Since the cronjobs runs (after defined intervals) you can register task in your component. Example
~~~
<?php
function cron_init(){
ossn_register_callback('cron', "loaded", 'cron');
}
function cron($cb, $type, $args){
echo ossn_dump($args);
//set a custom timestamp for your own component
//as you may not wanted to run task during the interval defined.
ossn_cron_set_handler_last_activity('videos');

ossn_cli_output("Process started", 'success');
ossn_cli_output("Process issue", 'warning');
/// your stuff here
ossn_cli_output('Process error', "error");
}
ossn_register_callback('ossn', 'init', 'cron_init');
~~~
