Paul Rogers	14370bb8ce	Revert "Augment statistics.." PR 9400. (#9430 ) What this PR does / why we need it: This PR reverts PR 9400. The data collected within that PR was not sufficient. When queries are done, they are filtered before the merge iterator, resulting in an inability to collect an accurate count of duplicated data. Which issue(s) this PR fixes: Special notes for your reviewer: Checklist - [ ] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (required) - [ ] Documentation added - [ ] Tests updated - [ ] `CHANGELOG.md` updated - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md`	2 years ago
Paul Rogers	1671751cbd	Augment statistics to note how many bytes are in duplicate lines due to replicas (#9400 ) What this PR does / why we need it: This PR is for counting the number of bytes of log lines that were marked as duplicates. This will be utilized to collect better statistics.	2 years ago

Ed Welch	a4eb536fb2	Loki: remove `subqueries` from metrics.go logging and replace it with separate split and shard counters (#8761 ) What this PR does / why we need it: Currently the `metrics.go` log line emitted after every query includes a metric called "subqueries". This currently tracks the number of queries created by the split_by_time operations done in Loki, but does not include any counts for subqueries created as a result of sharding. It becomes difficult to make a single subqueries counter that gives useful information to determine how much a query is split by time and sharded by a shard factor, especially now that sharding in TSDB indexes is dynamic. This PR removes and deprecates the `subqueries` stat and instead creates a `splits` and `shards` statistic which records how much a query was split_by_time and the total number of shards created as well. Which issue(s) this PR fixes: Fixes #<issue number> Special notes for your reviewer: Checklist - [ ] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (required) - [ ] Documentation added - [x] Tests updated - [x] `CHANGELOG.md` updated - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md` --------- Signed-off-by: Edward Welch <edward.welch@grafana.com>	2 years ago

Sandeep Sukhani	89d81020ce	fix lint issues from PR 7804 (#7814 ) What this PR does / why we need it: I had enabled auto-merge in PR #7804, but somehow it still merged the PR without all the checks passing. This PR fixes the failing lint and tests.	3 years ago
Karsten Jeschkies	dd098bbd6d	Return error on JSON serialization error. (#7745 ) Clean up of https://github.com/grafana/loki/pull/7721	3 years ago
Karsten Jeschkies	bd879498ad	Serialize query JSON response in a stream. (#7721 ) What this PR does / why we need it: Previously the query response was converted to `loghttp.ResultValue`. This requires a lot of allocations. Furthermore, the JSON response string was allocated before it was written to the response writer. This changes replaces the conversion from `parser.Value` to `loghttp.ResultValue` with a hand written JSON stream. This redueces the allocation overhead quite a bit: ``` › benchstat before.txt after.txt name old time/op new time/op delta _Encode-16 51.5µs ± 1% 24.1µs ± 5% -53.25% (p=0.008 n=5+5) name old alloc/op new alloc/op delta _Encode-16 7.68kB ± 0% 1.66kB ± 0% -78.34% (p=0.008 n=5+5) name old allocs/op new allocs/op delta _Encode-16 129 ± 0% 28 ± 0% -78.29% (p=0.008 n=5+5) ``` The correctness is validate with quick check.

Cyril Tovena	6aa85e318c	Improves performance of json responses (#7522 ) What this PR does / why we need it: This allows to reuse stream memory allocations between responses. Related https://github.com/grafana/loki/pull/3163 but this time this is for the encoding. ``` ❯ benchstat before.txt after.txt name old time/op new time/op delta _Encode-16 29.2µs ±12% 25.2µs ± 1% -13.85% (p=0.016 n=5+4) name old alloc/op new alloc/op delta _Encode-16 24.9kB ± 6% 16.4kB ± 8% -34.20% (p=0.008 n=5+5) name old allocs/op new allocs/op delta _Encode-16 145 ± 0% 129 ± 0% -11.03% (p=0.008 n=5+5) ```	3 years ago
Danny Kopping	c3e92b876c	Restoring lint checks that were previously disabled (#7340 ) I removed these checks in https://github.com/grafana/loki/pull/7337 to not make https://github.com/grafana/loki/pull/7243 overly complex to review. Refactored code to fix valid lint issues, ignored the irrelevant/dangerous ones. I also removed `unused` and `unparam` as these produce low-quality results that are largely useless.	3 years ago
