Dylan Guedes	4f94b89fdb	Loki: Add more spans to write path (#8888 ) What this PR does / why we need it: Add new spans to our write path to better determine which operations are holding our write performance.	2 years ago
Callum Styan	9a2a038f43	Allow passing of context to query related limits functions (#8689 ) In this PR we're allowing for passing of a `context.Context` via the Limits interfaces (some of which are new, to clean up hardcoding/embedding of `validation.Overrides`) This is based on work/ideas by @jeschkies . Fixes #8694 --------- Signed-off-by: Callum Styan <callumstyan@gmail.com> Co-authored-by: Karsten Jeschkies <karsten.jeschkies@grafana.com>	2 years ago
Kaviraj Kanagaraj	db3a9c961e	distributor: Fix `loki_mutated_bytes_total` metric increment (#8223 ) Signed-off-by: Kaviraj <kavirajkanagaraj@gmail.com> Previously this metric was not not incremented for all the log lines in the stream. This PR fixes it.	2 years ago
Travis Patterson	a1e9e4cdd0	Revert "Make some stream shard metrics per-tenant (#7838 )" (#7842 ) Because these metrics will be coming from each distributor, this is going to have an adverse impact on cardinality. Consider doing this with logging	3 years ago
Travis Patterson	96fc2abfff	Make some stream shard metrics per-tenant (#7838 ) This PR just adds tenant information so some of our per-stream-rate-limit metrics.	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
Travis Patterson	a65da7d78e	Shard streams round-robin rather in batches. (#7560 ) To avoid hot spots, keep track of shard numbers across pushes. When tracking shard numbers across pushes, it's no longer necessary to randomize shards, in the case where the desired number of shards is greater than the number of entries. Instead, we just partition the entries among the shards in round robin fashion. Over time, this should give us a more even distribution of logs in shards, particularly for large streams that are made of small individual pushes.	3 years ago
Travis Patterson	0a654e2357	Ensure labels on sharded streams are sorted before they're sent anywhere (#7556 ) Pushing streams with unsorted labels to ingesters results in a bug where ingesters duplicate chunks for streams. This causes a memory leak and eventual OOM crash when ingesters recover from the WAL because one of the duplicate streams is orphaned. This PR ensures that sharded streams have sorted labels to avoid this bug.	3 years ago
Callum Styan	46b40a5582	Hardcode ring.WriteNoExtend for distributor push operations (#7517 ) With zone awareness enabled we allow restarting multiple ingesters within a single zone at the same time, this means that for many more write requests there's potentially only 2 of the 3 replicas for a stream up at the time the write request is received. This lead to a large increase in 500s during rollouts. My suspicion is that the 500s on rollouts was always related to the following; the replica set ring code has something referred to as "extending the replica set". This essentially is the adding of ingesters in the ring that are not in an ACTIVE state (for example, are in LEAVING) to the set of replicas considered valid for an operation. Adding of the instance in a state other than ACTIVE can be controlled by using a different operation type, which Mimir was using but we were not. Here are the relevant functions, [ring.Get](`8d6d914ef6/ring/ring.go (L335-L403)`) (particularly these lines [1](`8d6d914ef6/ring/ring.go (L381-L389)`) and [2](`8d6d914ef6/ring/ring.go (L394-L397)`)) and [replicationStrategy.Filter](`789ec0ca4a/ring/replication_strategy.go (L22-L71)`) (particularly these lines [1](`789ec0ca4a/ring/replication_strategy.go (L32-L36)`) and [2](`789ec0ca4a/ring/replication_strategy.go (L54-L67)`)) The tl; dr of the above code snippets is that we seem to always have required a minSuccess from replicationFactor/2 + 1 except we overwrite replicationFactor to be the # of instances which is likely always going to be more than just 3 ingester replicas because of the replica set extension. At least for zone aware rollouts this seems to be the case. This is because many ingesters will be in the LEAVING state. We can avoid this by just using `WriteNoExtend` operations instead of `Write` operations ([here](`789ec0ca4a/ring/ring.go (L83-L93)`)) In this PR I've hardcoded our call to the ring in `distributor.Push` to always use `ring.WriteNoExtend`. IMO this is the better option to allowing `ring.WriteNoExtend` to be used optionally and defaulting to `ring.Write`. Extending the replication set on writes feels like a footgun for write outages and there's even some feelings internally that allowing that extension is a bug.

Dylan Guedes	28e192f22e	Loki: Implement random entries assignment when sharding (#7427 ) What this PR does / why we need it: Modify sharding to assign random shards when the number of shards is bigger than the number of entries. This helps us to avoid hot-spotting the first shards. By randomizing the entries assignment we help spread the load between all shards.	3 years ago
Travis Patterson	8c84ee8b7a	Fix stream sharding (#7393 ) Promtail doesn't add a stream hash to push requests. As a result, we weren't accounting for the current rate in our sharding calculation and only sharding on individual large pushes. This PR ensures that streams have a hash as they're ingested. It also add a couple of metrics that were useful in debugging this issue.	3 years ago
Travis Patterson	7979cfbe07	Implement Distributor Rate Store (#7349 ) The `RateStore` concurrently queries all ingester `GetStreamRate` APIs and stores the results. `RateStore` deduplicates replicas and combines sharded streams so a caller of `RateFor` gets an unsharded view of a stream's rate.	3 years ago
Dylan Guedes	b1d4efab12	Loki: Per-tenant stream sharding (#7311 ) What this PR does / why we need it: - Move stream sharding configuration to its own package to avoid cyclic imports - Change stream sharding to be a per-tenant configuration - Change ingesters to reject whole streams due to rate-limit based on per-tenant stream sharding - Change stream sharding flags prefix from `distributor.shard-stream` to `shard-stream`	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	da7acb49e5	Loki: Add sharding support for negative/zeroed desired rate (#7342 ) What this PR does / why we need it: Adds the handling of negative/zeroed desired rate to our distributor stream sharding. Without this, invalid desired rates results in a -Inf number of shards. This also adds a log line to report that such a thing happened.

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
Dylan Guedes	dcfba366de	Loki: Shard streams based on desired rate (#7199 ) What this PR does / why we need it: Modify our sharding mechanism to be dictated by the desired rate and ingestion rate. Once the number of shards is calculated, the stream entries will be distributed across the shards. If the number of entries is lower than number of shards, we report a metric and use number of entries as the number of shards.	3 years ago
Christian Haudum	67b12f2357	Update distributor push tests (#6641 ) Adds a test case for concurrent pushes (which would have spotted a bug in https://github.com/grafana/loki/pull/5248) and a test case for tolerance regarding replication factor. The PR also replaces the mock ring with an actual in-memory kv store ring. And variables and function names were changed to meet Loki/logs terminology.

Dylan Guedes	2bb2a2c0e1	Loki: Remove ring client from the distributor (#6622 ) Removes the ring client from the distributor. - It was originally added on PR #4938 because it was the only ring implementation with HTTPHandler support (used for the ring page).

Old message ``` {"code":400,"status":"error","message":"entry for stream '{foo=\"bar\"}' has timestamp too old: 1970-01-01 01:00:00.5 +0100 CET"} ``` New message ``` {"code":400,"status":"error","message":"entry for stream '{foo=\"bar\"}' has timestamp too old: 2021-12-28 01:48:45.5 +0100 CET, accepts timestamp from: 2021-12-29 09:48:45.737756651 +0100 CET"} ``` main rationale being, hard to know what is the closest timestamp that Loki is expecting without going through the config.

Dylan Guedes	98ecfefd89	Add distributor ring page (#4938 ) * Implement new IngestionRateStrat Enum. - This new IngestionRateStrat is used internally to represent the chosen ingestion rate strategy, to avoid using plain strings. * Add a ring to the distributor. As of now, the distributor only has a pointer to its lifecycler.

Dylan Guedes	0d66319a1f	Revert distributor defaulting to inmemory. (#4638 ) - [PR 4440](https://github.com/grafana/loki/pull/4440/files) modified the distributor setup to use inmemory by default (instead of consul). That was necessary because, by changing the default rate limiting to global, a ring was necessary, and since by default the ring was set to consul, the project couldn't run with the default configs. That's not the case anymore: right now we are reusing the same config set for the ingester (which users already have properly configured otherwise they wouldn't be able to run the project).
