How to " Clear all traffic counter from CLI"

[Fortiswiss]

I tried to find information to clear all traffic counters of a VDOM There is a description on the GUI: http://kb.fortinet.com/kb/microsites/microsite.do?cmd=displayKC&externalId=FD32921 but this needs to be done for each policy... How can I do this for a whole VDOM? Thanx for any hint...

Open a case, in the pass  FortiOS version it used to work flawlessly. What I do is to grab the  fwpolicy.ID# and  rust run them thru a for loop and clear each ID.
