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. Make `time.Now()` mockable. 2. Make time format consistent across error messages.

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.
