To find the system load use the following perl snippet : System load of last one minute : my $system_load = exec('<a class="zem_slink" title="Uptime" rel="wikipedia" href="http://en.wikipedia.org/wiki/Uptime">uptime</a> | awk -F "load average: " \'{ print $2 }\' | cut -d, -f1'); my $system_load = qx('uptime | awk -F "load average: " \'{ print $2 }\' | cut -d, -f1'); System load of last 5 minutes : my $system_load = exec('uptime | awk -F "load average: " \'{ print $2 }\' | cut -d, -f2'); my $system_load = qx('uptime | awk -F "load average: " \'{ print $2 }\' | cut -d, -f2'); System load of last 15 minutes : my $system_load = exec('uptime | awk -F "load average: " \'{ print $2 }\' | cut -d, -f3'); my $system_load = qx('uptime | awk -F "load average: " \'{ print $2 }\' | cut -d, -f3');
