XF 2.0 How to Show Linux Server Load on Admin Page

Generally if I want to view the load of my Linux server then I can just do this in PHP code:

Code:
print_r(sys_getloadavg());

But to make life easier I'd quite like to add this to XenForo's main admin.php home page, does anybody have any idea how I can add this output to that page? Maybe under the new 'Server environment report' summary or within it.
