Daniel Lee commented on HTRACE-184:
-----------------------------------
I'm mainly using htrace with the zipkin receiver component and currently the
default processid/ipaddr isn't always good enough. One example of how it's
useful to set processids is when testing I sometimes run several of the same
java program in one ec2 instance and it's impossible to tell them apart without
manually setting processids for every span. ProcessIds are also the default way
of filtering in zipkin's web interface so having more control over them is just
very convenient.
