OK.

re:
> Since we only run mcidas, how do we tell whether we are Requesting the data

Login to your downstream box, noaapxcd, as the user 'ldm' (assuming, of
course that you are running the LDM as the user 'ldm' and then run the 
following:

cd ~ldm
grep -i ^request etc/ldmd.conf

This will list back each REQUEST line in your LDM configuration file, 
~ldm/etc/ldmd.conf
that is uncommented.  The set of REQUESTs should answer the question if you
are, indeed, REQUESTing the data from your upstream machine, noaapnew.

re:
> and if we are how would we look at the data in mcidas (adde) for example the 
> NIMAGE data.

The pieces that must be in place for you to look at the data in McIDAS
using ADDE are:

1) REQUEST the data in the LDM setup

   After the needed REQUEST lines are included in your ~ldm/etc/ldmd.conf
   file AND the LDM has been restarted so that those lines are activated,
   you can use the LDM utility 'notifyme' to see if you are receiving the
   data:

<as 'ldm'>
notifyme -vl- -f NGRID -o 3600
notifyme -vl- -f NIMAGE -o 3600
...

Or,
notifyme -vl- -o 3600

2) process the data REQUESTed

   This is done by action(s) in one or more LDM pattern-action files.  If
   your LDM setup for McIDAS followed the recommendations listed in the
   Unidata McIDAS-X User's Guide, you should have file following files
   in your ~ldm/etc directory:

   pqact.conf_mcidasA
   pqact.conf_mcidasB

   And, you should have EXEC lines in your LDM configuration file,
   ~ldm/etc/ldm.conf, that run 'pqact' invocations using these
   pattern-action files.  The LDM pattern-action files, LDM configuration
   file entries and 'ldm' crontab entries are created when the 'mcidas'
   user runs the 'mcxconfig' script from the $MCDATA directory of the
   'mcidas' account:

<login as 'mcidas' on noaapxcd>
cd $MCDATA
mcxconfig

 -- answer questions about which datastreams you want to configure
    for use

 NB: three different directories will need to be writable by 'mcidas'
 for the script to function fully/properly:

 - the directory in which McIDAS decoding will occur
 - the HOME directory of 'ldm'
 - the ~/etc directory of 'ldm'
  This example has the
   NIMAGE data being processed by the pqact invocation that is using
   the pqact.conf_mcidasA pattern-action file, but it does not contain
The EXEC lines that the person configuration things for McIDAS XCD
decoding will have to include in ldmd.conf will look something like:

exec    "pqact -f IDS|DDPLUS|HRS|NGRID|HRS|NGRID|FNEXRAD|NIMAGE 
etc/pqact.conf_mcidasA"
exec    "pqact -f FSL2|NLDN|NNEXRAD|UNIWISC etc/pqact.conf_mcidasB"

   I say "something like" because the set of datastreams included in
   the '-f' option to pqact can vary. What you may find on your system
   depends on how the person who setup the decoding (Martha?) choose to
   do things (sorry, I don't know what this is)

3) ADDE dataset definitions will have to have been created so that the
   data files processed by the LDM actions in 2) can be found and
   served

4) remote ADDE access may or may not need to be setup

   If you are only using the data from the 'mcidas' account on the
   noaapxcd machine, then remote server access does not need to be
   setup/configured.  If you want to access the data served by
   ADDE from an account other than 'mcidas' on noaapxcd or from
   some other machine, then the remote ADDE access needs to be
   setup

I don't know how things are configured there, so I can't provide more
specific information on what may or may not need to be done.

Cheers,

Tom
