Thanks Kevin.

That sounds like it would work. I have RRD installed already as I played
around with Cricket a while back. I added the line to the mrtg config file
to convert to rrd, so I will play around with that.

The multiple SNMP queries I was talking about, I was not using rrd at the

One SNMP query would generate a small 130x80 graph using xsize/ysize then
another SNMP query would generate a regular size graph.

Not very efficient.

Thanks for the reply.
