MySQL 8.0 Reference Manual Including MySQL NDB Cluster 8.0
The cpustat_20sec table provides raw,
per-thread CPU data obtained each 20 seconds, for each thread
running in the NDB kernel.
Like cpustat_50ms and
cpustat_1sec, this table shows
20 measurement sets per thread, each referencing a period of the
named duration. Thus, cpsustat_20sec provides
400 seconds of history.
The cpustat_20sec 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

sleep_time

send_time
