For many of the kernel tracing tools, I'll add user stack traces as needed for the user context. TCP connections and latency _with_ the Java code paths responsible; ditto for disk I/O, memory growth, lock contention, etc. If you've ever had a network problem, a disk I/O problem, a memory problem, etc, BPF can give you new insights that are unavailable from user-space tooling.
