> We are currently getting the process information from "top". And a given process looks like,
> 28288 gmon      18   0 2225m 277m 8876 S    0  7.0   1:38.56 java
> However, that's still not complete. For it to be truly useful, we would want something like,
> gmon     28288 28244  0 Nov13 ?        00:01:38 /grid/0/java/jdk/bin/java -Xms1000M -Xmx2000M -DAPP=collector

> -DCHUKWA_CONF_DIR=/gri......./../conf -DCHUKWA_LOG_DIR=/grid.........bin/../var/log -classpath
> :/grid..........
> We can get those information by using command below,
