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.
