Christian Haudum	abc0fd26d2	Enforce per tenant queue size (#8947 ) What this PR does / why we need it: Prior to the changes in https://github.com/grafana/loki/pull/8752 the max queue size per tenant was enforced by the size of the buffered channel to which a request was enqueued. However, since we have hierarchical queues, every sub-queue has the same channel capacity as the root (tenant) queue. Therefore the total queue size per tenant needs to be tracked separately, so requests can be rejected when the max queue size is reached.

Christian Haudum	0adedfa689	Revert high cardinality metric in scheduler (#8946 ) What this PR does / why we need it: The metrics was useful for initial testing of the new scheduler queue implementation but yields high cardinality metrics, which is not desired. Also, the metric does not add additional value beyond the initial testing phase.

Pablo	89996c9714	Promtail WAL support: Implement reader side (#8302 ) What this PR does / why we need it: This PR is the second in a series that will implement WAL support into Promtail. The main objective of this PR is implement the reader side of WAL. That is, using the previously instantiated `client.Manager` to somehow read entries from the WAL instead of receiving them from a channel. Pending work: - [x] Implement mechanism so that `WriteTo` targets of each `wal.Watcher` can cleanup un-used series - [x] Write a full fledged test-case that tests a WAL enabled Promtail (maybe in a follow up) Which issue(s) this PR fixes: Part of #8197 Special notes for your reviewer: The line count might be big since this PR implements two fully fledged test cases of Promtail with WAL enabled.

Salva Corts	d421feafe6	Log when returning query-time limit (#8938 ) What this PR does / why we need it: At https://github.com/grafana/loki/pull/8727 we introduced various limits that can now be configured at query time. We always compare the value of the limit configured at query time with the value set on the overrides for the tenant or the default if not configured (aka original); applying the most restrictive one. If the most restrictive is the original value or the limit is not configured at query-time, we print the following debug message: `9e1846c47a/pkg/util/querylimits/limiter.go (L43)` It will be printed many times: every time the query is not configured at query-time, as well as every time the original value is more restrictive. Moreover, this log message lacks some useful information such as the original value, the query-time value, the tenant ID and the limit name. This PR fixes this by removing the debug message above and printing a new debug message only if we return the query-time limit. This new log also prints the tenant ID, the limit name, as well as the original and the query-time limit values.

Salva Corts	45775c82f7	Implement `RequiredNumberLabels` query limit (#8918 ) What this PR does / why we need it: As pointed out in https://github.com/grafana/loki/pull/8851, some queries can impose a great workload on a cluster by selecting too many streams. Similarly to the `RequiredLabels` limit introduced at https://github.com/grafana/loki/pull/8851, here we add a new limit `RequiredNumberLabels` to require queries to specify at least N label. For example, if the limit is set to 2, then the query should contain at least 2 label matchers. This limit can be configured per tenant and at query time. ![image](https://user-images.githubusercontent.com/8354290/228271398-4b9bcc49-f539-4e94-86c1-071e519a30a9.png) Which issue(s) this PR fixes: Fixes https://github.com/grafana/loki-private/issues/699 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 - [x] `CHANGELOG.md` updated - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md` --------- Co-authored-by: Dylan Guedes <djmgguedes@gmail.com>	2 years ago

Salva Corts	ee69f2bd37	Split index request in 24h intervals (#8909 ) What this PR does / why we need it: At https://github.com/grafana/loki/pull/8670, we applied a time split of 24h intervals to all index stats requests to enforce the `max_query_bytes_read` and `max_querier_bytes_read` limits. When the limit is surpassed, the following message get's displayed: ![image](https://user-images.githubusercontent.com/8354290/227960400-b74a0397-13ef-4143-a1fc-48d885af55c0.png) As can be seen, the reported bytes read by the query are not the same as those reported by Grafana in the lower right corner of the query editor. This is because: 1. The index stats request for enforcing the limit is split in subqueries of 24h. The other index stats rquest is not time split. 2. When enforcing the limit, we are not displaying the bytes in powers of 2, but powers of 10 ([see here][2]). I.e. 1KB is 1000B vs 1KiB is 1024B. This PR adds the same logic to all index stats requests so we also time split by 24 intervals all requests that hit the Index Stats API endpoint. We also use powers of 2 instead of 10 on the message when enforcing `max_query_bytes_read` and `max_querier_bytes_read`. ![image](https://user-images.githubusercontent.com/8354290/227959491-f57cf7d2-de50-4ee6-8737-faeafb528f99.png) Note that the library we use under the hoot to print the bytes rounds up and down to the nearest integer ([see][3]); that's why we see 16GiB compared to the 15.5GB in the Grafana query editor. Which issue(s) this PR fixes: Fixes https://github.com/grafana/loki/issues/8910 Special notes for your reviewer: - I refactored the`newQuerySizeLimiter` function and the rest of the _Tripperwares_ in `rountrip.go` to reuse the new IndexStatsTripperware. So we configure the split-by-time middleware only once.

Travis Patterson	163fd9d8af	Short circuit parsing when label matchers are present (#8890 ) This PR makes parsers aware of any downstream label-matcher stages at parse time. As labels are parsed, if one has a matcher, the matcher is checked at parse time. If the label does not match it's matcher, parsing is halted on that log line. ex 1: consider the log: `foo=1 bar=2 baz=3` And the query `{} \| logfmt \| bar=3` When `bar` is parsed it is immediately checked against it's matcher. The match fails so we the parser never spends time parsing the rest of the line. ex 2: consider the log: `foo=1 baz=3 bletch=4` And the query `{} \| logfmt \| bar=3` `bar` is never seen in the log so the whole line is parsed.

Salva Corts	336e08fc4b	Salvacorts/max querier size messaging (#8916 ) What this PR does / why we need it: In https://github.com/grafana/loki/pull/8670 we introduced a new limit `max_querier_bytes_read`. When the limit was surpassed the following error message is printed: ``` query too large to execute on a single querier, either because parallelization is not enabled, the query is unshardable, or a shard query is too big to execute: (query: %s, limit: %s). Consider adding more specific stream selectors or reduce the time range of the query ``` As pointed out in [this comment][1], a user would have a hard time figuring out whether the cause was `parallelization is not enabled`, `the query is unshardable` or `a shard query is too big to execute`. This PR improves the error messaging for the `max_querier_bytes_read` limit to raise a different error for each of the causes above.

André Águas	44f1d8d7f6	azure: respect retry config before cancelling the context (#8732 ) What this PR does / why we need it: On GET blob operations a context timeout is set to `RequestTimeout`, however this value is not the full timeout. This is only the first timeout and afterwards there are retries. As a result, the retry configuration is never used because the context is immediately cancelled. To fix we should set the context timeout to a value larger than the Azure timeout after retries. Since the backoff is exponential and randomized we need to take the value of `MaxRetryDelay` to set an upper bound.	2 years ago

Danny Kopping	c9d5a91206	Ruler: Implement consistent rule evaluation jitter (#8896 ) What this PR does / why we need it: This PR replaces the previous random jitter with a consistent jitter. While both are random, having the random jitter be applied _consistently_ is essential for evaluating rules on a predictable cadence. If a rule is supposed to evaluate every minute, whether it evaluates at (e.g.) `01:00` or `01:03.234` is irrelevant because the evaluation _instant_ is not adjusted, so it will produce the same result whether run at `01:00` or `01:03.234`. However, if 1000 rules are set to evaluate at `01:00`, this will create a resource contention issue.	2 years ago

Andrii Kushch	17e05d28e4	Promtail: Add a new target for the Azure Event Hub (#8787 ) What this PR does / why we need it: We want to allow receiving logs from the Azure Cloud. To solve this problem, we need to be able to configure Promtail to consume logs from the Azure Events Hub. To achieve this goal, we need to add a new configuration option to the scrape configuration in Promtail and implement the component that, given this configuration, can connect to the Azure Event Hub, parse received data, and prepare it to be stored in Loki. Which issue(s) this PR fixes: Fix [#8788](https://github.com/grafana/loki/issues/8788) # Special notes for your reviewer: With the current implementation, I would like to leverage Azure Events Hub's compatibility with a Kafka protocol and reuse code for a Kafka target. ### Why I decided to create a new target instead of just reusing the Kafka target: 1. Configuration for Kafka in this scenario requires fewer parameters. For example, version and auth should have some specific values. 2. Message handling is different for Azure Logs. In addition to what we are doing for the Kafka target, we want to fix JSON and split incoming messages into multiple log lines before propagating it further. ### From the implementation perspective, there are two goals: - Extract interfaces that are not Kafka configuration specific from the Kafka target module. Splitting Kafka config parsing and target creation. - To make the message handler/parser injectable or configurable: we would like to fix JSON and split a message into multiple messages.

Bryan Boreham	793a689d1f	Iterators: re-implement mergeEntryIterator using loser.Tree for performance (#8637 ) What this PR does / why we need it: Building on #8351, this re-implements `mergeEntryIterator` using `loser.Tree`; the benchmark says it goes much faster but uses a bit more memory (while building the tree). ``` name old time/op new time/op delta SortIterator/merge_sort-4 10.7ms ± 4% 2.9ms ± 2% -72.74% (p=0.008 n=5+5) name old alloc/op new alloc/op delta SortIterator/merge_sort-4 11.2kB ± 0% 21.7kB ± 0% +93.45% (p=0.008 n=5+5) name old allocs/op new allocs/op delta SortIterator/merge_sort-4 6.00 ± 0% 7.00 ± 0% +16.67% (p=0.008 n=5+5) ``` The implementation is very different: rather than relying on iterators supporting `Peek()`, `mergeEntryIterator` now pulls items into its buffer until it finds one with a different timestamp or stream, and always works off what is in the buffer. The comment `"[we] pop the ones whose common value occurs most often."` did not appear to match the previous implementation, and no attempt was made to match this comment. A `Push()` function was added to `loser.Tree` to support live-streaming. This works by finding or making an empty slot, then re-running the initialize function to find the new winner. A consequence is that the previous "winner" value is lost after calling `Push()`, and users must call `Next()` to see the next item. A couple of tests had to be amended to avoid assuming particular behaviour of the implementation; I recommend that reviewers consider these closely.

Bill Franklin	3ed9f0c9ef	Canary: support filtering / parsing logs with LogQL (#8871 ) What this PR does / why we need it: The canary logs can be shipped to Loki in various formats. This allows users of the canary to parse out the canaries logs from any format e.g. nested json. The alternative is to do something different for the canary logs to prevent the logs being wrapped / manipulated (e.g. write to Loki directly, or use a different log pipeline) which limits the benefits of the canary. I've confirmed this works locally.

Salva Corts	d24fe3e68b	Max bytes read limit (#8670 ) What this PR does / why we need it: This PR implements two new per-tenant limits that are enforced on log and metric queries (both range and instant) when TSDB is used: - `max_query_bytes_read`: Refuse queries that would read more than the configured bytes here. Overall limit regardless of splitting/sharding. The goal is to refuse queries that would take too long. The default value of 0 disables this limit. - `max_querier_bytes_read`: Refuse queries in which any of their subqueries after splitting and sharding would read more than the configured bytes here. The goal is to avoid a querier from running a query that would load too much data in memory and can potentially get OOMed. The default value of 0 disables this limit. These new limits can be configured per tenant and per query (see https://github.com/grafana/loki/pull/8727). The bytes a query would read are estimated through TSDB's index stats. Even though they are not exact, they are good enough to have a rough estimation of whether a query is too big to run or not. For more details on this refer to this discussion in the PR: https://github.com/grafana/loki/pull/8670#discussion_r1124858508. Both limits are implemented in the frontend. Even though we considered implementing `max_querier_bytes_read` in the querier, this way, the limits for pre and post splitting/sharding queries are enforced close to each other on the same component. Moreover, this way we can reduce the number of index stats requests issued to the index gateways by reusing the stats gathered while sharding the query. With regard to how index stats requests are issued: - We parallelize index stats requests by splitting them into queries that span up to 24h since our indices are sharded by 24h periods. On top of that, this prevents a single index gateway from processing a single huge request like `{app=~".+"} for 30d`. - If sharding is enabled and the query is shardable, for `max_querier_bytes_read`, we re-use the stats requests issued by the sharding ware. Specifically, we look at the [bytesPerShard][1] to enforce this limit. Note that once we merge this PR and enable these limits, the load of index stats requests will increase substantially and we may discover bottlenecks in our index gateways and TSDB. After speaking with @owen-d, we think it should be fine as, if needed, we can scale up our index gateways and support caching index stats requests. Here's a demo of this working: <img width="1647" alt="image" src="https://user-images.githubusercontent.com/8354290/226918478-d4b6c2fd-de4d-478a-9c8b-e38fe148fa95.png"> <img width="1647" alt="image" src="https://user-images.githubusercontent.com/8354290/226918798-a71b1db8-ea68-4d00-933b-e5eb1524d240.png"> Which issue(s) this PR fixes: This PR addresses https://github.com/grafana/loki-private/issues/674. Special notes for your reviewer: - @jeschkies has reviewed the changes related to query-time limits. - I've done some refactoring in this PR: - Extracted logic to get stats for a set of matches into a new function [getStatsForMatchers][2]. - Extracted the _Handler_ interface implementation for [queryrangebase.roundTripper][3] into a new type [queryrangebase.roundTripperHandler][4].

Karsten Jeschkies	94725e7908	Define `RequiredLabels` query limit.

Sandeep Sukhani	4e893a0a88	tsdb: sample chunk info from tsdb index to limit the amount of chunkrefs we read from index (#8742 ) What this PR does / why we need it: Previously we used to read the info of all the chunks from the index and then filter it out in a layer above within the tsdb code. This wastes a lot of resources when there are too many chunks in the index, but we just need a few of them based on the query range. Before jumping into how and why I went with chunk sampling, here are some points to consider: * Chunks in the index are sorted by the start time of the chunk. Since this does not tell us much about the end time of the chunks, we can only skip chunks that start after the end time of the query, which still would make us process lots of chunks when the query touches chunks that are near the end of the table boundary. * Data is written to tsdb with variable length encoding. This means we can't skip/jump chunks since each chunk info might vary in the number of bytes we write. Here is how I have implemented the sampling approach: * Chunks are sampled considering their end times from the index and stored in memory. * Here is how `chunkSample` is defined: ``` type chunkSample struct { largestMaxt int64 // holds largest chunk end time we have seen so far. In other words all the earlier chunks have maxt <= largestMaxt idx int // index of the chunk in the list which helps with determining position of sampled chunk offset int // offset is relative to beginning chunk info block i.e after series labels info and chunk count etc prevChunkMaxt int64 // chunk times are stored as deltas. This is used for calculating mint of sampled chunk } ``` * When a query comes in, we will find `chunkSample`, which has the largest "largestMaxt" that is less than the given query start time. In other words, find a chunk sample which skips all/most of the chunks that end before the query start time. * Once we have found a chunk sample which skips all/most of the chunks that end before the query start, we will sequentially go through chunks and consider only the once that overlap with the query range. We will stop processing chunks as soon as we see a chunk that starts after the end time of the query since the chunks are sorted by start time. * Sampling of chunks is done lazily for only the series that are queried, so we do not waste any resources on sampling series that are not queried. * To avoid sampling too many chunks, I am sampling chunks at `1h` steps i.e given a sampled chunk with chunk end time `t`, the next chunk would be sampled with end time >= `t + 1h`. This means typically, we should have ~28 chunks sampled for each series queried from each index file, considering 2h default chunk length and chunks overlapping multiple tables.

Joao Marcal	1549fec2fa	mixins: Normalize headless service name for query-frontend/scheduler (#8880 ) What this PR does / why we need it: Mixins in general are rather complex pieces of code to consume. When trying to use the loki mixins it wasn't apparent at first that I could use a headless service for DNS SRV discovery for both query_frontend and query_scheduler, especially because for frontend the service is named `query_frontend_headless_service` and for the scheduler, it's named `query_scheduler_service_discovery`. Furthermore, the query_frontend mixin provides a non-headless version of the service while query_scheduler doesn't. This PR aims at normalizing this for end users, both headless services are now named `query_frontend_headless_service` and `query_scheduler_headless_service` and both also provide a non-headless version of the service.	2 years ago
