21.5.10.13 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 following table provides information about the columns in the cpustat_1sec table. For each column, the table shows the name, data type, and a brief description. Additional information can be found in the notes following the table.
