This article explains how to install td-agent, the stable Fluentd distribution package maintained by Treasure Data, Inc, on MacOS X.
Fluentd is written in Ruby for flexibility, with performance sensitive parts written in C. However, casual 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.
For MacOS X, we're using the OS native .dmg Installer to distribute td-agent.
Please download the .dmg file from here, and install the software.
You can launch td-agent with launchctl command. Please make sure the daemon started correctly from the log (/var/log/td-agent/td-agent.log).
$ sudo launchctl load /Library/LaunchDaemons/td-agent.plist
$ less /var/log/td-agent/td-agent.log

2013-04-19 16:55:03 -0700 [info]: reading config file path="/etc/td-agent/td-agent.conf"
Your configuration file is located at /etc/td-agent/td-agent.conf. Your plugin directory is at /etc/td-agent/plugin. In case you want to stop the agent, please execute the command below.
$ sudo launchctl unload /Library/LaunchDaemons/td-agent.plist
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
$ tail -n 1 /var/log/td-agent/td-agent.log
