Irina	4cd1246b88	Logproto: Extract push.proto from logproto package to the separate module (#8259 ) Co-authored-by: Owen Diehl <ow.diehl@gmail.com>	2 years ago
Owen Diehl	07487cd89d	fixes bug with queryIngesterWithin logic in asyncStore ingester stats… (#8145 ) Fixes a previous mistake in the logic calculating when to skip querying ingesters in the async store Statistics method. Notably `through.After` should be `through.Before` when skipping querying ingesters as that's when there's no overlap with the `query-ingesters-within` period: ```go // OLD CODE BELOW if a.queryIngestersWithin != 0 { // don't query ingesters if the query does not overlap with queryIngestersWithin. if !through.After(model.Now().Add(-a.queryIngestersWithin)) { // <----- should be through.Before return a.Store.Stats(ctx, userID, from, through, matchers...) } } ``` I discovered the problem while debugging querier OOMs during a boltdb-shipper -> tsdb migration and ultimately found this happened under the following circumstances: * Queries over high volumes of _recent_ data wouldn't query ingesters for index metadata * Without index metadata, we only checked storage metadata * There is a delay before we ship the index to storage, meaning we don't see it if ingesters are skipped * Calculating ideal shard factors without recent data for queries that only touch recent data _dramatically_ underestimates the desired shard factor * Queries aren't split enough and get scheduled onto too few querier replicas * They oom. We had some fun examples like a single replica trying to download 419,000 chunks/query To be clear, this is still a hypothesis, but a plausible one, especially after finding the boolean logic error this PR fixes. Instead of changing this one line, I took the opportunity to refactor this into a shared utility used by our other `GetChunkRefs` method which is already tested, ensuring the logic works as expected. I also added some more logging visibility into this code so we can understand what the difference is when querying statistics from storage vs ingesters. Finally, I added a helper to prepare our `Stats` objects to be logged which is now used in a few places.	2 years ago
Robert Fratto	85392a9728	Update Prometheus dependency to latest release (v2.40.4) (#7826 ) Closes #7811, which is needed for Grafana Agent to update to v2.40 and add support for native histograms. I did not add support for native histograms to Loki, sorry :)	3 years ago
Travis Patterson	c75b822fc6	Track rates per stream and per tenant (#7564 ) It is possible for two tenants to have streams with the same labels. This PR changes the stream tracking in the `shard_tracker`, `stream_rate_calculator`, and `rate_store` to account for tenant ID when tracking streams.	3 years ago
Dylan Guedes	da5378c927	Loki: Remove RatelimitedStream proto (#7235 ) What this PR does / why we need it: Remove an unused proto (RateLimitedStream). It was only used for an older approach to deal with rate-limited streams but since we changed approaches this isn't necessary anymore.	3 years ago
Travis Patterson	e3e4e27c8c	Implement ingester API to return stream rates (#7176 ) This PR introduces an API on the Ingester that reports all current streams in memory and their current rate in bytes/second. The reponse from the API contains a slice of `StreamRate` structs: ```go type StreamRate struct { StreamHash uint64 `protobuf:"varint,1,opt,name=streamHash,proto3" json:"streamHash,omitempty"` StreamHashNoShard uint64 `protobuf:"varint,2,opt,name=streamHashNoShard,proto3" json:"streamHashNoShard,omitempty"` Rate int64 `protobuf:"varint,3,opt,name=rate,proto3" json:"rate,omitempty"` } ``` In the interest of space on the caller and in transmission, only hashes and rates are sent. - `StreamHash` will be used to deduplicate replicas - `StreamHashNoShard` will be used to aggregate a sharded stream's total rate.

Dylan Guedes	bba6c14459	Loki: Modify ingesters to return rate-limited streams to distributors (#6977 ) What this PR does / why we need it: Modify ingesters to return a list of rate-limited streams on its reply to `(distributor).Push`. This is done by using the gRPC details feature. I've updated the tests and apparently, the returned error message is exactly the same so this shouldn't be a breaking change. Also modifies `(stream).Push` to return a list of all entries with errors instead of returning the final gRPC error. This will allow us in the future to easily return to distributors the indices of all reject entries, so that distributors won't have to always retry all entries. This work is necessary for the new stream sharding feature.	3 years ago

Robert Fratto	d34b1f7450	ingester: support chunk transfers on ingester shutdown. This commit introduces chunk transfers, borrowing the mechanism from Cortex's implementation: when an ingester is shut down with claim on rollout enabled, the ingester will find a pending ingester and transfer all of its chunks to it.	6 years ago
sh0rez	38cb093358	feat(loki): extended tailing (#764 ) * refactor(querier/ingester): TailRequest Lookback window Moves the specifications of the Lookback Window out of the logproto.QueryRequest into it's own type logproto.Lookback. This is required, because the Lookback Window will be used in the TailRequest as well. * feat(querier): parse Lookback from HTTP Request * feat(logcli): send Lookback Window spec with tail request * feat(querier): include historic entries in tail mode Extends tailing by sending a configurable amount of historic entries with before the live entries. This enables a behaviour that is closer to kubectl logs -f and docker logs -f. It is implemented by running a regular Query before subscribing to the ingesters. * fix: adapt tests to Lookback change * feat(querier): check all errors to make the linter happy * fix(logproto): flatten Lookback window spec Flattens the Lookback window spec into the individual queries * fix(ingester): adapt test to Lookback flatten	6 years ago
