Network sensors monitor all packets that flow through the switch and categorize the packets by application.
After you deploy a network sensor to the port mirror, SPAN, or network tap, the sensor monitors packets to and from the node, identifies the application or the URL, and analyzes the packets for QoE metrics, such as response time or traffic volume.
The network sensor must be installed on a Windows computer that is monitoring the switch's SPAN or mirror port.
Make sure you select the Windows machine that is monitoring the SPAN or mirror port of the switch.
When the sensors are successfully deployed, a message is displayed in Notifications.
Deploying the sensor and receiving the first set of data can take several minutes. When the deployment is finished, select the sensor on the Manage Quality of Experience (QoE) Packet Analysis Sensors page, click Edit Sensor, and verify the selected NIC.
After you deploy a network sensor, you can filter application traffic based on domain names instead of all http traffic.
QoE can automatically detect the first 50 applications, or you can add specific applications.
Discovered applications have the "No Risk" Risk Level and the "Both Business and Social" Productivity Rating associated with them. To modify the Risk Level and Productivity Rating, click QoE Settings > Manage (QoE) Applications, and edit the application.
Use the Global QoE Settings page to disable monitoring or discovery of multiple applications. Select the applications, and click Disable Monitoring or Disable Discovery.
Nodes are automatically detected and added by default. To specify which nodes and applications to monitor manually, see Monitor QoE applications and nodes.
