Learn about the Wavefront ZooKeeper Integration.

ZooKeeper Integration

ZooKeeper is a centralized service for maintaining configuration information, providing distributed synchronization and providing group services. This integration installs and configures Telegraf to send ZooKeeper server 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 preview of some charts in the ZooKeeper dashboard.

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

ZooKeeper Setup

Step 1. Install the Telegraf Agent

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

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 ZooKeeper input plugin

Create a file called zookeeper.conf in /etc/telegraf/telegraf.d and enter the following snippet:

	# # Reads `mntr` stats from one or many zookeeper servers
	[[inputs.zookeeper]]
	#   ## An array of addresses to gather stats about. Specify an IP or hostname
	#   ## with port e.g. localhost:2181, 10.0.0.1:2181, etc.
	#
	#   ## If no servers are specified, then localhost is used as the host.
	#   ## However, don't leave the server blank as the metric generated will 
	#   ## contain an invalid value for the `server` point tag and be blocked by the Wavefront proxy.
	#   ## If no port is specified, 2181 is used
	  servers = ["<server>:<client port>"]
	  fielddrop = ["version"]

Step 3. Restart Telegraf

Run sudo service telegraf restart to restart your Telegraf agent.
