For a small traffic site like xoops-tips.com, the Who's Online block does not accurately update and show who are really online. It will keep showing users as being online long after they have logged off.


The Who's Online block uses a 'garbage collector' function to clear and update the block, based on a pre-set frequency. The default value is set to 10% and this is to reduce the number of queries to the database. This means 1 in 10 chances, the block will get updated when you click/refresh your pages.

For a busy site like xoops.org, the 10% frequency works just fine. For a small site, you will keep seeing people online even though they have logged off long time ago because the block has not got updated.

A minor tweak/modification will increase the frequency and more accurately show Who's Really Online.

locate


// set gc probabillity to 10% for now..
if (mt_rand(1, 100) < 11) {
$online_handler->gc(300);
}

change value 11
if (mt_rand(1, 100) < 11)

to a higher value like 70, 80 or 90 (the busier your site the lower the value, so you don't really burden your server)
if (mt_rand(1, 100) < 70)
