sensu-influx-handler

A listener to take sensu metrics events on a TCP socket, and post them to InfluxDB

Motivation

If you want to use Sensu as your monitoring router, you still need to send the metrics somewhere.
InfluxDB is a good choice for this, but if you have a large number of metrics, forking a handler (using the pipe type) will be non-performant.

This small application is meant to run as a daemon, listening on a TCP port, for metrics events from Sensu.

Installation

You can use the pre-built binaries, or follow the instructions in the Compilation section to build yourself.

This process should be managed by something like supervisord.

Be sure to create an appropriate config file for your environment. The environment is specifed using the SENSU_INFLUX_MODE environment variable. For instance:

SENSU_INFLUX_MODE=production ./sensu-influx-handler 

This will start the app listening on the port specified in the config file.

Configuration

The configuration file used depends on the environment specified:

SENSU_INFLUX_MODE value	config file used
(none)	./sensu-influx.local.conf
staging	./sensu-influx.stg.conf
production	./sensu-influx.prod.conf

The configuration file should be in the following format:

[influxdb]
host = localhost:8086
username = admin
password = admin
database = test
isSecure = no
isUDP = no

Then, configure a handler in Sensu, such as this /etc/sensu/conf.d/handler_influxdb.json:

{
  "handlers": {
    "influxdb": {
	  "type": "tcp",
      "socket": {
	    "host": "localhost",
    	"port": 3333
      }
    }
  }
}

Compilation

• To build it for your local system:

  	godep go build
  

• To cross-build:

    goxc
