Removing a node from the Ganglia Web Frontend

According to the Ganglia_Readme, there is not easy way to remove a single dead node from the list from the ganglia web front-end. To flush the dead node from the record by restarting the the gmetad and gmond processes, you have to add the line at /etc/gmond.conf

globals { 
host_dmax = 3600 
}

The hosts will be removed from host tables when they haven't been heard from in 3600 seconds. See "man gmond.conf" for details.
