Thanks to you I got it . but what should I do when I need to compare between two topologies
I read about tools like ganglia that gave graph about CPU utilization should I use it to make measuring performance easier than numbers And is there specific columns in storm ui that should be greater than other or less than other ? Last question i read that I can measure CPU utilization by capacity column in storm ui But don't know what are numbers should I get . is there specific number that I can compare with it ? Sorry for my lot questions . I made search to get answers for those questions but couldn't get it well Thanks for your time On Tuesday, March 22, 2016, Erik Weathers <[email protected]> wrote: > Not sure what you mean by "it".
