>                 URL: https://issues.apache.org/jira/browse/HADOOP-5385
>             Project: Hadoop Core
>          Issue Type: New Feature

> 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
> -Dlog4j.configuration=chukwa-log4j.properties -DCHUKWA_HOME=/gri........
> -DCHUKWA_CONF_DIR=/gri......./../conf -DCHUKWA_LOG_DIR=/grid.........bin/../var/log -classpath
> :/grid..........
> We can get those information by using command below,
>         ps axo pid,user,vsize,size,pcpu,pmem,time,start_time,start,cmd
