Sorry, basically, I wanted to calculate uptime as a percentage
(preferably over the year), however, I then found the $uptime variable
only counted since the last reboot, therefore I wanted to show when the
server was last rebooted and also divide uptime by the server reboot
time. This is the code i was using, please note, i have added variables
into the 'start date' so I can set the reboot date manually. I wondered
if there was a way to do this manually.
<?php
$uptime = @exec('uptime');
preg_match("/averages?:
([0-9\.]+),[\s]+([0-9\.]+),[\s]+([0-9\.]+)/",$uptime,$avgs);
$uptime = explode(' up ', $uptime);
$uptime = explode(',', $uptime[1]);
$uptime = $uptime[0].', '.$uptime[1];
$sday = 12;
$smonth = 07;
$syear = 2005;
$start=mktime(0, 0, 0, $smonth, $sday, $syear, 0);
$end=mktime(0, 0, 0, date("m"), date("d"), date("Y"), 0);
$diff=$end-$start;
$days=$diff/86400;
$percentage= round(($uptime/$days) * 100, 2);
#$load=$avgs[1].",".$avgs[2].",".$avgs[3]."";
