What are some potential pitfalls to be aware of when using a Cronjob in PHP for monitoring tasks?

One potential pitfall when using a Cronjob in PHP for monitoring tasks is not properly handling errors or exceptions that may occur during the execution of the task. To avoid this, it is important to implement error handling mechanisms within the PHP script that is being executed by the Cronjob. This can include using try-catch blocks to catch and handle any exceptions, logging errors to a file, or sending error notifications to the appropriate parties. 

<?php

try {
    // Code for monitoring task goes here
} catch (Exception $e) {
    // Log the error to a file
    file_put_contents('error.log', $e->getMessage(), FILE_APPEND);
    
    // Send an email notification to the appropriate parties
    $to = 'admin@example.com';
    $subject = 'Error in Cronjob monitoring task';
    $message = 'An error occurred: ' . $e->getMessage();
    mail($to, $subject, $message);
}

?>
