With the difficulty of network traffic monitoring, this paper builds an MRTG traffic monitoring system. The long-distance network traffic flow monitoring parameters are set up according to Web services to enable them to monitor multiple devices in the cluster. Reliable data for graphical network traffic and equipment performance are released through Apache. MRTG’s defects in practical applications are studied. Reasonable and feasible improvement on the strategy is made, so that network managers can remotely monitor network traffic load and its performance. In this way, can they determine the possible causes of problems in network or equipment, so as to find the problem out and address them in a short time.
