Editing Server Load "Triggers"

[Echo1972]

I'm trying to figure out how to edit the server load triggers in Vbulletin 3.6.3. I've got the server load bar hack installed and when my server load hits approx 65%, servertoobusy kicks in and displays the overloaded server msg allowing only registered users to use the site along with staff members. What I would like to do is have servertoobusy kick in at around 45%-50% of server load and I am not finding how to do this.

In global.php, i have this:

// start server too busy $servertoobusy = false; if ($vbulletin->options['loadlimit'] > 0 AND PHP_OS == 'Linux' AND @file_exists('/proc/loadavg') AND $filestuff = @file_get_contents('/proc/loadavg')) { $loadavg = explode(' ', $filestuff); if (trim($loadavg[0]) > $vbulletin->options['loadlimit']) { $servertoobusy = true;

I am guessing I have to edit the loadlimit but I am not finding this or vbulletin->options in the file manager. If someone could point me in the right direction, I'd sure appreciate it.
