Produce Rundeck compliant node list

README.txt

Stick the PHP file in your Ganglia Web directory. Then in 

$RUNDECK_HOME/projects/Default/etc/project.properties 

add following lines

project.resources.file = /opt/rundeck/projects/Default/etc/resources.yaml
project.resources.url = http://ganglia.local/ganglia/rundeck.php

In Rundeck web UI there will be a link that says

Update nodes for Project Default

rundeck.php

<?php

$conf['ganglia_dir'] = dirname(__FILE__);

include_once $conf['ganglia_dir'] . "/eval_conf.php";

foreach ( $metrics as $node => $metric_array ) {

if ( isset($metric_array['os_name']['VAL']) ) {
