GNetWatch is an application that offers real-time graphical monitoring and analysis of network performance through SNMP and ICMP. To get an instant view of the network state, data are collected, stored, and displayed every few seconds. Two traffic generation modules are available. The former can flood UDP packets of any size (jumbo frames for instance) and tagged with any DiffServ/ToS flag for QoS and class of services testing. The latter can generate a huge quantity of parallel requests to any HTTP(s) server for Web application load testing. To automatically discover new hosts, GNetWatch can make use of Ethereal/WireShark and later invoke NMap to get information about the remote systems. Note that IPv6 and SNMPv3 are fully supported by GNetWatch.

Release Notes: Many more SNMP tables may be downloaded (like routing, ARP, interfaces, and MAC tables), and multiple graphs may now be displayed on the same statistics window.
Release Notes: This update lets the user add their own probes by means of generic actions that can spawn external processes or track the content of external files. Some standard generic actions are also provided: remote CPU load and remote free memory (using Windows Management Instrumentation for MS Windows targets and system tools for Unix/Linux targets). The documentation has been updated with these new features.
Release Notes: The GNetWatch documentation has been fully rewritten to describe every function available in the GNetWatch 3.0 release. It is now available in two formats: PDF and single-page HTML. The installation and configuration sections have been widely improved. The integration of an external database is now described. Moreover, a tutorial section has been added to explain how to achieve the main operations step-by-step. Finally, information about GNetWatch internals is provided.
Release Notes: This release comes with a complete rewrite of the internal data engine, now based on an Object-Relational mapping performed using hibernate. Configuration parameters, targets, and collected data are now persistent and stored in an SQL database. Users can thus browse previously collected data by dragging the mouse in the chart windows. For easy deployment, MS Windows and Linux bundles are shipped preconfigured with an embedded SQL engine: there is no need to configure any external database.
Release Notes: The documentation has been widely updated in the Documentation section of the site: you will now find a lot of information about GNetWatch concepts, supported operating systems, localization, installation of bundles, etc. A quick start guide has been added to help with running GNetWatch before reading the full documentation.
