Install by DEB Package (Debian/Ubuntu)
This article explains how to install stable versions of
td-agent deb packages, the stable Fluentd distribution packages maintained by Treasure Data, Inc and Calyptia, Inc..Fluentd is written in Ruby for flexibility, with performance-sensitive parts in C. However, some users may have difficulty installing and operating a Ruby daemon.
That is why Treasure Data, Inc provides the stable distribution of Fluentd, called
td-agent. The differences between Fluentd and td-agent can be found here.Our Calyptia also knows that Fluentd is written in Ruby for flexibility, with performance-sensitive parts in C. However, some users may have difficulty installing and operating a Ruby daemon. And
td-agent is still seated on Ruby 2.7 due to compatibility reasons and Ruby versioning policy, calyptia-fluentd uses Ruby 3 instead of Ruby 2.7 for now.That is why Calyptia, Inc. provides the alternative stable distribution of Fluentd, called
calyptia-fluentd. The differences between td-agent and calyptia-fluentd are bundled and running Ruby versions for now.This installation guide is for
td-agent v3/v4 and calyptia-fluentd v1. td-agent v3/v4 and calyptia-fluentd use fluentd v1 in the core. See this page for the comparison and supported OS.NOTE: Treasure Data does not verify Debian packages. If you have any problem with Debian packages, send a patch to
fluent-package-builder repository.A shell script is provided to automate the installation process for each version. The shell script registers a new apt repository at
/etc/apt/sources.list.d/treasure-data.list and installs the td-agent deb package.For Ubuntu Jammy:

To customize
systemd behavior, put your td-agent.service in /etc/systemd/system.NOTE: In td-agent 4, path is different.
/opt/td-agent/bin instead of /opt/td-agent/embedded/binFor non systemd-based system, use
/etc/init.d/td-agent script to start, stop, or restart the agent:$ sudo /etc/init.d/td-agent restart
$ sudo /etc/init.d/td-agent status
td-agent (pid 21678) is running...
The following commands are supported:
$ sudo /etc/init.d/td-agent start
$ sudo /etc/init.d/td-agent stop
$ sudo /etc/init.d/td-agent restart
$ sudo /etc/init.d/td-agent status
Please make sure your configuration file path is:
/etc/td-agent/td-agent.conf
The default configuration (
/etc/td-agent/td-agent.conf) is to receive logs at an HTTP endpoint and route them to stdout. For td-agent logs, see /var/log/td-agent/td-agent.log.You can post sample log records with
curl command:$ curl -X POST -d 'json={"json":"message"}' http://localhost:8888/debug.test
$ tail -n 1 /var/log/td-agent/td-agent.log
