SNMP and Beyond: A Survey of Network Performance Monitoring Tools

Paul Moceri,

The growing dependence on networks for everyday tasks has created the demand for high performance, reliable networks. Part of achieving the goal of high performance is active monitoring of networks to help in the identification and prevention of network errors. Many tools have emerged to aid in performance monitoring of networks. The most common class of tools is based on the Simple Network Management Protocol (SNMP), a protocol for sending and transmitting network performance information on IP networks. Other types of network performance monitoring tools include packet sniffers, flow monitors and application monitors. Examples of the various monitoring tools are SolarWind's Orion SNMP monitoring platform, Ethereal packet capture tool, Webmetrics' GlobalWatch and Cisco's NetFlow flow monitoring tools.
