Hi @Maple1401 and @1473371932 , thank you for your input.

It was probably caused because the older Kernel didn't have BTF enabled and a later upgrade included BTF.

We will anyway review the current functions and adjust the requirements to it.

struct {
    __uint(type, BPF_MAP_TYPE_RINGBUF);
    __uint(max_entries, 1 << 24);
} events SEC(".maps");

Because ringbuf requires kernel version >= 5.8

We actually upgraded the requirements to Kernel 5.8 in the documentation: https://grafana.com/docs/beyla/latest/#requirements

Closing this task. Thank you for your input!
