getsystemcpu & related commands always return 0 cpu usage

It seems that OAM is parsing the wrong field somewhere when gathering CPU usage info. It affects the getsystemcpu command, and others that return overall CPU usage. Those commands always return 0% cpu usage even when I load them down with dummy processes (ex, some bash that does useless stuff in an infinite loop).

I suspect this is consistent across environments, but fwiw, the environment I found this in is a DBS-like installation. Centos 7 VMs. Originally installed 1.1.6 non-distributed and non-root. Then upgraded to 1.2.1 with non-root/non-sudo/non-distributed. 2 nodes, 1 um, and 1 pm.
