== Migration and new vps container ==
When you have this script running in cron on every hardware node and you're migrating a vps container from one node to the other the script will automatically detect this and pick it up on the other node.
When you create a new vps container you have to run <code>ubc_rrd_collect.sh init send</code> and it will ping rddtool to create a new rrd database. It won't overwrite existing databases because it first checks if a database already exists.
