# Arborist-fping

## Description

Arborist is a monitoring toolkit that follows the UNIX philosophy

of small parts and loose coupling for stability, reliability, and

customizability.

This adds fping sweeping support to Arborist monitoring, providing an

efficient method to check the ICMP reachability of many, many hosts

simultaneously.

It requires the fping binary to be installed in your path.  Use your

package manager of choice.

## Prerequisites

* Ruby 2.4 or better

## Installation

    $ gem install arborist-fping

## Usage

In this example, we're using ICMP reachability as the method to

determine if a host node is available/present on network.

	Arborist::Host( 'example' ) do

		description "Example host"

		address     '10.6.0.169'

	end

From a monitor file, require this library, and exec() to fping.  We'll

record RTT per node in this example with the -e flag, and lower the

timeout-per-host:

	require 'arborist/monitor/fping'

	Arborist::Monitor 'ping check' do

		every 10.seconds

		match type: 'host'

		exec 'fping', '-e', '-t', '150'

		exec_callbacks( Arborist::Monitor::FPing )

	end

That's it.
