Bryan Boreham	60804c5a09	remote_write: reduce blocking from garbage-collect of series (#9109 ) * Refactor: pass segment-reading function as param To allow a different implementation to be used when garbage-collecting. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * remote_write: reduce blocking from GC of series Add a method `UpdateSeriesSegment()` which is used together with `SeriesReset()` to garbage-collect old series. This allows us to split the lock around queueManager series data and avoid blocking `Append()` while reading series from the last checkpoint. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Cosmetic: review feedback on comments Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * remote-write benchmark: include GC of series Reduce the total number of samples per iteration from 50005000 (25 million) which is too big for my laptop, to 110000. Extend `createTimeseries()` to add additional labels, so that the queue manager is doing more realistic work. Move the Append() call to a background goroutine - this works because TestWriteClient uses a WaitGroup to signal completion. Call `StoreSeries()` and `SeriesReset()` while adding samples, to simulate the garbage-collection that wal.Watcher does.

Add tests for queue_manager sending exemplars Signed-off-by: Martin Disibio <mdisibio@gmail.com> * Store both samples and exemplars in the same timeseries buffer to remove the alloc when building final request, keep sub-slices in separate buffers for re-use Signed-off-by: Martin Disibio <mdisibio@gmail.com> * Condense sample/exemplar delivery tests to parameterized sub-tests Signed-off-by: Martin Disibio <mdisibio@gmail.com> * Rename test methods for clarity now that they also handle exemplars Signed-off-by: Martin Disibio <mdisibio@gmail.com> * Rename counter variable. Fix instances where metrics were not updated correctly Signed-off-by: Martin Disibio <mdisibio@gmail.com> * Add exemplars to LoadWAL benchmark Signed-off-by: Callum Styan <callumstyan@gmail.com> * last exemplars timestamp metric needs to convert value to seconds with ms precision Signed-off-by: Callum Styan <callumstyan@gmail.com> * Process exemplar records in a separate go routine when loading the WAL. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Address review comments related to clarifying comments and variable names. Also refactor sample/exemplar to enqueue prompb types. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Regenerate types proto with comments, update protoc version again. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Put remote write of exemplars behind a feature flag.

Signed-off-by: Callum Styan <callumstyan@gmail.com> * Don't allocate exemplar buffers in queue_manager if we're not going to send exemplars over remote write. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Add ValidateExemplar function, validate exemplars when appending to head and log them all to WAL before adding them to exemplar storage. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Address more reivew comments from Ganesh. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Add exemplar total label length check.

Brian Brazil	073e93c768	Gracefully handle unknown WAL record types. (#8004 ) As we're looking to expand what's in the WAL, having old Prometheus servers ignore the new record types rather than treating them as corruption allows for better upgrade/downgrade paths. Adjust some tests accordingly, so they're still testing what they're meant to test. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	4 years ago

Callum Styan	f802f1e8ca	Fix bug with WAL watcher and Live Reader metrics usage. (#6998 ) * Fix bug with WAL watcher and Live Reader metrics usage. Calling NewXMetrics when creating a Watcher or LiveReader results in a registration error, which we're ignoring, and as a result other than the first Watcher/Reader created, we had no metrics for either. So we would only have metrics like Watcher Records Read for the first remote write config in a users config file. Signed-off-by: Callum Styan <callumstyan@gmail.com>	5 years ago
Brian Brazil	536d416299	Fix tsdb code and tests to work on Windows. (#6547 ) Add back Windows CI, we lost it when tsdb was merged into the prometheus repo.
