Recently, IRTF's Network Management Research Group (NMRG) has been collecting a large number of traffic traces of the Simple Network Management Protocol (SNMP). The main objective is to use these traces to investigate how SNMP is being actually employed, for example, by answering questions such as: which version of SNMP is more frequent, or is SNMP really relegated to support monitoring tasks and rarely used for device configuration? With a huge amount of traces, which is the case, the observation of the protocol's behavior tends to blur, but visualization techniques can help to understand the traffic patterns. In this presentation we will introduced an Web-based tool developed to manipulate SNMP traces and visualize them using three adapted techniques: topology maps, histograms, and information threes. The goal of the tool is expose the management traffic using visual representations that could enable the human observer to identify characteristics not easily detected by traditional analysis tools.
