Problem this snippet solves:

Continuing on with my series of applications on system level statistics, this application will look into the insides of the global system level statistics for the device. The global statistics contain information on Auth, Bytes, Connections, CPU, Denials, Errors, Hardware, HTTP, Memory, Packets, and the TMM.
