System Statistics

Select System Stats to see system usage statistics.

You can see usage figures for the CPU cores, memory, data disk drives, and root drive.

Use these figures to decide whether you need to change the configuration of your VM. See Sizing the virtual appliance.

High CPU utilization

High CPU utilization 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% utilization.

This is what you'll see:

System statistics - 4 cores

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

Here's an example:

System statistics - 8 cores
