Hi users!
We have released fluent-package v5.2.0. fluent-package is a stable distribution package of Fluentd. (successor of td-agent v4)
This release is a new release of v5.2 series.
GEM_HOME/GEM_PATH in fluentd.batPreviously, when upgrading the fluent-package, you had to stop the fluentd service, install the new version of the fluent-package, then install any necessary plugins, and finally restart the fluentd service.
Starting from fluent-package v5.2.0, we have introduced the zero-downtime restart feature that automatically installs the required plugins during the upgrade process and allows you to upgrade Fluentd without interrupting the logging service.
Please refer to "Advisory for upgrading with zero-downtime".
In the previous versions of msgpack gem, there was a possibility that cause DoS (Denial Of Service) when crafted message was sent to Fluentd.
When that message was sent, it might cause "NoMemoryError" on Fluentd because there is a case that msgpack try to pre-allocate huge amount of memories.
Above behavior was fixed not to pre-allocate over 32k entries (limit pre-allocated amount of memories) in msgpack 1.7.3 and bundled.
GEM_HOME/GEM_PATH in fluentd.batIn the previous versions, fluentd.bat doesn't set GEMHOME/GEMPATH explicitly.
If users set custom GEM_HOME / GEM_PATH environment variables, the
batch file will not work as expected. Therefore, this patch will set
the appropriate values in the batch file.
We have changed so that Fluentd does not restart when the needrestart package is installed.
fluent-package v5.2.0 places /etc/needrestart/conf.d/50-fluent-package.conf.
In this release, the bundled fluent-plugin-systemd was updated to 1.1.0. That release fixed SIGABORT error with inconsistency of memory allocator handling.
The zero-downtime restart feature can be configured by FLUENT_PACKAGE_SERVICE_RESTART environment variable.
Please refer to following section for more details.
FLUENT_PACKAGE_SERVICE_RESTART environmental variable
FLUENT_PACKAGE_SERVICE_RESTART environment variable.FLUENT_PACKAGE_SERVICE_RESTART environmental variableWe have introduced FLUENT_PACKAGE_SERVICE_RESTART environment variable to configure the zero-downtime restart feature.
The variable exists in the following file:
/etc/sysconfig/fluentd/etc/default/fluentdExample:
FLUENT_PACKAGE_OPTIONS=""
# Control method to upgrade service (auto/manual) restart
FLUENT_PACKAGE_SERVICE_RESTART=auto
The service automatically restarts with zero-downtime restart feature when all of the following conditions are met:
The plugins will be automatically reinstalled if needed if your environment has an active online connection. For more details, please refer to "Automate Plugin Install for Update on Demand".
You can use this approach if you prefer to manage plugins manually or if your environment does not have offline connection. If the service was active before the update, it will not restart automatically with this configuration. You need to restart the service manually.
SIGUSR2 signal to the supervisor process, such as with kill -USR2 <PID>systemctl restart fluentd.If you prefer to manage plugins automatically, please set FLUENT_PACKAGE_SERVICE_RESTART to auto (default).
When the service restarts automatically using the zero-downtime restart feature, any missing plugins are automatically detected and reinstalled before the restart.
Previously, automatic restarts after updates were not recommended due to potential issues. If you manually install plugins, you need to reinstall them before restarting when the embedded Ruby version is updated.
To address this, this feature enables automatic plugin installation during the restart process. The steps are as follows:
fluent-plugin- prefix.If you prefer to manage plugins manually, please set FLUENT_PACKAGE_SERVICE_RESTART to manual.
This is useful in cases such as:
In this mode, automatic plugin installation and restarts are disabled.
You can manually install plugins and send a SIGUSR2 signal to trigger the zero-downtime restart feature after the update.
If you use a custom unit file, such as /etc/systemd/system/fluentd.service, please remove these 2 lines.
Environment=GEM_HOME=/opt/fluentd/lib/ruby/gems/...
Environment=GEM_PATH=/opt/fluentd/lib/ruby/gems/...
We don't need GEM_HOME and GEM_PATH.
They will be removed after v5.2.0, but if you use a custom unit file, you need to remove them manually.
If these variables are set, the zero-downtime restart feature may not work correctly.
It is because the new process inherits the original environment variables if using this feature.
Please refer to #713 for more details.
Please see the download page.
We plan to ship the next LTS version of fluent-package v5.0.6 on March, 2025. The content of updates are still in T.B.D.
As it was already announced Drop schedule announcement about EOL of Treasure Agent (td-agent) 4, td-agent v4 was reached EOL in Dec, 2023.
After reached EOL, td-agent v4.5.3 on Windows was released because there was a crash bug during startup on Windows. It was backported fix from fluent-package v5 as it is critical in some case. Even though this was a exceptional maintenance release, but there is no change to the fact that we already stopped maintaining td-agent v4.
We strongly recommend migrating from td-agent v4 to fluent-package v5 (LTS). See Upgrade to fluent-package v5
Hi users!
We have released fluent-package v5.0.5. fluent-package is a stable distribution package of Fluentd. (successor of td-agent v4)
This is a maintenance release of v5.0.x LTS series. As bundled Ruby was updated to 3.2.6 and Fluentd was updated to 1.16.6. We recommend upgrading to fluent-package v5.0.5!
In this release, focused on updating bundled ones.

Hi users!
We had launched fluent-package v5 series last year, recently shipped v5.0.4 in LTS release channel and
v5.1.0 in normal release channel.
In this blog article, we explains the planned next major updates - v6.0.0.
In short, we will ship fluent-package v6 in Aug, 2025.
We keeps two release channels as follows:
Here is the difference of these channels.
fluent-package v7.0.0, and will be shipped in 2027 (T.B.D.).As for fluent-package v6,
Current releases and future plans:
| Release Version | Release Date | End of life |
|---|---|---|
| v5.0.x (LTS) | Aug, 2023 | Dec, 2025 |
| v6.0.0 (LTS) | Aug, 2025 | Dec, 2027 (T.B.D.) |

Happy logging!
Hi users!
We have released fluent-package v5.1.0. fluent-package is a stable distribution package of Fluentd. (successor of td-agent v4)
This release is a new release of v5.1 series. Bundled ruby version was upgraded to 3.2.5 and fluentd v1.17.0 was shipped!
In this release, focused on updating bundled ones.
In LTS version, conservative updating policy is enabled, so updating gem is very limited to bug fix or security fix. In contrast to LTS version, v5.1.0 bundles more recent components because of standard version.
As we already announced in Scheduled support lifecycle announcement about Fluent Package blog article, in normal release channel, we will ship the latest version (v1.17.0) of Fluentd.
So if you want to try using latest version of Fluentd, v5.1.0 is one for you. If you use fluent-package in enterprise services, keep using fluent-package 5.0.x (LTS).
Please see the download page.
We plan to ship the next LTS version of fluent-package v5.0.5 on Oct, 2024. The content of updates are still in T.B.D.

Hi users!
We have released fluent-package v5.0.4. fluent-package is a stable distribution package of Fluentd. (successor of td-agent v4)
This is a maintenance release of v5.0.x LTS series. As bundled Ruby was updated to 3.2.4 and a foolproof mechanism was implemented to prevent launching duplicated Fluentd instances, we recommend upgrading to fluent-package v5.0.4!
In this release, a foolproof mechanism was implemented to prevent launching Fluentd wrongly if the service is already running.
As you know, you can check the version of Fluentd with fluentd --version, but there is a case that fluentd -v is executed wrongly to
do it.
When already running Fluentd as a service, fluentd -v launches a duplicated Fluentd instance with the same fluentd configuration.
If you launch duplicated Fluentd instances, it causes the corruption of processing Fluentd buffer.
To prevent such a situation, a foolproof was implemented now.
For example, if Fluentd is running as a service, launching Fluentd causes an error to block it.
Here is the example on Windows:
> fluentd
Error: Can't start duplicate Fluentd instance with the default config.
To start Fluentd, please do one of the following:
(Caution: Please be careful not to start multiple instances with the same config.)
- Stop the Fluentd Windows service 'fluentdwinsvc'.
- Specify the config path explicitly by '-c' ('--config').
Even though if you wrongly launch Fluentd to check version with -v (It should be --version to show version), then it causes the following error.
> fluentd -v
Error: Can't start duplicate Fluentd instance with the default config.
To take the version, please use '--version', not '-v' ('--verbose').
To start Fluentd, please do one of the following:
(Caution: Please be careful not to start multiple instances with the same config.)
- Stop the Fluentd Windows service 'fluentdwinsvc'.
- Specify the config path explicitly by '-c' ('--config')
Note that this foolproof feature is intended to block launching duplicated Fluentd instance, you can explicitly launch Fluentd by specifying a specific option to pass it even though already Fluentd is running as a service.
On Windows:
-c (--config)--dry-run--reg-winsvc--reg-winsvc-fluentdopt--show-plugin-configOn Linux:
-c (--config)--dry-run--show-plugin-configWe plan to ship the next LTS version of fluent-package v5.0.5 on Oct, 2024. The content of updates are still in T.B.D.

Hi users and developers!
We would like to share the information about an event appearance of Fluentd maintainers.
Daijiro Fukuda and Kentaro Hayashi, Fluentd Maintainers from ClearCode Inc., are going to talk at the Open Source Summit Japan on December 5th
The event has been taken thousands of attendees all over the world and one of the leading Open Source event in Japan. We are honored to take this opportunity and very excited to share about Fluentd project at the conference!
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!

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,
| Release Version | Release Date | End of life |
|---|---|---|
| v4.5.1 | Aug, 2023 | Dec, 2023 |
| v5.0.1 (LTS) | Aug 29, 2023 | Dec, 2025 |
| v6.0.0 (LTS) | Aug, 2025? (T.B.D.) | T.B.D. |
Happy logging!
fluent-package "v5" is available since August 2023.
fluent-package is the successor of td-agent "v4".
In this post, we will share the steps we've tested and hopefully this will help your experience from v4 to v5.
fluent-package was formerly known as td-agent.
In the past, Treasure Data, Inc took the initiative to provide the package, but now the Fluentd community does it. This is why the package name was changed.
To represent "All in one package of Fluentd which contains Fluentd and related gem packages", the package name was changed to fluent-package.
Even though package name was changed, Treasure Data, Inc still sponsor the package delivery resources.
There are two channels for fluent-package.
One is normal release version which will be updated regularly - rapid release development style (td-agent v4 was released like this in almost every quarter).
In this version, fluentd will be eventually updated to newer minor version (e.g. 1.17.x and so on)
The other is a more conservative maintenance version (Long Term Support) which will not introduce a new feature. It only applies teeny update such as security or bug fix only. LTS for v5 will be supported until March, 2025.
More details about difference between normal release version and LTS version will be explained in Scheduled support lifecycle announcement about Fluent Package.
In the fluent-package v5, core components like ruby (2.7.8 -> 3.2.2) and OpenSSL (1.1.1 -> 3.1.0 for Windows, 3.0.8 for macOS) were updated.
The major changes are as follows.
td-agent command is renamed to fluentd.
$ td-agent --version -> $ fluentd --versiontd-agent-gem command is renamed to fluent-gem.
$ td-agent-gem list -> $ fluent-gem listtd-agent is renamed to fluentd.
$ systemctl status td-agent -> $ systemctl status fluentdWith the change of package name, install path, service name (e.g. /opt/fluent, fluentd.service) and so on were also changed.
Basically, for td-agent v4 users, it aims to keep compatibility as far as possible by executing the migration process with copying old files or providing
symbolic links for it.
If you want to know the details of upgraded components, see CHANGELOG.md.
NOTE: We explain for platform specific issue as "Additional hints for v4 users" section below.
During the upgrade process, plugins bundled in td-agent are automatically upgraded. With that being said, other plugins added on your own are not included. You should review if you need to upgrade plugins since some directory structures from v4 and v5 are changed.
In this post, I will show steps with plugins added on my own, "fluent-plugin-concat" for instance. Here is sample configuration file I used through steps.
