calculating CPU Utilization on Windows and unix machine Can't Post
Dear All,

I am new to perl programming, i want to create the script for cpu utilization of local system.

I serached through the internet and found some useful information.

Copy pasting the scripts for the reference

use Win32::SystemInfo::CpuUsage;
my $intvl = 1000; # in milliseconds
my $usage = Win32::SystemInfo::CpuUsage::getCpuUsage($intvl);

my $i = 0;
while($i < 5){ #query 5 times
$i++;
$usage = Win32::SystemInfo::CpuUsage::getCpuUsage($intvl);
print "$i: cpu usage $usage\n";
}

while running this script I am getting below errors

C:\Perl\bin>perl CpuUsage1.pl
Can't locate Win32/API/Prototype.pm in @INC (@INC contains: C:/Perl/site/lib C:/
Perl/lib .) at CpuUsage1.pl line 3.
BEGIN failed--compilation aborted at CpuUsage1.pl line 3.

There is another script i found as below


use strict;
use Win32::API::Prototype;
ApiLink( 'kernel32', q[ BOOL GetSystemTimes( LPFILETIME lpIdleTime, LPFILETIME lpKernelTime, LPFILETIME lpUserTime ) ]) or die $^E; sub SystemTimes { my( $idleTicks, $kernelTicks, $userTicks ) =( chr( 0 ) x 8 ) x 3;
GetSystemTimes( $idleTicks, $kernelTicks, $userTicks ) or die $^E; return map{ my( $lo, $hi ) = unpack 'VV', $_;
( $hi * 2**32 + $lo ); } $idleTicks, $kernelTicks, $userTicks;}
use constant { IDLE=>0, KERNEL=>1, USER=>2 };$|=1; my @last = SystemTimes;
while( sleep 1 )
{ my @now = SystemTimes; my @deltas = map{ $now[ $_ ] - $last[ $_ ] } IDLE, KERNEL, USER; my $busy = $deltas[ KERNEL ] + $deltas[ USER ]; my $pcUsage = ( $busy - $deltas[ IDLE ] )* 100 /( $deltas[ IDLE ] || 100e5 );
printf "\rCPU usage(%%): %6.3f ", $pcUsage; @last = @now;}

for this i am getting below error

C:\Perl\bin>perl CpuUsage1.pl
Can't locate Win32/API/Prototype.pm in @INC (@INC contains: C:/Perl/site/lib C:/
Perl/lib .) at CpuUsage1.pl line 3.
BEGIN failed--compilation aborted at CpuUsage1.pl line 3.



Can some one help me to sort this out or of there is any easy to find out the cpuutilization please suggest.

Thanks

Amit

The error message is telling you that you need to install the Win32::API::Prototype module.

Re: [Amitk] calculating CPU Utilization on Windows and unix machine [In reply to] Can't Post
If you're using Activestate perl, you normally use the ppm utility to install modules (via its gui interface or command line interface).

example:
Quote
c:\>ppm install Win32::API::Prototype
Since Activestate doesn't have the module in its repository, you'll first need to add the bribes repository ppm before installing the module.


If you're using strawberry perl, then you normally use the cpan command to install modules.

example:
Quote
c:\>cpan Win32::API::Prototype

hi

Thanks for your help.

I downloaded just prototype.pm file from internet and that script worked.

just for info while seraching i even got one script for calculating cpu load but for this i installed sysinfo package and even that also worked out.

Thanks so much

hi All,

SAR is command very useful for getting CPU utilization.

I used the samd created the script with samples and intervals.

Hopefully this will be useful to all .

#!/usr/bin/perl
use FileHandle;
sub collect_sar
{
my($samples,$interval,$outf)=@_;
open(SARF,">$outf");
autoflush SARF;
@fargs=("/usr/sbin/sar",$interval,$samples);
open(SAR,"@fargs|");
autoflush SAR;
while(<SAR>) {
continue if ( /%user %nice %system/);
if ( /^\d\d:\d\d:\d\d\s+\d+\s+\d+\s+\d+\s+\d+/ ) {
my @values = split(' ', $_);
my $idle = $values[9];
if ( $idle < 80 ) {
print "Cpu Utilization is increasing Please do the needful";
} elsif ( $idle < 60 )
{


open (MYFILE, '>>data.txt');

print " Cpu Utilization Crossed 40%";

close (MYFILE);



}
undef (@values);
}
}
close(SAR);
close(SARF);
&collect_sar(15,4,"sar.out");



Thanks

Amit
