Cron Logger

With Cron Logger the wp-cron.php runs are logged. They are available in Tools -> Cron Logs.

Custom logs

If you have a cron run in your plugin that does not use the wp-cron.php, you can still use Cron Logger. Register your own Plugin with cron_logger_init action.

/**
 * @param CronLogger/Plugin $logger
 */
function my_plugin_init_logger($logger){
	// start a log session (call only once per session)
	$logger->log->start('Log my Plugin');
	
	// now you can add logs to the session
	$logger->log->addInfo("Now my Plugin starts doing this...");
	
	// you can log passed time in seconds too
	$duration = 3;
	$logger->log->addInfo("Now my Plugin has done that...", $duration);
}
add_action("cron_logger_init", "my_plugin_init_logger");

Custom log expiration time

function my_plugin_cron_logger_expire(int $days){
	return 60; // logs will expire and cleaned up after 60 days
}
add_filter("cron_logger_expire", "my_plugin_cron_logger_expire");
