Jerry Cwiklik updated UIMA-4826:
--------------------------------
Description:
When collecting user processes the Agent spawns ps command and gathers results.
Under some circumstance the OS ps command may not provide correct results.
Sometimes it returns user id instead of user name.
User id is a numeric value. Add a check to see if the ps returned a numeric
value and if so convert it to username by running
getent passwd <uid> | cut -d ':' -f 1

When collecting user processes the Agent spawns ps command and gathers results.
Under some circumstance the OS ps command may not provide correct results for
user id. Sometimes it returns user id instead of user name.
Modify the ps command to use
pb = new ProcessBuilder("ps","-Ao","user:12,pid,ppid,uid,user:12,args",
"--no-heading");
upon return check result of parse and compare user[0] to user[4]. Both should
match. If different dont collect user data and do another ps command.
As an extra check, make sure the user is not uid. If is all numeric, throw away
results and try again.
