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:
