Overview

The Sensu Graphite Handler is a Sensu Event Handler that sends metrics to the time series database Graphite. Sensu can collect metrics using check output metric extraction or the StatsD listener. Those collected metrics
pass through the event pipeline, allowing Sensu to deliver the metrics to the configured metric event handlers. This Graphite handler will allow you to store, instrument, and visualize the metric data from Sensu.

Asset registration

Assets are the best way to make use of this plugin. If you're not using an asset, please consider doing so! If you're using sensuctl 5.13 or later, you can use the following command to add the asset:

sensuctl asset add nixwiz/sensu-go-graphite-handler

If you're using an earlier version of sensuctl, you can download the asset definition from this project's Bonsai asset index page or releases or create an executable script from this source.

From the local path of the sensu-go-graphite-handler repository:

go build -o /usr/local/bin/sensu-go-graphite-handler main.go

That's right, you can collect different types of metrics (ex. Influx, Graphite, OpenTSDB, Nagios, etc.), Sensu will extract and transform them, and this handler will populate them into your Graphite.
