MySQL 8.0 Release Notes
MySQL 8.0 Source Code Documentation
The cpustat-1sec table provides raw,
per-thread CPU data obtained each second for each thread running
in the NDB kernel.
Like cpustat_50ms and
cpustat_20sec, this table
shows 20 measurement sets per thread, each referencing a period
of the named duration. Thus, cpsustat_1sec
provides 20 seconds of history.
The cpustat_1sec table contains the following
columns:
node_idID of the node where the thread is running
thr_noThread ID (specific to this node)
OS_user_timeOS user time
OS_system_timeOS system time
OS_idle_timeOS idle time
exec_timeThread execution time
sleep_timeThread sleep time
spin_timeThread spin time
send_timeThread send time
buffer_full_timeThread buffer full time
elapsed_timeElapsed time
