need ideas on how to show cluster group tree issue

I think part of why "n/m" is not clear is because it could either mean 
"n out of m" or "n of foo and m of blah). To make it more clear we're 
talking about a fraction, we could use a percentage, e.g,

run.bat   (50%)

Of course, there is still the question "50% of what?". For that part, I 
think a tooltip is essential, e.g. "50% (1 out of 2) JBossAS Server 
members have run.bat child services." I think some sort of icon that 
indicates either "all" or "some" might also help, e.g.:

run.bat   [ICON] (50%)
