Returns all records from sg_cpu_stats container as list of arrays containing the values in following order:
(user kernel idle iowait swap nice total
context_switches voluntary_context_switches involuntary_context_switches
syscalls interrupts soft_interrupts
systime)in that order without leading headline.
fetchall_table
Returns all records from sg_cpu_stats container as list of arrays containing the values in following order:
(user kernel idle iowait swap nice total
