HTErik	4108aedeea	Promtail Docs: Clarifiy labels and timestamps set by cri stage (#7521) ... Add description that `cri` stage not only adds labels for timestamp, but that it also sets the timestamp of the log-entry before sending it. Honestly I don't know if this is the intention or not, but this is how things are implemented today and it makes the most sense. Even if not, changing the behavior now would not be possible without breaking old implicit assumptions, so better have more explicit documentation. Also clarify that the cri-`flags` get extracted as a label.	3 years ago

Chris Hodges	eb6ba615f4	Promtail: Add configuration to drop batches when rate limited by Loki (#7973) ... This change will allow for more deterministic behavior by multitenant Promtail instances where one or more tenants are being heavily throttled due to limits exceeded within Loki. Specifically, it will reduce the performance impact of having exponential backoff cause HOL blocking for rate limit response codes while other tenants are ready to send batches.

Ashwanth	b3e038c7a8	config_wrapper: Add support for named stores (#7946) ... Signed-off-by: Ashwanth Goli <iamashwanth@gmail.com> **What this PR does / why we need it**: This PR adds support for named stores which allows users to define multiple object store configurations for a storage type. Named stores can be referred to from other sections of the config similar to how provider type is being used `i.e aws, gcs...`. Named store reference should be of the format: `<store_type>.<key_name>` Below is an example configuration with two named stores defined for aws `store-1, store-2`. Schema config is referring to one of them as `aws.store-1` ``` storage_config: aws: endpoint: s3://common-bucket region: us-east1 access_key_id: abc123 secret_access_key: def789 named_stores: aws: store-1: endpoint: s3://foo-bucket region: us-west1 access_key_id: 123abc secret_access_key: 789def store-2: endpoint: s3://bar-bucket region: us-west2 access_key_id: 456def secret_access_key: 789abc schema_config: configs: - from: "2020-07-31" index: period: 24h prefix: loki_prod_index_ object_store: aws.store-1 schema: v11 store: boltdb-shipper ``` **Which issue(s) this PR fixes**: Fixes #7276 **Special notes for your reviewer**: Configuration defined in common storage config has no effect on the named stores. Common storage config only overrides storageConfig if it's not explicitly set - same behavior as before. This should be a non-intrusive change.

Ed Welch	2b66c6b126	Loki: add a 'since' query parameter for easier querying using relative time (#7964) ... Signed-off-by: Edward Welch <edward.welch@grafana.com> **What this PR does / why we need it**: logcli has a command line parameter called `since` which makes it easy to query logs relative to the current time, however this is some syntactic sugar used in logcli to calculate `start` and `end` query parameters for the query sent to Loki. This PR adds native support for a `since` query parameter to make it a little easier to consume the Loki query API without having to calculate precise start/end times with every request. This is useful if you are polling the Loki API from a third party app which doesn't let you easily build dynamic URL's and all you want to do is poll for say the last 3 hours of logs. **Which issue(s) this PR fixes**: Fixes #<issue number> **Special notes for your reviewer**: **Checklist** - [x] Reviewed the `CONTRIBUTING.md` guide - [x] 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> Co-authored-by: Owen Diehl <ow.diehl@gmail.com>	3 years ago

Christian Haudum	17577b4d47	Shut down query frontend gracefully (#7978) ... **What this PR does / why we need it**: This PR fixes a bug in the shutdown process of the query frontend. In order to shut down the frontend gracefully without cancelling any in-flight operations/sub-requests, the frontend service has to wait until all in-flight operations are finished. Only then its sub-services may be stopped. In order to control the deterministic order of the shutdown of the service and its child services, child services need to be started with their own context (not with their parent context). Otherwise, if the context of the frontend is cancelled, also the contexts of the child services are cancelled, leading to a parallel stopping of the parent and its child services. During the time of the shutdown, the `RoundTripGRCP` function still needs to accept any round-tripping requests. This is, because the frontend round tripper is wrapped into a query range tripper ware, which splits incoming (HTTP) query requests into multiple (gRPC) query requests if needed. **Which issue(s) this PR fixes**: This fixes a race condition where queries fail, because the query frontend shut down before the queriers that processed in-flight request could send the query response to the frontend. This manifested in an increased error rate of queries during restarts (rollouts) of the query frontend. **Special notes for your reviewer**: **Checklist** - [x] Reviewed the `CONTRIBUTING.md` guide - [x] 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: Danny Kopping <danny.kopping@grafana.com> Signed-off-by: Christian Haudum <christian.haudum@gmail.com> Co-authored-by: Danny Kopping <danny.kopping@grafana.com>	3 years ago

Sandeep Sukhani	9e7ac3d853	fix query-frontend request load balancing when using k8s service (#7966) ... **What this PR does / why we need it**: We noticed an imbalance in the requests sent to the Query Frontend pods using `query-frontend` k8s service. This seems to be caused by `query-frontend` being a headless service that resolves to each QF pod IP and leaves it up to the client to load balance the requests as mentioned [here](https://kubernetes.io/docs/concepts/services-networking/service/#headless-services). This PR fixes the issue by creating two separate services for pod IP discovery and load balancing of queries: * `query-frontend` to be used for load balancing incoming Loki queries. * `query-frontend-headless` to be used for discovering QF pod IPs from queriers to connect as workers. **Checklist** - [x] `CHANGELOG.md` updated - [x] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md`	3 years ago

Susana Ferreira	f93b91bfb5	Add configuration documentation generation tool (#7916) ... **What this PR does / why we need it**: Add a tool to generate configuration flags documentation based on the flags properties defined on registration on the code. This tool is based on the [Mimir doc generation tool](https://github.com/grafana/mimir/tree/main/tools/doc-generator) and adapted according to Loki configuration specifications. Prior to this PR, the configuration flags documentation was dispersed across two sources: * [_index.md](5550cd65ec/docs/sources/configuration/_index.md) * configuration flags registration in the code This meant that there was no single source of truth. In this PR, the previous `_index.md` file is replaced with the new file generated by the tool. The next step includes adding a CI step that validates if the _index.md file was generated according to the flags settings. This will be done in a follow-up PR. **NOTE:** this is not a documentation update PR. Apart from some minor typo fixes, the documentation changes on the code, were copied from the `_index.md` file. **Which issue(s) this PR fixes**: Fixes https://github.com/grafana/loki-private/issues/83 **Special notes for your reviewer**: Files: * [docs/sources/configuration/index.template](5550cd65ec/docs/sources/configuration/index.template): template used to generate the final configuration file * [/docs/sources/configuration/_index.md](c32e5d0acb/docs/sources/configuration/_index.md): file generated by tool * `loki/pkg` directory files updated with up-to-date documentation from `_index.md` file * [tools/doc-generator](5550cd65ec/tools/doc-generator) directory with documentation generation tool. **Checklist** - [ ] Reviewed the `CONTRIBUTING.md` guide - [ ] Documentation added - [ ] Tests updated - [ ] `CHANGELOG.md` updated - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md`	3 years ago
