      From 1.3.1 onwards verbosegc option only provide the
      following type of information:
      GC 129114K-99185K(260992K), 0.0287809 secs
      Full GC 127643K-99265K(260992K), 3.8968919 secs

      According to SUN's doc "Interpreting -verbosegc Output":
      (http://docs.sun.com/db/doc/806-1367/6jalj6mv5? a=view) using command
      "-verbosegc -verbosegc" should give more info than above. Examples:

      Gen0(semi-spaces); size=4096kb, free=0kb, maxAlloc=0kb
       From space; size=524288 words, used=524286 words, free=2
      To space; size=524288 words, used=1 words, free=524287
      Gen0(semi-spaces)-GC #4 tenure-thresh=0 61ms 0%-28% free
      Gen0(semi-spaces); size=4096kb, free=571kb, maxAlloc=571kb
       From space; size=524288 words, used=378157 words, free=146131
      To space; size=524288 words, used=1 words, free=524287
      Gen1(mark-compact); size=4096kb, free=0kb, maxAlloc=0kb
      Gen1(mark-compact)-GC #1 Gen1: 850kb dense
      262ms 0%-2% free
      Gen1(mark-compact); size=4096kb, free=80kb, maxAlloc=80kb

      Also, adding the start timestamp and elapsed time would be most useful.
