Packet Analysis Sensor Agents
The software that provides a communication channel between your SolarWinds server and the monitored object to which you have deployed your Packet analysis Sensor is referred to as the agent. Agents are used to provide packet-level traffic information about key devices and applications that you specify. The agent runs as a service on Windows 2008, Windows 2008 R2, and Windows 2012, and it has a relatively small footprint (under 100MB installed).
