Callum Styan 8fd73b1d28 Add Exemplar Remote Write support (#8296 ) * Write exemplars to the WAL and send them over remote write. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Update example for exemplars, print data in a more obvious format. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Add metrics for remote write of exemplars. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Fix incorrect slices passed to send in remote write. Signed-off-by: Callum Styan <callumstyan@gmail.com> * We need to unregister the new metrics. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Address review comments Signed-off-by: Callum Styan <callumstyan@gmail.com> * Order of exemplar append vs write exemplar to WAL needs to change. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Several fixes to prevent sending uninitialized or incorrect samples with an exemplar. Fix dropping exemplar for missing series. 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> * Address some of Ganesh's review comments. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Move exemplar remote write feature flag to a config file field. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Address Bartek's review comments. 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. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Address a few last review comments Signed-off-by: Callum Styan <callumstyan@gmail.com> Co-authored-by: Martin Disibio <mdisibio@gmail.com>		4 years ago
