MySQL 5.7 Reference Manual Including MySQL NDB Cluster 7.5 and NDB Cluster 7.6
        The cpustat_50ms table provides raw,
        per-thread CPU data obtained each 50 milliseconds for each
        thread running in the NDB kernel.
      
        Like cpustat_1sec and
        cpustat_20sec, this table
        shows 20 measurement sets per thread, each referencing a period
        of the named duration. Thus, cpsustat_50ms
        provides 1 second of history.
      
        The cpustat_50ms table contains the following
        columns:
      
            node_id
          
ID of the node where the thread is running
            thr_no
          
Thread ID (specific to this node)
            OS_user_time

            OS_idle_time
          
OS idle time
            exec_time
          
Thread execution time
            sleep_time
          
Thread sleep time
            spin_time
          
Thread spin time
            send_time
