The two bolts that emit and transfer 0 are most likely your persistantAggregates. They're sinks, so they don't emit or transfer anything.
I forget the exact definition of capacity, but it indicates when that bolt is taking too long to process. If it's greater than one, it's a bottleneck. Its something like the percent of time a worker so processing that bolt. (It can be greater than one so it might be percent of time over all workers... Unclear) -Cody On May 20, 2014 4:32 PM, "Raphael Hsieh" <[email protected]> wrote: > > Hi I'm confused as to what each field in the StormUI represents and how to use the information. > > The bolts I have above are formed from trident.
