Carol,

Yes, for each feedtype. Each bar represents the number of bytes sent in an
hour.

It represents data-products that were created on Herbie and received by the
LDM on Herbie from the immediate upstream node Herbie.

I know how this could happen but have no idea why Herbie's configured to do
it.

Each color represents a unique <source>_v_<upstream> combination, where
<source> is the name of the host on which the data-products for that 
color were created and <upstream> is the name of the immediate upstream
host from which the data-products for that color were received.

They should be able to check that using 3rd-party switch-monitoring
software pointed at port 388. Because the product-queue will reject a
data-product that it already contains, monitoring port 388 is likely to be
more accurate.
