* External command interface that allows on-the-fly modifications to be made to the monitoring and notification behavior through the use of event handlers, the web interface, and third-party applications

-Nagios has many features that NetSaint lacks but the most important one is that it allows you to configure it using template based configuration files, This simplifies the configuration hugely and reduces the chance of mistakes. Your config for a server goes from this
- host[
[gatekeeper]=Gatekeeper (Main Cloverly Server);10.230.1.1;;check-host-alive;5;60;24x7;1;1;1;
