MySQL 8.0 Reference Manual Including MySQL NDB Cluster 8.0
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
