As the LDM 6 is currently, the only way to get an upstream LDM 6 to log
data-product metadata upon transmission is to put the process into
"debug" logging (e.g., by sending the process two USER2 signals).  This
has the unfortunate effect of logging too much information.

One can use the "ldmadmin watch" capability to monitor what data
products arrive in the queue.

One can also use the rtstats webpage at

    <http://www.unidata.ucar.edu/staff/chiz/rtstats/>

to monitor performance.

The webpage

    
<http://my.unidata.ucar.edu/content/software/ldm/ldm-6.0.14/basics/monitoring.html>

contains information on monitoring LDM performance.

Brain damage?  :-)

Seriously, I'm thinking about adding this capability to the LDM 6 code
(the lack of this capability bit me in the LDM workshop I just gave).
