Interpreting the log file is complicated by the number of processes writing to 
it.  As far as Dataportal is concerned, however, most of the entries are like 
this:

Apr 14 21:50:11 tigge-ldm dataportal[15562] INFO: Connection from 
dataportal.ucar.edu
Apr 14 21:50:12 tigge-ldm dataportal(feed)[15562] NOTE: Starting Up(6.4.5.1/6): 
20060414205011.023 TS_ENDT {{ANY, "^z_tigge_c_ecmf.*
\.grib:.*(11|31|51|71|91)$"}}, Primary
Apr 14 21:50:12 tigge-ldm dataportal(feed)[15562] NOTE: topo: 
dataportal.ucar.edu {{ANY, (.*)}}

(Thank goodness for grep(1) ! :-)

There are 19 entries like the above -- corresponding to the 19 patterns 
requested by Dataportal.  Therefore, your LDM system appears to be working (at 
least as far as Dataportal is concerned).
