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

buffer_full_time
