Hello,

Thanks for that. It was just what I wanted.

Turns out that the error I'm getting is 'No DS called 'in' in
'ifstat.eth0.rrd'. However, my test is called 'if', not 'ifstat'.

It seems that the entry I had in graphs.cfg was 'FNPATTERN
^if.(.+).rrd' (which would match the previous 'ifstat' entry). Changing
my pattern to '^if\.' sorted out the problem :-)

Now I have to work out why the one graph for one client I did have for
the 'if' test appeared - it seems that the client has no 'Network
traffic' graphs at all (or RRD files) so something with the netstat or
ifconfig data must be causing a problem. (Both do exist in the client
data.)
