Very Simple Network Monitor is a bash shell script CGI that monitors a number of services on a network. It currently checks for node-up, TCP service up, and UDP service up. A service or system can be put in maintenance status to avoid repetitive alarms. It is easy to customize, trigger alarms by email, or whatever you like (depends on nmap for TCP/UDP service checks). Installation is also simple. It generates HTML with all statuses, and for all services just in one view.

Release Notes: A small bug was fixed in the poller.
Release Notes: No extra features were added. Only some bugs were fixed, making this the first "stable" release. A reporting bug was fixed. A bug in which alarm caused nmonitor to be locked was fixed. Some typos in the INSTALL document were corrected.
Release Notes: This is a complete rewrite. It is Web configurable, fully customizable, and has plugins for checks and alarms. Standard checks include ping scan, TCP scan, and UDP scan, and standard alarms include email and Web pages. Configuration, status, and logs are stored in MySQL. It is entirely written in PHP, except for the plugins, which are in bash. plugins can be any language, as long as the calling protocol is respected.
Release Notes: MySQL status logging and reporting was added for PHP/MySQL/Apache. This can generate uptime reports per service, such as failure reports, detailed service reports, and more.
Release Notes: Email notification support was added. The program now works as cronjob, so continuous monitoring is no longer necessary. The speed of the Web page generation process has been drastically increased by the use of a state database.
