Hi Phil,

The creation and deliver of GOES-East sectors in the Unidata-Wisconsin
datastream (IDD feedtype UNIWISC aka MCIDAS) does seem a bit slower
lately. We will investigate...
re:
>Here's our LDM request...
Your LDM pattern-action set looks OK. If the machine you are running
your LDM on is twister.sbs.ohio-state.edu, then your UNIWISC latencies
are, for the most part, low enough to not account for a delay in
receipt of a half hour:

The other thing to check is if your machine is behind in processing
products it has received out of its LDM queue. Look for messages in
your LDM log file, ~ldm/etc/ldmd.log, that indicate slow processing
(e.g., slow writes). If you are seeing messages like this in your LDM
log file, please open an inquiry with Unidata IDD Support, by sending
an email to: support-idd@xxxxxxxxxxxxxxxx.
re:
>Let me know if anyone has any suggestions - or perhaps a
>better way to structure the LDM request...
Two small comments:
- your FILE actions are as efficient as the can be
- the listing you include below is for your LDM pattern-action file
actions, not the request for the data. The request will be found in
your LDM configuration file, ~ldm/etc/ldmd.conf. Look for a 'REQUEST'
line for the UNIWISC datastream, and be aware that you may be using
MCIDAS as the feedtype (MCIDAS is the old name for the UNIWISC feed,
but it still recognized by he LDM).

Which site(s) are you referring to?
