#### 23.6.14.21 The ndbinfo cpustat\_20sec Table

[]()

 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`](mysql-cluster-ndbinfo-cpustat-50ms.html) and [`cpustat_1sec`](mysql-cluster-ndbinfo-cpustat-1sec.html), 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:

* `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
