I am using perf. On Graviton, the event you want to look for is LLC-load-misses, which tracks last-level cache (LLC) misses (i.e., external memory accesses). The command "perf record -e LLC-load-misses -t $(pgrep valley-server)" will record the number of LLC misses per instruction during the execution of the valkey-server main thread. Please note that LLC-load-misses events are not collectable when running on instances that only use a subset of the processor's core. "perf list" provides the events that can be collected on your machine
