ntopmg is a network probe that shows network usage in a way similar to what top does for processes. It acts as a Web server, creating an HTML dump of the network status. It sports a flow collector, an HTTP-based client interface for creating ntop-centric monitoring applications, and RRD for persistently storing traffic statistics. Its C++ core can be scripted in Lua, for changing the appearance and extending functionality.
OpenNMS is the first enterprise-grade network management platform developed using the open source model. The three main functional areas of OpenNMS are service polling, which monitors services on the network and reports on their "service level"; data collection from the remote systems via SNMP in order to measure the performance of the network; and a system for event management and notifications.
CD-R/W discs can be written with a technique called packet or incremental writing. This allows transparent and buffer-underrun-free recording for CD recorders that support this method. No more mastering of .iso images; just mount your CD-ROM read/write and copy files directly to it.
PagePoker is a Perl package that defines a browser agent with many powerful features for monitoring and testing Web sites, including elaborate failure handling that can send email and trigger SNMP traps. It comes with three scripts that implement it for different uses: poke.pl, for single agents; pokes.pl, for many parallel agents, and pokehard.pl, for loadtesting and benchmarking.
Paralogger is a script to "tail" the system logs in borderless transparent Eterm(s). Its purpose is to make setting up a "root tail" an easy set and forget. Paralogger makes the placement of the terminals (geometry) more friendly for the user by detecting the screen resolution and calculating the geometry of the terminals automatically. It can also load or save a configuration file.
