Resolution:
For UNIX, TIB/Hawk HMA (binary name tibhawkhma) should be setuid and owned by root. This binary should have the privileges to access the processes run on the system. System kernel information requires root access in order to become "visible". And hawk is designed to monitor system kernel information.
If this is not done correctly, it defeats the purpose of hawk monitoring.
Once that's done, you may run it as an user but the effective user becomes root which allows you to see other processes owned by root when using
getProcess method.
