Unable to use perf to find L3 Cache miss rate

I am trying to get the L3 cache miss rate when I try to use perf. The following is the command I run: perf stat -e instructions,LLC-load-misses,LLC-loads ./program Then I get the following output: 667,922,092,353 instructions LLC-load-misses LLC-loads 47.619915412 seconds time elapsed 42.245969000 seconds user 5.371741000 seconds sys I have already run the following command to install perf: apt-get install linux-tools-common linux-tools-generic linux-tools-uname -r The following are my system specs: OS: Ubuntu 22.04.1 \ Kernel: 5.15.0-58-generic \ CPU: AMD Ryzen 9 5900x It also does not work if I run as root
