ndbinfo: The NDB Cluster Information Database 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 • thr_no • OS_user_time • OS_system_time • OS_idle_time • exec_time • sleep_time • spin_time • buffer_full_time • send_time • elapsed_time Elapsed time Thread buffer full time Thread send time Thread spin time Thread sleep time Thread execution time OS idle time OS user time OS system time Thread ID (specific to this node) ID of the node where the thread is running 23.5.14.20 The ndbinfo cpustat_20sec Table 4543 • node_id 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:
