Learn about the Wavefront Fluentd Integration.

Fluentd Integration

Fluentd is an open source data collector for a unified logging layer. This integration installs and configures Telegraf to send Fluentd metrics into Wavefront. Telegraf is a light-weight server process capable of collecting, processing, aggregating, and sending metrics to a Wavefront proxy.

In addition to setting up the metrics flow, this integration also installs a dashboard. Here’s a section of a dashboard displaying Fluentd metrics:


To see a list of the metrics for this integration, select the integration from https://github.com/influxdata/telegraf/tree/master/plugins/inputs.

Fluentd Setup

This integration uses Telegraf’s Fluentd input plugin to fetch the metrics from Fluentd and push them to Wavefront.

Step 1: Install the Telegraf Agent

Log in to your Wavefront instance and follow the instructions in the Setup tab to install Telegraf and a Wavefront proxy in your environment. If a proxy is already running in your environment, you can select that proxy and the Telegraf install command connects with that proxy. Sign up for a free trial to check it out!

Step 2: Ensure the monitor_agent plugin is configured on Fluentd

In the Fluentd configuration file /etc/td-agent/td-agent.conf, ensure that the monitor_agent plugin is configured as in the example below:

    @type monitor_agent
    port 24220

Step 3: Configure the Fluentd Input Plugin on Telegraf

Create a fluentd.conf file in /etc/telegraf/telegraf.d and enter the Fluentd plugin configuration as in the following example snippet:

# Read metrics exposed by fluentd monitor_agent plugin
  ## This plugin reads information exposed by fluentd (using /api/plugins.json endpoint).
  ## Endpoint:
  ## - only one URI is allowed
  ## - https is not supported
  endpoint = "http://example.com:24220/api/plugins.json"

  ## Define which plugins have to be excluded (based on "type" field - e.g. monitor_agent)
  exclude = [

Step 4: Restart Telegraf

Run sudo service telegraf restart to restart your Telegraf agent.
