title: how to notify user when glassfish is down
body: <p>I am using <strong>Glassfish v3.0.1</strong> for my project. However, Glassfish seems to be down many times. Therefore, I want to develop a mechanism that notifies me whenever Glassfish is down. Is there any option in Glassfish? If not, how can I achieve this? Further, how can I understand why Glassfish goes down? I cannot find proper explanations in logs. </p>
