Poyzan	de83ae0fc7	Update Helm chart docs and yaml (#11800) ... **What this PR does / why we need it**: Following recent loki `v2.9.4` and GEL `v1.8.6` patch releases, updates Helm chart docs and yaml. Loki release drone creates is the [PR as expected](https://github.com/grafana/loki/pull/11769/files), but there seems to be a problem with the GEL drone generating the docs -which is looked at separately. Instead I manually updated them in one go.	2 years ago

George Wilson	1002ba00df	Note the helm chart and docs do not agree (#11782) ... **What this PR does / why we need it**: Docs do not match the code in the helm chart - where the read deployment is made as a statefulset with ReadWriteOnce disks (https://github.com/grafana/loki/blob/main/production/helm/loki/templates/read/statefulset-read.yaml).

Sandeep Sukhani	e625d7f1ca	otel: add support for per tenant configuration for mapping otlp data to loki format (#11143) ... **What this PR does / why we need it**: In OTEL, we pick select Resource Attributes to identify the streams and store all the other attributes as Structured Metadata, as explained here. The problem however is that the list of Resource Attributes that are picked as Stream labels are hardcoded, and there is no way to drop unwanted data. This PR adds support for configuring how data is mapped from OTEL to Loki format per tenant. It also adds support for dropping unwanted data. We decided to make the config look similar to Prometheus's relabling config to make it familiar. **Special notes for your reviewer**: Opening a draft PR to get some initial feedback. I will add documentation in a separate PR. **Checklist** - [x] Tests updated - [x] `CHANGELOG.md` updated	2 years ago

Ashwanth	51899b521b	feat(metadata cache): adds max_metadata_cache_freshness (#11682) ... **What this PR does / why we need it**: Adds `max_metadata_cache_freshness` to limit the metadata requests that get cached. When configured, only metadata requests with end time before `now - max_metadata_cache_freshness` are cacheable. _reason for setting the default to 24h?_ metric results cache can [extract samples for the desired time range from an extent](b6e64e1ef1/pkg/querier/queryrange/queryrangebase/results_cache.go (L78)) since the samples are associated with a timestamp. But the same is not true for metadata caching, it is not possible to extract a subset of labels/series from a cached extent. As a result, we could return inaccurate results, more that what was requested. for ex: returning results from an entire 1h extent for a 5m query Setting `max_metadata_cache_freshness` to 24h should help us avoid caching recent data. For anything older, we would report cached metadata results at a granularity controlled by `split_metadata_queries_by_interval` **Which issue(s) this PR fixes**: Fixes #<issue number> **Special notes for your reviewer**: **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [x] Documentation added - [x] 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/setup/upgrade/_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`.

Danny Kopping	bcd03150c9	Query-frontend: customisable query splitting for queries overlapping `query_ingester_within` window (#11535) ... **What this PR does / why we need it**: The config option `query_ingesters_within` defines the window during which logs _could_ be present on ingesters, and as such queriers will send queries to ingesters instead. `split_queries_by_interval` is defined to split queries into subqueries for increased parallelism. Aggressive query splitting within the `query_ingesters_within` window can result in overloading ingesters with unnecessarily large numbers of subqueries, which perversely can impact writes. `query_ingesters_within` is set to 3h by default. In Grafana Cloud Logs we set `split_queries_by_interval` as low as 15m (defaults to 1h), which would result in result in 3*60/15=12 requests. Every querier queries every ingester during this window, so that's 12 requests _per ingester per query_ which has the `query_ingesters_within` window in its time range _(i.e. a query from now to now-7d would include the `query_ingesters_within` window as well, now-3h to now-7d would not)_. However, we _do_ want to split queries so an ingester won't have to handle a query for a full `query_ingesters_within` window - this could involve a large amount of data. To account for this, this PR introduces a new option `split_ingester_queries_by_interval` on the query-frontend; this setting is disabled by default. 	2 years ago

Poyzan	599eed7c52	[bloom-compactor] remove BloomCompactorMinTableAge check (#11546) ... **What this PR does / why we need it**: `BloomCompactorMinTableAge` was added with the idea that we will skip most recent index files from ingesters that are not compacted into TSDB indexes yet.

We can either reduce it something lower than the frequency of TSDB indexes being built (< 15mins). Here I choose to remove it altogether, assuming uncompacted indexes from ingesters will not be processed as a table as there won't be a schema for that table with the [check here](https://github.com/grafana/loki/blob/main/pkg/bloomcompactor/bloomcompactor.go#L268-L272).	2 years ago

Vladyslav Diachenko	9b691904ef	BloomShipper: add cache for downloaded blocks (#11394) ... adapted embeddedcache.go to store downloaded bloom blocks on local filesystem. **What this PR does / why we need it**: This cache will be used by bloom-gateway to not download the blocks each time. In the cache we store the objects(`cachedBlock` struct) that contain: 1. `blockDirectory`: the `path` to the directory where the block was extracted 2. `activeQueriers`: thread-safe counter of active block users. This field is important because we do not want the directory to be removed while it's in use. 3. rest fields are needed for service needs When the downloadingWorker receives this entity, it increases the counter `activeQueriers` and creates blockQuerier wrapper that has `Close` function that will decrease the counter once blockQuerier is not needed anymore. When the cache entry is being removed from the cache, the cache calls the function `removeDirectoryAsync` which asynchronously removes the block's folder. This function checks every `Xms` if there are still active block queriers and once `activeQueriers` count is `0` the folder will be removed. Also, there is a timeout in this function, and once the timeout is reached, the folder will be force removed. **Special notes for your reviewer**: * If the cache is disabled, then the blocks will be downloaded each time the block is requested. * If the cache is used, the folder will be deleted by embeddedCache when it reaches memory size limit or items count limit. Otherwise, the block's folder will be deleted when `Close` function is called. **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [x] Documentation added - [x] 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/setup/upgrade/_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`.

Ashwanth	d9f3bf30b1	config: adds `frontend.max-query-capacity` to tune per-tenant query capacity (#11284) ... **What this PR does / why we need it**: Adds a new config `frontend.max-query-capacity` that allows users to configure what portion of the the available querier replicas can be used by a tenant. `max_query_capacity` is the corresponding YAML option that can be configured in limits or runtime overrides. For example, setting this to 0.5 would allow a tenant to use half of the available queriers. This complements the existing `frontend.max-queriers-per-tenant`. When both are configured, the smaller value of the resulting querier replica count is considered: ``` min(frontend.max-queriers-per-tenant, ceil(querier_replicas * frontend.max-query-capacity)) ``` *All* queriers will handle requests for a tenant if neither limits are applied. **Which issue(s) this PR fixes**: Fixes #<issue number> **Special notes for your reviewer**: noticed that we don't pass down the shuffle sharding limits for frontend (only using it with schedulers) 26f097162a/pkg/loki/modules.go (L895) but the [docs](26f097162a/pkg/validation/limits.go (L276)) mention that`frontend.max-queriers-per-tenant` applies to frontend as well. ``` This option only works with queriers connecting to the query-frontend / query-scheduler, not when using downstream URL. ``` **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [x] Documentation added - [x] Tests updated - [x] `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/setup/upgrade/_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`.

Salva Corts	67ecf5007b	Make Blooms-Gateway queue settings configurable (#11321) ... **What this PR does / why we need it**: This PR adds three new settings to the Bloom-Gateway config: - `worker_concurrency`: replaces the `numWorkers` constant. Named after the scheduler's `scheduler_worker_concurrency` config. - `max_outstanding_per_tenant`: replaces the `maxTasksPerTenant` constant. Named after the frontend's `max_outstanding_per_tenant` config. - `pending_tasks_initial_capacity`: replaces the pendingTasksInitialCap constant. **Note to the reviewers:** - I think in the future `max_outstanding_per_tenant` should be configurable per-tenant. This would require refactoring the queue pkg and the frontend/scheduler, so I think it doesn't make sense it in this PR. - I moved the `Limits` struct definition to `config.go` so have all the adjustable settings in the same place.	2 years ago
