22.5.10.13 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.
