AliveMon 2.0
Description:
AliveMon is a network monitor that lets you know when servers or routers fail. Configurable alarms enable you to quickly solve problems before they turn into real headache. You can even automatically take corrective actions by auto-starting programs. Application-specific probes let you check the actual status of your application (like web or game servers). Many other tools just do a ping, which only checks the system itself, not the application.
