Enabling vmstat[0-9] or netstat[0-9] graphs in trends page

Hi everyone Has anyone made the vmstat/netstat graphs to work ? At the time, just [vmstat] graph appears in trends page... but if i select the graph manually, it appears correctly... Any idea why ?

Maybe i need to do something in hobbitserver.cfg besides just add 

GRAPHS="...,vmstat2,vmstat3,netstat3,..."

Any help ?

Thank you !

Best Regards,

Giovanni
