There's a Cron-Like scheduler being done for the Command Line MP, but I 
don't think it will be out before the end of the month. Although most 
that it needs right now is the official definition of the messages, but 
with the perfSONAR release process I don't think this will be done so 
soon. We also developed an external tool for storing scheduled data 
result in SQL MA. There's no tool that shows this type of data yet 
(OWAMP, BWCTL, ping or traceroute measurements can be done by the CL-MP).
