public Interface Perfstat

extends Library
Imports
com.sun.jna.Library, .Native, .NativeLong, .Structure, .Structure.FieldOrder, .Union
The perfstat API uses the perfstat kernel extension to extract various AIX® performance metrics. System component information is also retrieved from the Object Data Manager (ODM) and returned with the performance metrics. The perfstat API is thread–safe, and does not require root authority.

Method Summary

Modifier and TypeMethod and Description
public int

Returns:

The return value is -1 in case of errors. Otherwise, the number of structures copied is returned.
perfstat_cpu(Perfstat.perfstat_id_t
Structure containing empty string when collecting all cpu stats, or null to count CPUs
name, Perfstat.perfstat_cpu_t[]
Populated with structures, or null to count CPUs
cpu, int
Should be set to sizeof(perfstat_cpu_t)
sizeof_struct, int
Set to 0 to count CPUs, set to number of cpus to return otherwise
desired_number)

Retrieves individual processor usage metrics

public int

Returns:

The return value is -1 in case of errors. Otherwise, the number of structures copied is returned. This is always 1.
