist yet. Then I simply rebased my work without thinking.

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

Julien Pivotto	8907ba6235	Make TSDB use storage errors This fixes #6992, which was introduced by #6777. There was an intermediate component which translated TSDB errors into storage errors, but that component was deleted and this bug went unnoticed, until we were watching at the Prombench results. Without this, scrape will fail instead of dropping samples or using "Add" when the series have been garbage collected. Signed-off-by: Julien Pivotto <roidelapluie@inuits.eu>	5 years ago
Björn Rabenstein	d80b0810c1	Move crucial actions to defer (#6918 ) With defer having less of a performance penalty, there is no reason not to do those crucial operations via defer. Context: With isolation in place, if we forget to Commit/Rollback, the low watermark will get stuck forever. The current code should not have any bugs, but moving to defer helps to avoid future bugs. This is also moving the `closeAppend` in the `Commit` implementation itself to defer. If logging to the WAL fails, we would have missed the `closeAppend`.

Brian Brazil	5da8990053	Log scrape append failures as debug rather than warn. (#6852 ) This is most likely due to an endpoint not producing valid metrics output, which we should treat the same as a failed scrape, and thus not spam the application logs with it.

Julien Pivotto	ed623f69e2	tsdb: don't allow ingesting empty labelsets (#6891 ) * tsdb: don't allow ingesting empty labelsets When we ingest an empty labelset in the head, further blocks can not be compacted, with the error: ``` level=error ts=2020-02-27T21:26:58.379Z caller=db.go:659 component=tsdb msg="compaction failed" err="persist head block: write compaction: add series: out-of-order series added with label set \"{}\" / prev: \"{}\"" ``` We should therefore reject those invalid empty labelsets upfront. This can be reproduced with the following: ``` cat << END > prometheus.yml scrape_configs: - job_name: 'prometheus' scrape_interval: 1s basic_auth: username: test password: test metric_relabel_configs: - regex: ".*" action: labeldrop static_configs: - targets: - 127.0.1.1:9090 END ./prometheus --storage.tsdb.min-block-duration=1m ``` And wait a few minutes.

Bartlomiej Plotka	34426766d8	Unify Iterator interfaces. All point to storage now. This is part of https://github.com/prometheus/prometheus/pull/5882 that can be done to simplify things. All todos I added will be fixed in follow up PRs. * querier.Querier, querier.Appender, querier.SeriesSet, and querier.Series interfaces merged with storage interface.go. 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. No logic was changed, only different source of abstractions, so no need for benchmarks. Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com>	5 years ago

gotjosh	05842176a6	Make the scrape.metricMetadataStore interface public To test the implementation of our metric metadata API, we need to represent various states of metadata in the scrape metadata store. That is currently not possible as the interface and method to set the store are private. This changes the interface, list and get methods, and the SetMetadaStore function to be public.

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

Fabian Reinartz	ad4c33c1ff	scrape,api: provide per-target metric metadata This adds a per-target cache of scraped metadata. The metadata is only available for the lifecycle of the attached target. An API endpoint allows to select metadata by metric name and a label selection of targets. Signed-off-by: Fabian Reinartz <freinartz@google.com>	7 years ago
