Thank you for the reply. Unfortunately, py-spy fails to run and outputs the error
$ ./py-spy top --pid 67
thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: ParseIntError { kind: PosOverflow }', /root/.cargo/registry/src/github.com-1ecc6299db9ec823/proc-maps-0.2.1/src/linux_maps.rs:81:65

I followed the guide found here, the second last post contains another person running into the same problem a while ago, but no solution unfortunately.
