Network Meter 1.1.0.0: In case you work on a machine with more than one network adapter, it might be a good idea to know how much bandwidth is used up by each adapter. Network Meter is a network information tool that monitors any installed adapter and provides traffic details. Users are required to pick a network interface to monitor because Network Meter doesn’t automatically select the one currently in use. Once Network Meter starts collecting statistics, you can see the current and the total download and upload rates, along with a simple graph to track recent activity. Session totals are also available, and so is a network properties window that displays the maximum device speed, MTU size, MAC address and network type. www.softpedia.com
OpenNMS: A network management application written in Java. It claims to be the world’s first enterprise network management developed under an open source model. The project was registered on SourceForge on July 2000. Designed to scale to thousands of notes from one installation, OpenNMS can automatically discover network services and has an API for integration with bug tracking systems. While commercial development and support services are available through opennms.com, the project makes a point about not having a proprietary “enterprise” version.
