Salva Corts	5f7bde74ac	Add limits (#10552 ) What this PR does / why we need it: This PR introduces two new limits for structured metadata: - `max_structured_metadata_size`: Defaults to 64 KB. Limits the maximum size of the structured metadata attached to a log line. - `max_structured_metadata_entries_count`: Default to 128. Limits the maximum number of structured metadata entries attached to a log line. We discussed adding other limits like `max_structured_metadata_label_name_length` and `max_structured_metadata_label_value_length` but discarded this idea for now.	2 years ago

Dylan Guedes	c0d9a2b4ba	Log push failures per-entry instead of in batches (#9720 ) What this PR does / why we need it: Modify how we log push errors to do it per-entry instead of accumulating all errors and then logging them all in a single pass. Which issue(s) this PR fixes: N/A	2 years ago

Ed Welch	fc8c4f0592	Loki: Add a configurable ability to fudge incoming timestamps for guaranteed query sort order when receiving entries for the same stream that have duplicate timestamps.

Kaviraj	564f833a30	Improve error message if incoming logs timestamp is far too behind. (#5040 ) * Improve error message if incoming logs timestamp is far too behind. This is part of JSON response giving out as the response to HTTP /push endpoint. Old message ``` {"code":400,"status":"error","message":"entry for stream '{foo=\"bar\"}' has timestamp too old: 1970-01-01 01:00:00.5 +0100 CET"} ``` New message ``` {"code":400,"status":"error","message":"entry for stream '{foo=\"bar\"}' has timestamp too old: 2021-12-28 01:48:45.5 +0100 CET, accepts timestamp from: 2021-12-29 09:48:45.737756651 +0100 CET"} ``` main rationale being, hard to know what is the closest timestamp that Loki is expecting without going through the config. Also config is not straight forward (its `latest stream's timestamp - ingester.max-chunk-age/2`) Signed-off-by: Kaviraj <kavirajkanagaraj@gmail.com> * Tweaks the error message Signed-off-by: Kaviraj <kavirajkanagaraj@gmail.com> * Fix `distributor/validator_test`. 1.

Travis Patterson	8a2081a39e	Distributor: Truncate rather than drop log lines (#4051 ) * Truncate rather than drop logs - When log lines are longer than maxLineSize, truncate them to maxLineSize rather than dropping them Fixes: #3747 * Review feedback: - Rename 'max_line_size_should_truncate' to 'max_line_size_truncate' - Add configurable truncated indicator - Add Truncated Line metric - Changed truncated metrics to have the name mutated_{samples,bytes}_total * Linter * Review Feedback - Make metric variable names match metric names - Add benchmarks - reduce truncation allocs by 100x * Linter * Remove truncation indicator	4 years ago

Cyril Tovena	2303f1bfa1	Cache label strings in ingester to improve memory usage. (#2926 ) * Add benchmark for base stats. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Cache labels string in ingester to improve memory usage. This reduce allocations by a lot, but assume that labels comes in sorted which is not ensure in the distributors. The distributors will take a performance hit, but that's easier to scale or improve later.(added some todos) see benchmark: ``` ❯ benchcmp before.txt after.txt benchmark old ns/op new ns/op delta Benchmark_PushInstance-16 43505 4950 -88.62% benchmark old allocs new allocs delta Benchmark_PushInstance-16 240 12 -95.00% benchmark old bytes new bytes delta Benchmark_PushInstance-16 42568 1787 -95.80% ``` Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * 🤦 wrong hashing.

Ed Welch	3dfe89369f	Loki: refactor validation and improve error messages (#2021 ) * copies some of the validation logic from cortex and modifies it to appropriate for Loki, this gives us a single metric we can use for detetecting validation errors (previously we had to check cortex_ and loki_ metrics) as well as lets us use error messages more appropriate for logs than metrics.
