This shows you usage figures for the CPUs, memory, root disk drives, and data disk drives.

Use these figures to decide whether you need to change the configuration of your VM. See the sizing information in Appliance requirements.

CPU logical processor usage.

High CPU usage

High CPU usage is expected behavior.

This is because some cores are running the Data Plane Development Kit (DPDK) in poll mode to improve performance. See

For example, when Sophos NDR is running on a VM with 4 CPU cores, one core stays at 100% usage.

When Sophos NDR is running on a VM with 8 CPU cores, two cores stay at 100% usage.
