LPAR CPU Sizing

Thank you so much for helping me with this. What I am trying to do is get relative Usage percentages in share lpar environment so that it is very convenient to immediately know what is the usage, are we within capacity etc.

Here is the formulat that I am using to calculate the Relative CPU usage:

Code:

$Total = $USR + $SYS;
        if ( $EC > 100 ) 
          {
          $RelativeCores = $PC;
          $UsedCores = ($Total / 100) * $RelativeCores;
          $RelativePercent = $UsedCores / $Entitlement * 100
        else
          {
          $RelativeCores = $Entitlement;
          $RelativePercent = $Total;
          $UsedCores = ($Total / 100) * $Entitlement;
          }

With the above formulas, I am calculating the Relative CPU usage in share lpar environment. So, If I wanted to calculate the threshold on relative percentage, what would be the formula.

Eventually, I would like to create a relative cpu percent chart, put a horizontal line for the threshold and looking at the chart, I would quickly know where am I at with the CPU. Does this make sense?

edit by bakunin: please use CODE-tags for that sort of text: programs, program-like structures, terminal data, etc... Thanks.

perlio::via::symlink

symlink(3pm)						User Contributed Perl Documentation					      symlink(3pm)

NAME

       PerlIO::via::symlink - PerlIO layers for create symlinks

SYNOPSIS

	open $fh, '>:via(symlink)', $fname;
	print $fh "link foobar";
	close $fh;

DESCRIPTION

       The PerlIO layer "symlink" allows you to create a symbolic link by writing to the file handle.

       You need to write C"link $name" to the file handle. If the format does not match, "close" will fail with EINVAL.
