Neil,
My mistake, file action must be uppercase, ie FILE.
WMO ^metar (....) ([0-3][0-9])([0-2][0-9])
FILE /data/ddplus/(\2:yy)(\2:mm)\2\3.wmo
The metars products arrive at a rate of 1 a sec. You can scan
the queue looking for product via pqcat, ie
% pqcat -vl - -q <yourPQSURFqueue> > /dev/null
For more info on pqcat look at:
