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.
$ gem install arborist-fping
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
