Learn about the Wavefront Twemproxy Integration.

Twemproxy Integration

Twemproxy (nutcracker) is a fast and lightweight proxy for memcached and redis. This integration installs and configures Telegraf to send Twemproxy 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 are the Overview and Pool Stats sections of a dashboard displaying Twemproxy metrics: images/twemproxy_dashboard.png

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

Twemproxy Setup

Step 1. Install the Telegraf Agent

This integration uses the Twemproxy input plugin for Telegraf to extract metrics from Twemproxy.

Note: Install the Telegraf agent on the Twemproxy host.

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. Enable the Twemproxy input plugin

Create a twemproxy.conf file in /etc/telegraf/telegraf.d and add the following snippet:

    ## Read Twemproxy stats data
    [[inputs.twemproxy]]
      ## Twemproxy stats address and port (no scheme)
      addr = "localhost:22222"
      ## Monitor pool name
      pools = ["redis_pool", "mc_pool"]

Step 3. Restart Telegraf

Run sudo service telegraf restart to restart your Telegraf agent.
