Monitor host resources (processor load, disk usage, etc)
Simple plug-in design allows you to easily develop your own service inspection
Parallel service check
Define the network host hierarchy using the "parent" host to detect and differentiate hosts
When a service or host problem occurs, it notifies you (via email, pager or user-defined method)
Define the event handler capability to proactively solve problems during service or host running
Log Files
Support for redundant host monitoring
Optional Web interface to view the current network status, notification and problem history, log files, and so on.
