serf-td-agent

td-agent process management with serf

Installation

Assume you have installed td-agent.

Use fluent-gem:

fluent-gem install serf-td-agent

The serf command is automatically downloaded and bundled into the bin directory of the gem. Also, serf-td-agent command, which is a serf event handler, is located at there. Set the environment variable PATH as:

export PATH=$(fluent-gem path serf-td-agent)/bin:$PATH

How to setup the serf cluster

Run the first serf at any of hosts running td-agent like:

$ serf agent -event-handler=serf-td-agent

Run later serfs at other hosts running td-agent like:

$ serf agent -join={the first serf address} -event-handler=serf-td-agent

Hint: -log-level=debug option would be helpful for debugging.

How to restart td-agent via serf

Send a serf event from any of hosts running the serf like:

$ serf event td-agent-restart

This will propagate the td-agent-restart event to the entire serf cluster and execute sudo /etc/init.d/td-agent restart at all hosts.

Available events

Following events are available:

  • td-agent-start
  • td-agent-stop
  • td-agent-reload
  • td-agent-restart
  • td-agent-condrestart
  • td-agent-status
  • td-agent-configtest

which corresponds with /etc/init.d/td-agent command.
