What is td-agent?

Fluentd is written in Ruby for flexibility, with performance sensitive parts written in C. However, some users may have difficulty installing and operating a Ruby daemon.

That’s why Treasure Data, Inc is providing the stable distribution of Fluentd, called td-agent. The differences between Fluentd and td-agent can be found here.

This installation guide is for td-agent v2, the current stable version. See this page for the comparison between v1 and v2. Here is the deb installation guide for v1.

Step 0: Before Installation

Please follow the Preinstallation Guide to configure your OS properly. This will prevent many unnecessary problems.

Step 1 : Install from Apt Repository

For Ubuntu, we currently support “Ubuntu 14.04 LTS / Trusty”, “Ubuntu 12.04 LTS / Precise” and “Ubuntu 10.04 LTS / Lucid”.

For Debian, we currently support Jessie, Wheezy and Squeeze.

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 Trusty,

curl -L | sh

For Precise,

curl -L | sh

For Lucid,

curl -L | sh

For Debian Jessie,

curl -L | sh

For Debian Wheezy,

curl -L | sh

For Debian Squeeze,

curl -L | sh

It’s HIGHLY recommended that you set up ntpd on the node to prevent invalid timestamps in your logs. Please check the Preinstallation Guide.

Step2: Launch Daemon

The /etc/init.d/td-agent script is provided 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 is located at /etc/td-agent/td-agent.conf.

Step3: Post Sample Logs via HTTP

By default, /etc/td-agent/td-agent.conf is configured to take logs from HTTP and route them to stdout (/var/log/td-agent/td-agent.log). You can post sample log records using the curl command.

$ curl -X POST -d 'json={"json":"message"}' http://localhost:8888/debug.test
