AIX::Perfstat
Perl wrapper for C<perfstat> functions.

AIX::Perfstat - Perl wrapper for C<perfstat> functions.


NAME

AIX::Perfstat - Perl wrapper for perfstat() functions.


SYNOPSIS

use AIX::Perfstat;

$cput = AIX::Perfstat::cpu_total();

$diskt = AIX::Perfstat::disk_total();

$netift = AIX::Perfstat::netinterface_total();

$memoryt = AIX::Perfstat::memory_total();

$num_cpus = AIX::Perfstat::cpu_count();

$num_disks = AIX::Perfstat::disk_count();

$num_netifs = AIX::Perfstat::netinterface_count();

$cpu_data = AIX::Perfstat::cpu(desired_number = 1, name = ``'');

$disk_data = AIX::Perfstat::disk(desired_number = 1, name = ``'');

$netif_data = AIX::Perfstat::netinterface(desired_number = 1, name = ``'');


DESCRIPTION

This Perl module lets you call all of the perfstat functions defined on AIX 5.1 and returns system data in Perl data structures.

The AIX::Perfstat::cpu_total, AIX::Perfstat::disk_total, AIX::Perfstat::netinterface_total, and AIX::Perfstat::memory_total functions each return a hashref containing all of the respective C structures.

The AIX::Perfstat::cpu_count, AIX::Perfstat::disk_count, and AIX::Perfstat::netinterface_count functions each return a count of how many structures are available from the AIX::Perfstat::cpu, AIX::Perfstat::disk, and AIX::Perfstat::netinterface functions respectively.

The AIX::Perfstat::cpu, AIX::Perfstat::disk, and AIX::Perfstat::netinterface functions each take up to two arguments and return a reference to an array of hashes. The arguments specify the number of records to return, and the name of the record to start with. These arguments are equivalent to the desired_number and name parameters to the perfstat functions. Only valid data is returned (Example: If you call AIX::Perfstat::netinterface(5) on a machine with only 2 network interfaces, the returned array will only contain two entries.) When these functions are called with a variable for the name parameter the variable will be modified in place to contain the name of the next available record, or ``'' if no more records are available.




=head2 EXPORT
