Message: [QUOTE="inetquestion, post: 4827727"] I can't seem to get rid of the error message if sar doesn't exist in the path. The redirection of stderr from within the backticks isn't working via perl. Is there another way to allieviate these errors from showing up in the console? Any suggestions on how to get cpuidle which will work on unix or windows? $CpuAvg=`sar -u 15 2>/dev/null | tail -1 | awk '{print \$5}'`; if ( $CpuAvg=~/[0-9]*/ ) { $CpuAvg=`vmstat 15 2 | tail -1 | awk '{print \$22}'`; } chomp($CpuAvg); -Inet [/QUOTE]
