MySQL 9.0 Reference Manual Including MySQL NDB Cluster 9.0
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_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

spin_time

send_time

buffer_full_time
