I found the problem. But I dont know how to solve it

openat(AT_FDCWD, "/sys/bus/event_source/devices/uncore_cbo_0/type", O_RDONLY) = -1 ENOENT (No such file or directory)
futex(0x7fb255732210, FUTEX_WAKE_PRIVATE, 2147483647) = 0
write(2, "terminate called after throwing "..., 48terminate called after throwing an instance of ') = 48
write(2, "std::runtime_error", 18std::runtime_error)      = 18
write(2, "'\n", 2'
)                      = 2
write(2, "  what():  ", 11  what():  )             = 11
write(2, "open", 4open)                     = 4
write(2, "\n", 1
)                       = 1

I just found uncore_cbox_0 in /sys/bus/event_source/devices/

What CPU are you running on, and do your CPU support perf?
