Network Packet Sensor

    Network Packet Sensor is an agent installation that operates as both NetFlow Generator and Deep Packet Inspection Engine. Network Packet Sensor can be used to monitor server and network traffic and conduct deep packet inspection. It reads, translates, and transmits the header information of the network packet to ManageEngine NetFlow Analyzer upon installation. It monitors the network response time and application response time, and conducts an analysis to find out whether the network or the application is causing issues. The following steps explain how to download and install the Network Packet Sensor agent.
