> Looks like the current approach for collecting process metrics (CPU, RSS, SWAP) is not
portable across different flavors of Linux. The agent currently collects some of the process
stats from /proc/<pid>/statm file but it looks like the syntax of this file is OS specific
thus current approach is not working right. 
> There is some evidence that on RedHat the stats for RSS and Swap are wrong. 
> Change agent's code to collect process stats from ps command
