Everyone attending the event, please join us!
Date: December 5th 14:00-14:40
Speakers: Daijiro Fukuda and Kentaro Hayashi from ClearCode Inc.
Summary:
Fluentd, the CNCF graduated project, starts a new chapter as the OSS project. Fluentd community released the new package fluent-package as the successor of td-agent and started providing a new release cycle to fit better with needs. This talk is going to share the latest news of Fluentd, including its updates, package, rebranding and so on, with people who are using Fluentd or struggling to manage their logs. Fluentd is an open source data collector that unifies data collection and consumption. Because of its flexible plugin system and scalability, Fluentd is adopted in various systems and has become a de facto standard, especially for scale logging in distributed systems.
In the new release cycle, the package applies only bug fixes and security fixes of Fluentd over a long term, about two years. We are confident that this will meet the demands of users who want to use Fluentd stably over the long term. In this session, we will talk about (a) the history of Fluentd v1 and td-agent v4, (b) why Fluentd community decided to rebrand existing td-agent to fluent-package, (c) what the benefits and impacts of the new release cycle are, and (d) how to upgrade to fluent-package from td-agent.

Hi users!
We have released fluent-package v5.0.2 and td-agent v4.5.2. fluent-package is a stable distribution package of Fluentd.
This is a maintenance release of v5.0.x LTS series.
As significant in_tail
bugs (wrongly stopping tailing logs) were fixed in latest release, we recommend upgrading to fluent-package v5.0.2!
in_tail

See Fluentd v1.16.3 and v1.16.2 have been released blog article about details.We plan to ship next LTS version of fluent-package v5.0.3 on Feb, 2024. The content of updates are still in T.B.D.
This is a exceptional maintenance release of v4.5.x series.
Fluentd was updated to 1.16.3 because it contains significant bug fixes about in_tail
.
Note that td-agent will not be updated anymore.

Hi users!
We have released v1.16.3 (changelog) on 2023-11-14. We also describe the content of v1.16.2 (changelog) on 2023-07-14 here.
In these releases, in_tail
issues that have been reported for years are fixed!
And other some bug fixes too.
in_tail
: Fix in_tail
wrongly stopping tailing the current target file and causing handle leaksThis issue has been reported for years. It was looking very serious, but the cause remained unclear until recently.
At last, we found different causes when the follow_inodes option is true
and when it is false
(default).
We fixed the problem of follow_inodes true
case in v1.16.2, and fixed the problem of follow_inodes false
case in v1.16.3.
Especially, in follow_inodes false
case, the trouble was mainly caused by rotate_wait option.
In past versions, please avoid using large value for this option.
In particular, if you make it greater than refresh_interval option, it will surely cause this issue.
In Fluentd v1.15.1 (td-agent v4.4.0) or later, the following warning log is recorded when this issue occurs.
Skip update_watcher because watcher has been already updated by other inotify event
If this issue occurs, please restart Fluentd, and please update Fluentd to the latest version. fluent-package v5.0.2 will be released in this month and it contains these fixes.
See the following PRs for more information.

: Fix corrupted data possibly breaking other data. #4178NoMethodError

Hi users and developers!
We announce the dropping schedule for TD Agent 4 development.
Since td-agent 4.0.0 was released in 2020, td-agent 4 has been maintained for a long time.
As new major version of td-agent 4 was rebranded (to fluent-package
v5), and released in August 2023,
we decided to stop maintaining td-agent 4.
As you know, already stepping down maintenance activity, new minor update for td-agent 4 will not be shipped anymore. (td-agent v4.5.1 will be the last release of this series, it will be shipped in this month.)
Thus, we recommend using fluent-package v5 for new deployment :)
There is a good article to do it.
Follow the above instructions.
Hi users!
We have released fluent-package
v5.0.0 (Release Candidate) and
the following v5.0.1 (General Availability).
fluent-package is formerly known as td-agent
and a stable distribution package of Fluentd.
In this blog article, we explains why the concept of channels is introduced.
In the previous versions, td-agent
was shipped as quarterly releases in most cases.
It sometimes contains fluentd minor upgrade occasionally, which means that not only bug or security fixes,
but also contains new features. As a result, there was a case that the stability was affected unexpectedly.
In point view of adopting fluentd (and td-agent
) for enterprise services, there was a requirement for the distribution which contains security or bug fixes only
and scheduled lifecycle of it.
The LTS release is the answer to support them.
There are two channels of support lifecycle.
Here is the difference of these channels.
fluent-package
v6.0.0, and will be shipped in 2025.As for fluent-package v5,
Current releases and future plans:
Release Version | Release Date | End of life |
---|---|---|
v4.5.1 | Aug, 2023 | Dec, 2023 |
v5.0.1 (LTS) | Aug 29, 2023 | March, 2025 |
v6.0.0 (LTS) | March, 2025? (T.B.D.) | T.B.D. |
Happy logging!
