21.6.15.12 The ndbinfo cpustat_50ms Table

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

Thread send time
buffer_full_time

Thread buffer full time
elapsed_time

Elapsed time

Notes

This table was added in NDB 7.5.2.
