hello friends 

i have created an event in

1-   local/navitus/classes/event/bbb_viewed.php folder directory

namespace local_navitus\event;

class bbb_viewed extends \core\event\base {

    public static function get_name() {
        return "bbb_viewed";
    }


    public function get_description() {
        return "bbb_viewed";
    }


    protected function get_legacy_logdata() {
        return null;
    }

    /**
     * Init method.
     *
     * @return void
     */

    protected function validate_data() {
        parent::validate_data();

        /*if (!isset($this->relateduserid)) {
            throw new \coding_exception('The \'relateduserid\' must be set.');
        }
        if (!isset($this->other['subject'])) {
            throw new \coding_exception('The \'subject\' value must be set in other.');
        }
        if (!isset($this->other['message'])) {
            throw new \coding_exception('The \'message\' value must be set in other.');
        }
        if (!isset($this->other['errorinfo'])) {
            throw new \coding_exception('The \'errorinfo\' value must be set in other.');
        }*/
    }

    protected function init() {
        //$this->context = \context_system::instance();
        $this->data['crud'] = 'c';
        $this->data['edulevel'] = self::LEVEL_OTHER;
    }

<?php

defined('MOODLE_INTERNAL') || die();

$handlers = array(

);

$observers  = array(

    array(
        'eventname'   => '\local_navitus\event\bbb_viewed',
        'callback'    => '\local_bigbluebutton\bigbluebutton_observer::bbb_viewed_review',
        'priority'    => 200,
        'internal'    => 0,
    ),

);

3- place observer.php code in  local/bigbluebutton/classes/observer.php

<?php

namespace local_bigbluebutton;

defined('MOODLE_INTERNAL') || die();

//namespace mod_bigbluebuttonbn;

class bigbluebutton_observer
{

    public static function bbb_viewed_review(\local_navitus\event\bbb_viewed $event) {
        global $DB, $CFG, $USER;
        ob_start();
        var_export($event);
        $contents = ob_get_contents();
        ob_end_clean();
        error_log($contents);

        error_log("Bigbluebiutton Event Fired : ");

        return true;
    }


}

$context = context_course::instance($bbbsession['course']->id);

$data= array(
    'userid'=>$bbbsession['userID'],
    'starttime'=>time(),
    'endtime'=>'',
    'courseid'=>$bbbsession['course']->id,
    'cmid'=>$bbbsession['cm']->id,
    'status'=>'Attainding',
    'module'=>'VirtualClassroom'
);

$param=array(
    'context'=>$context,
    //'objectid' => $bbbsession['course']->id,
    'other'=>$data
);

$event=\local_navitus\event\bbb_viewed::create($param);

$event->trigger();

THE OUTPUT IS:

Can not execute event observer '\local_bigbluebutton\bigbluebutton_observer::bbb_viewed_review'
