In the absolutely prototupical way, maybe ten years ago somebody built 
in the system variables function. It was off the plate of the 
developers, then and now, so nobody has cared for or maintained the 
function in the face of continuous development in the more important 
areas. I have strongly argued in the past not to put features like this 
in the public distribution, but to include them in the standard control 
and monitoring (mode 6) protocol. The system variables function was a 
shortcut around that effort and will not be maintained further. 
Meanwhile, consider reporting health data to the clockstats file 
utility, which is what the other drivers do and which is supported.
