 * Argument required is json output from logstash.openstack.org's table of metrics. There is no an export option so hack this together by changing the paging size
 * and watch the network traffic in chrome, then save it to a file.
 * Once the file exists, feed it to this script as an argument and it will go through and download all of the log_url items to a directory called 'dump'
 * You should probably mkdir dump/ in the same directory as this script first.
