Yes I did, however the default MRTG configuration appears to contain almost nothing. Consulting with others. it seems to be the norm, MRTG should pick up the standard OIDs for the basics, i.e. load and network traffic if nothing's specified. Currently, I had to manually insert target lines after figuring out the OIDs in order to get garbage data into the log files. Garbage data because while the debug log shows some numbers corresponding to output from top, MRTG is producing graphs that bear no resemblance to it. Reproducing the entire default MRTG configuration would therefore pretty much require a very long config file, as well as coming up with formulas to twist the data into something that would produce sensible graphs... which obviously don't seem like the right way to do it.
