ndbinfo: The NDB Cluster Information Database 23.5.14.18 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: ID of the node where the thread is running Thread ID (specific to this node) OS user time OS system time Thread execution time OS idle time Thread sleep time Thread spin time Thread send time Thread buffer full time Elapsed time The  cpustat-1sec  table provides raw, per-thread CPU data obtained each second for each thread running in the  NDB  kernel. 23.5.14.19 The ndbinfo cpustat_1sec Table 4542 • elapsed_time • buffer_full_time • send_time • spin_time • sleep_time • exec_time • OS_idle_time • OS_system_time • OS_user_time • thr_no • node_id
