The missing data problem seems to be fixed. I noticed that rcz006.ust.hk started reporting real time statistics for IDS|DDPLUS products yesterday: http://www.unidata.ucar.edu/staff/chiz/latency/rtstats/index2.shtml?rcz006.ust.hk The latencies for the observational products in this stream are now virtually zero which means that you are getting them within a second or so of their being injected into the IDD. Not bad for communications half way around the world! >But when I added the line > > exec "rtstats -h rtstats.unidata.ucar.edu" > >to the etc/ldmd.conf file.

I would suspect a name lookup problem. You could replace the fully qualified hostname in the rtstats line with the IP address for flip (128.117.140.85), but when we move the rtstats server to a new machine, your reporting would break. It is curious that stats for IDS|DDPLUS are coming through but the same for the HDS feed are not. I can't explain this, but I would be tempted to review the entries you made in your ldmd.conf file to make sure that there are no typos. I would also try to verify that you are, in fact, receiving and filing the HDS products with no problems. Lastly, keep an eye on the log messages in ldmd.log*. Cheers, Tom
