Salva Corts	6cc581bd26	Add back cache stats for index stats requests (#9816 ) What this PR does / why we need it: In https://github.com/grafana/loki/pull/9536, we added cache stats for index stats requests. That PR had a bug that inflated the query stats due to reusing the stats context in the query engine. Therefore, we had to revert the PR at https://github.com/grafana/loki/pull/9721. This PR brings back the changes from https://github.com/grafana/loki/pull/9536 but fixes the inflated starts by no longer reusing the same context in the query engine, but rather creating a new one for the shard resolver. I tested it on a dev cluster and seems to be working fine. here's the output for the same query: Stats with the bug from #9536: ``` ... Cache.StatsResult.Requests 980 Cache.StatsResult.EntriesRequested 490 Cache.StatsResult.EntriesFound 0 Cache.StatsResult.EntriesStored 490 Cache.StatsResult.BytesSent 0 B Cache.StatsResult.BytesReceived 0 B ... Summary.BytesProcessedPerSecond 43 GB Summary.LinesProcessedPerSecond 93305142 Summary.TotalBytesProcessed 945 GB Summary.TotalLinesProcessed 2059694183 ``` Stats from _main_ ``` ...

Summary.BytesProcessedPerSecond 4.3 GB Summary.LinesProcessedPerSecond 9468900 Summary.TotalBytesProcessed 95 GB Summary.TotalLinesProcessed 207793816 ``` As can be seen, with the changes in this PR, the summary stats are no longer inflated. Which issue(s) this PR fixes: Fixes https://github.com/grafana/loki/pull/9536 Special notes for your reviewer: I think it's ok to skip reviewing the changes from the commit cherry-picking the changes from https://github.com/grafana/loki/pull/9536 Checklist - [ ] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (required) - [ ] Documentation added - [ ] Tests updated - [ ] `CHANGELOG.md` updated - [ ] If the change is worth mentioning in the release notes, add `add-to-release-notes` label - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md` - [ ] For Helm chart changes bump the Helm chart version in `production/helm/loki/Chart.yaml` and update `production/helm/loki/CHANGELOG.md` and `production/helm/loki/README.md`.

Travis Patterson	8ca035ffbf	Log Volume: Do the prometheus-format conversion in dedicated middleware (#9776 ) This PR moves the Prometheus-format conversion to it's own middleware. This keeps it all in one place and consolidates logic that was in many places. It also sets us up to make range queries as a next step.	2 years ago
Travis Patterson	4da0f63789	Remove unused Value field (#9774 ) We didn't end up needing the `Value` field because we can express everything we need to as selectors	2 years ago
Trevor Whitney	dbc3040739	Convert SeriesVolume response to prometheus-style (#9703 ) Changes the response type of the label volume stats endpoint to return volumes as prometheus-style timeseries metrics. It currently only supports instant queries, but is a necessary step to eventually supporting range queries.	2 years ago
Salva Corts	b7359c5d53	Revert "Add summary stats and metrics for stats cache (#9536 )" (#9721 ) This reverts commit `af287ac3eb`. There is a bug in this PR that inflates the stats returned for the query since we reuse the stats ctx in the query execution engine.	2 years ago
Travis Patterson	db97058a84	Series volume endpoint (#9704 ) This changes the `label_volume` endpoint to the `series_volume` endpoint. The new endpoint still returns volumes but now it does it for the requested streams defined by the selector names passed rather than individual labels. All relevant non-requested labels are aggregated into the returned results ex: Assume we have the following streams: ``` {cluster="prod", team="A", component="foo"} {cluster="prod", team="B", component="foo"} {cluster="dev", team="A", component="foo"} {cluster="dev", team="B", component="foo"} ``` - requesting `{cluster="prod"}` returns one result for all streams containing `{cluster="prod"}` - requesting `{cluster=~".+"}` returns two results for the streams containing `{cluster="prod"}` and `{cluster="dev"}` - requesting `{cluster=~".+", team=".+"}` returns four results for the streams containing: ``` {cluster="prod", team="A"} {cluster="prod", team="B"} {cluster="dev", team="A"} {cluster="dev", team="B"} ``` --------- Co-authored-by: Trevor Whitney <trevorjwhitney@gmail.com>	2 years ago
Trevor Whitney	4a56445686	Upgrade `golangci-lint` and fix linting errors (#9601 ) What this PR does / why we need it: Upgrade `golangci-lint` and fixes all the errors. The upgrade includes some stricter linting.	2 years ago
Travis Patterson	065bee7e72	Label Volume Endpoint (#9588 ) For a given set of matchers, returns the top N associated label/value pairs by volume. A query for `{cluster=prod}` will return ``` cluster=prod: size (total logs matching this matcher) . . . nth-label=nth-value ``` This is to service use cases where users want to understand where their log volume has come from by label without making multiple requests to the stats endpoint. Note: This PR is a monster but it's mostly plumbing. I've pointed out the most interesting bits that actually get the volumes from ingesters/indexs	2 years ago
Salva Corts	af287ac3eb	Add summary stats and metrics for stats cache (#9536 ) What this PR does / why we need it: When a query finishes, we return (and log) the following stats: ```go Cache.Chunk.Requests 0 Cache.Chunk.EntriesRequested 0 Cache.Chunk.EntriesFound 0 Cache.Chunk.EntriesStored 0 Cache.Chunk.BytesSent 0 B Cache.Chunk.BytesReceived 0 B Cache.Chunk.DownloadTime 0s Cache.Index.Requests 0 Cache.Index.EntriesRequested 0 Cache.Index.EntriesFound 0 Cache.Index.EntriesStored 0 Cache.Index.BytesSent 0 B Cache.Index.BytesReceived 0 B Cache.Index.DownloadTime 0s Cache.Result.Requests 13 Cache.Result.EntriesRequested 13 Cache.Result.EntriesFound 13 Cache.Result.EntriesStored 0 Cache.Result.BytesSent 0 B Cache.Result.BytesReceived 2.5 kB Cache.Result.DownloadTime 4.600266ms ``` In addition to that, we log the following in metrics.go: ``` level=info ts=2023-05-29T09:17:10.93029945Z caller=metrics.go:152 component=frontend org_id=145265 traceID=52d59b78fe6b9221 sampled=true latency=fast query="{cluster=\"dev-us-central-0\", namespace=~\"loki.\", container=~\"distributor\|ingester \|promtail\|index-gateway\|compactor\"} \|= \"thislinewillnotexist\"" query_hash=1194136170 query_type=filter range_type=range length=3h0m0s start_delta=165h37m24.930289434s end_delta=162h37m24.930289612s step=43s duration=2.473055ms status=200 lim it=30 returned_lines=0 throughput=0B total_bytes=0B lines_per_second=0 total_lines=0 total_entries=0 store_chunks_download_time=0s queue_time=0s splits=13 shards=0 cache_chunk_req=0 cache_chunk_hit=0 cache_chunk_bytes_stored=0 cache_chunk_bytes _fetched=0 cache_chunk_download_time=0s cache_index_req=0 cache_index_hit=0 cache_index_download_time=0s cache_result_req=13 cache_result_hit=13 cache_result_download_time=4.600266ms ``` With the goal of being able to better monitor how the stats cache is performing; this PR adds stats for the index stats cache, similarly to how it's done for the results cache. Here's an example of the new stats being returned and printed: ```go ... Cache.StatsResult.Requests 180 Cache.StatsResult.EntriesRequested 129 Cache.StatsResult.EntriesFound 129 Cache.StatsResult.EntriesStored 51 Cache.StatsResult.BytesSent 0 B Cache.StatsResult.BytesReceived 75 kB ... ``` And the new stats from metrics.go ``` ... caller=metrics.go:155 ... cache_stats_results_req=129 cache_stats_results_hit=129 cache_stats_results_download_ti me=156.864429ms ... ``` Special notes for your reviewer: - Blocked by https://github.com/grafana/loki/pull/9535 - Note the new`stats.GetOrCreateContext` func. It's used inside the `query.Exec` method so we don't overwrite the stats added in the stats middleware.

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.
