 Basic idea:
     Use the following PS command to gather basic data on processes:
-    ps ax -o pid,ppid,uid,lxc,cuu,rss,times,etimes,stat,command --cols 1000
+    ps ax -o pid,ppid,tgid,uid,lxc,cuu,rss,times,etimes,stat,command --cols 1000
 
     Use resident size as an approximation of real memory usage.
