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. License: GNU General Public License (GPL) Changes:
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.
