CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI. Note that Ubuntu also has a frame to show entry into vDSO (virtual dynamic shared object). But I'm not completely sure.
