  Node ID
• measurement_id
  Measurement sequence ID; later measurements have lower IDs
• cpu_no
  CPU ID
• cpu_online
  1 if the CPU is currently online, otherwise 0
• cpu_userspace_time
  CPU time spent in userspace
• cpu_idle_time
  CPU time spent idle
• cpu_system_time
  CPU time spent in system time
• cpu_interrupt_time
  CPU time spent handling interrupts (hardware and software)
• cpu_exec_vm_time
  CPU time spent in virtual machine execution
• elapsed_time
  Time in microseconds used for this measurement

Notes
