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.

gotjosh	4eca4dffb8	Allow metric metadata to be propagated via Remote Write. (#6815 ) * Introduce a metadata watcher Similarly to the WAL watcher, its purpose is to observe the scrape manager and pull metadata. Then, send it to a remote storage.

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	8b49c9285d	scrape: Add metrics to track bytes and entries in the metadata cache (#6675 ) Signed-off-by: gotjosh <josue@grafana.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. Incidentally, the scrapeCache implementation needs to be renamed to match the new signature. Signed-off-by: gotjosh <josue@grafana.com>	5 years ago

Tariq Ibrahim	8fdfa8abea	refine error handling in prometheus (#5388 ) i) Uses the more idiomatic Wrap and Wrapf methods for creating nested errors. ii) Fixes some incorrect usages of fmt.Errorf where the error messages don't have any formatting directives. iii) Does away with the use of fmt package for errors in favour of pkg/errors Signed-off-by: tariqibrahim <tariq181290@gmail.com>	6 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.
