CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. This was a weird problem to think about: Time itself had now become a resource and target of performance analysis. As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI.

Linux has been adding tracing technologies over the years: kprobes (kernel dynamic tracing), uprobes (user-level dynamic tracing), tracepoints (static tracing), and perf_events (profiling and hardware counters). My rock solid experience with Ubuntu is on an LTS release. ## Crash Dump Analysis It can be done.
