Octavian,
I am not sure of another HPUX utility that calculates the
CPU utilization percentage on the fly like top does. Since
you are being tasked to do this, I am betting this is the
value they want you to use.
#!/usr/bin/perl -w
use strict;
unlink "/tmp/prochogs.$$" if (-e "/tmp/prochogs.$$");
system ("top -u -h -d1 -s1 -f /tmp/prochogs.$$");
open (TOP,"/tmp/prochogs.$$") or die "Unable to open top file - $!";
my %Proc;
my $FoundList;
while (<TOP>) {
if (/^CPU/) {
$FoundList = 1;
next;
}
next unless ($FoundList);
my @Values = split;
$Proc{$Values[2]} = \@Values;
}
foreach(keys %Proc) {
print "$_ : $Proc{$_}->[11]\n";
}
So why write the output to a file and read it back in instead
of creating a pipe? Well, when run interactively, top on HPUX
formats the output with a bunch of ANSI escape sequences that
is a pain to parse.
This should give you what you want and is easy to modify. You
want to make sure your temporary file makes sense on your system.
