nPULSE is a web-based network monitoring package for Unix-like operating systems. It can quickly monitor tens, hundreds, even thousands of sites/device s at a time on multiple ports. nPULSE is written in Perl, uses nmap as its core scanning engine, and comes with its own mini web server for extra security.
