Attention! NS is a fault-tolerant software system. Attention! NS heartbeat monitoring provides you with assurance that Network Inspector itself is up and running 24x7. Should someone pull the plug on any system running a Network Inspector agent, Attention! NS will detect the outage within seconds, and begin the notification process.

You can also purchase a dual-Server Attention! NS configuration, providing seamless failover to a backup Attention! NS Server should the primary go down. Finally, the integrated Attention! NS Watchdog will notify you if your paging company stops offering service.
