## 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. 

## 23.5.14.19 The ndbinfo cpustat_1sec Table 

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 

The cpustat-1sec  table provides raw, per-thread CPU data obtained each second for each thread running in the NDB  kernel.
