Sensu Graphite Handler

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.

Installation

Download the latest version of the sensu-go-graphite-handler from bonsai, 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

Configuration

Example Sensu Go handler definition:

{
    "api_version": "core/v2",
    "type": "Handler",
    "metadata": {
        "namespace": "default",
        "name": "graphite"
    },
    "spec": {
        "type": "pipe",
        "command": "sensu-go-graphite-handler",
        "timeout": 10,
        "filters": [
            "has_metrics"
        ]
    }
}

Example Sensu Go check definition:

{
    "api_version": "core/v2",
    "type": "CheckConfig",
    "metadata": {
        "namespace": "default",
        "name": "dummy-app-prometheus"
    },
    "spec": {
        "command": "sensu-prometheus-collector -exporter-url http://localhost:8080/metrics",
        "subscriptions":[
            "dummy"
        ],
        "publish": true,
        "interval": 10,
        "output_metric_format": "influxdb_line",
        "output_metric_handlers": [
            "graphite"
        ]
    }
}

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.
