Bryan Boreham	1e3fef6ab0	scraping: limit detail on dropped targets, to save memory (#12647 ) It's possible (quite common on Kubernetes) to have a service discovery return thousands of targets then drop most of them in relabel rules. The main place this data is used is to display in the web UI, where you don't want thousands of lines of display. The new limit is `keep_dropped_targets`, which defaults to 0 for backwards-compatibility. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago

Oleg Zaytsev	61daa30bb1	Pass ref to SeriesLifecycleCallback.PostDeletion (#12626 ) When a particular SeriesLifecycleCallback tries to optimize and run closer to the Head, keeping track of the HeadSeriesRef instead of the labelsets, it's impossible to handle the PostDeletion callback properly as there's no way to know which series refs were deleted from the head. This changes the callback to provide the series refs alongside the labelsets, so the implementation can choose what to do. Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com>	2 years ago

Łukasz Mierzwa	3c80963e81	Use a linked list for memSeries.headChunk (#11818 ) Currently memSeries holds a single head chunk in-memory and a slice of mmapped chunks. When append() is called on memSeries it might decide that a new headChunk is needed to use for given append() call. If that happens it will first mmap existing head chunk and only after that happens it will create a new empty headChunk and continue appending our sample to it. Since appending samples uses write lock on memSeries no other read or write can happen until any append is completed. When we have an append() that must create a new head chunk the whole memSeries is blocked until mmapping of existing head chunk finishes. Mmapping itself uses a lock as it needs to be serialised, which means that the more chunks to mmap we have the longer each chunk might wait for it to be mmapped. If there's enough chunks that require mmapping some memSeries will be locked for long enough that it will start affecting queries and scrapes. Queries might timeout, since by default they have a 2 minute timeout set. Scrapes will be blocked inside append() call, which means there will be a gap between samples. This will first affect range queries or calls using rate() and such, since the time range requested in the query might have too few samples to calculate anything. To avoid this we need to remove mmapping from append path, since mmapping is blocking. But this means that when we cut a new head chunk we need to keep the old one around, so we can mmap it later. This change makes memSeries.headChunk a linked list, memSeries.headChunk still points to the 'open' head chunk that receives new samples, while older, yet to be mmapped, chunks are linked to it. Mmapping is done on a schedule by iterating all memSeries one by one. Thanks to this we control when mmapping is done, since we trigger it manually, which reduces the risk that it will have to compete for mmap locks with other chunks.

Robert Fratto	886945cda7	tsdb/agent: ensure that new series get written to WAL on rollback (#12592 ) If a new series is introduced in a storage.Appender instance, that series should be written to the WAL once the storage.Appender is closed, even on Rollback. Previously, new series would only be written to the WAL when calling Commit. However, because the series is stored in memory regardless, subsequent calls to Commit may write samples to the WAL which reference a series ID which that was never written. Related to #11589. It's likely that this fix also resolves this issue, but we need more testing from users to see if the problem persists after this fix; there may be more cases where samples get written to the WAL in Prometheus Agent mode without the corresponding series record.

Björn Rabenstein	b1a6d003d1	Merge pull request #12584 from prometheus/beorn7/histogram histogram: Identify native histograms even without observations	2 years ago
beorn7	c58e20ad0e	histogram: Identify native histograms even without observations Native histograms without observations and with a zero threshold of zero look the same as classic histograms in the protobuf exposition format. According to https://github.com/prometheus/client_golang/issues/1127 , the idea is to add a no-op span to those histograms to mark them as native histograms. This commit enables Prometheus to detect that no-op span and adds a doc comment to the proto spec describing the behavior. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
