21.5.14.13 The ndbinfo cpustat_1sec Table

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

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

    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
