Set the number of CPU cores and the amount of memory QoE can use

When a sensor is deployed, QoE automatically allocates one CPU core and 256 MB of memory to the sensor. After the sensor is installed, you can change the allocated CPU cores and memory.

For sensors, the memory usage scales with the traffic load. The more flows that are going on the line, the more memory you need.

Number of CPU Cores	Guidelines
1	Not Recommended
2	Suitable for 100 Mbps links
3 - 4	Gigabit links with low utilization
5 - 6	Gigabit links with medium utilization
7+	Gigabit links with high utilization

1. Click Settings > All Settings in the menu bar.
2. Click QoE Settings > Manage QoE Packet Analysis Sensors.
3. Select the sensor to edit.
4. Click Edit Sensor.

5. In the Memory field, select the number of GB you want to allocate to the sensor.

   If you allocate less than the recommended amount of memory, you may see reduced performance.

6. In the CPU Cores field, select the number of CPU cores you want to allocate to the sensor.

   If you allocate fewer than the recommended number of CPU cores, you may see reduced performance.

7. Click Save.
