It also releases file descriptors for removed files (journal vacuuming). The `defaultJournalEntryFunc` is only called once upon startup. It creates a `Journal` instance to only read a single entry to determine the age of the entry referenced in the positions file. Right after, this instance is not required anymore.

The issue is the following: - There are two goroutines that tailer manages: one for reading lines, the other for updating positions: https://github.com/grafana/loki/blob/main/clients/pkg/promtail/targets/file/tailer.go#L103 - The tailer can be cleanly stopped & drained via `.Stop()` https://github.com/grafana/loki/blob/main/clients/pkg/promtail/targets/file/tailer.go#L221 - But if the goroutine reading lines encounters an error from the underlying `tail`, the tailer is stopped without draining using the defer statement here: https://github.com/grafana/loki/blob/main/clients/pkg/promtail/targets/file/tailer.go#L151 - The above defer statement does not shut down the position updating goroutine and the `.Stop()` won't be called, so we end up with a leaked goroutine. **Which issue(s) this PR fixes**: Fixes https://github.com/grafana/agent/issues/3885 As can be seen in the [goroutine dump attached to the issue](https://gist.github.com/amseager/e37f31984facd9cbc51ce0f2153d6864), there were 933 update position goroutines, while we only had 21 files being tailed. **Special notes for your reviewer**: **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [x] Tests updated - [x] `CHANGELOG.md` updated	2 years ago
Pablo	306c96ce8a	Notification based Promtail WAL Watcher polling approach (#9135) ... **What this PR does / why we need it**: This PR implements a new mechanism for the wal Watcher in Promtail, to know there are new records to be read. It uses a combination of: - https://github.com/prometheus/prometheus/pull/11950 - https://github.com/prometheus/prometheus/pull/11949 The main idea is that the primary mechanism is a notification channel between the `wal.Writer` and `wal.Watcher`. The Watcher subscribes to write events the writer publishes, getting notified if the wal has been written. The same subscriptions design is used for cleanup events. As a backup, the watcher has a timer that implements an exponential backoff strategy, which is constrained by a minimum and maximum that the user can configure. Below the cpu difference is shown of running both main and this branch against the same scrape target. <img width="2496" alt="image" src="https://user-images.githubusercontent.com/2617411/232099483-7e5c36fa-9360-4eb9-8240-687adf46e330.png"> The yellow line is the latest main build from where this branch started, and the green line is this branch. Both promtails tailing docker logs, and using the following metrics to get cpu usage from cadvisor: ``` avg by (name) (rate(container_cpu_usage_seconds_total{job=~".+", instance=~".+", name=~"promtail-wal-test_promtail.+"}[$__rate_interval])) ``` **Which issue(s) this PR fixes**: Part of https://github.com/grafana/loki/issues/8197 **Special notes for your reviewer**: **Checklist** - [ ] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] Documentation added - [ ] Tests updated - [ ] `CHANGELOG.md` updated - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md`	2 years ago

Robert Fratto	7bec727c6d	promtail: support configurable polling interval (#8874) ... Currently, Promtail always polls files every 250ms. This PR allows the polling period to be customized, starting at a minimum polling period and exponentially increasing the polling frequency to a bounded maximum if the file has no changes. When file changes are detected, the polling frequency resets to the minimum. The default behavior is the existing behavior; both the minimum and maximum polling intervals are set to 250ms. I'm opening this in draft to get early feedback. There's a few open questions: * Where can I add validations to ensure that the min/max polling intervals are configured properly? * Is this the right approach for implementation? Do I need to make any changes? * Does this need tests? I'll update the CHANGELOG and Documentation after we're agreed on an approach.	2 years ago

Dylan Guedes	6dfcd59c1b	Promtail: Add `decompression` configuration (#8994) ... **What this PR does / why we need it**: Adds a new `compression` configuration to Promtail to customize decompression behavior. As of now, two options are supported: `enabled`: false by default but if truthy, Promtail will infer a compression algorithm to use based on the file extension `initialDelay`: 0 by default but if higher, Decompressor will sleep for the given duration before trying to decompress. This is to avoid scenarios where the Decompressor starts to work on a file that is still being compressed/generated. **Which issue(s) this PR fixes**: Fixes https://github.com/grafana/loki/issues/8784	2 years ago
René Scheibe	46af2cdcf1	Promtail: Prevent logging errors on normal shutdown (#8988) ... **What this PR does / why we need it**: Since PR #4066 two messages are logged for the errors `ErrExpired` and `EOF`, whereas nothing has been logged beforehand. As `ErrExpired` is returned by the `JournalReader` after sending a message to the `until` channel to signal a normal stop, this should not be logged as an error.	2 years ago
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. **Checklist** - [ ] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] Documentation added - [ ] Tests updated - [ ] `CHANGELOG.md` updated - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md`	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. **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: Pablo <2617411+thepalbi@users.noreply.github.com> Co-authored-by: Paschalis Tsilias <tpaschalis@users.noreply.github.com> Co-authored-by: J Stickler <julie.stickler@grafana.com>	2 years ago
