Carol, When a data-product is created, its "origin" field is set to the hostname of the local host. When the data-product is first inserted into the LDM product-queue its origin field will have this value. Whenever a downstream LDM receives a data-product and before it inserts the data-product into the product-queue, it modifies the product's origin field by either appending the string "_v_<upstream>" (where <upstream> is the name of the host from which the product was received) or modifying that suffix to reference the upstream host if the suffix already exists. The fact that the origin field in question has the value "herbie-amrc.ssec.wisc.edu_v_herbie-amrc.ssec.wisc.edu" means that those data-products were created on Herbie and received by a downstream LDM on Herbie from an upstream LDM on Herbie. This could happen if Herbie's LDM configuration-file contained a REQUEST entry for products from Herbie. Why one would want to do this is beyond me. I note, however, that this only occurred during one hour. Perhaps someone was fiddling with the configuration-file? > I was thinking more about the > herbie-amrc.ssec.wisc.edu_v_herbie-amrc.ssec.wisc.edu bar in the plot. > > http://rtstats.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?EXP+herbie-amrc.ssec.wisc.edu > > Are these simply products that are created on herbie and inserted into > herbie's queue?

The data that is created on herbie is sent every hour and the > amount of data is about 35 KBs.
