Crash at start

[nateless]

Hey,

Tried to run it, and it crashes:

2023-05-04 11:39:28,543 INFO [main] Starting bitcoind-observer using /usr/local/bin/bitcoind ...
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: EnableUSDTProbe', src/main.rs:43:10

Am I doing something wrong?

fwiw: this project is quite experimental and I don't recommend running it if you don't know what you're doing.

That said, what Bitcoin Core version do you run? Are the tracepoints compiled in?

We are using 24.0.1, I've double checked right now. Even though we provided --enable-usdt its not enabled and built without it, it seems..

Options used to compile and link:
  ...
  use asm         = yes
  USDT tracing    = no
  ...

Not sure why, and I can't find any errors or missing libraries during configuration process.

See the "User-Space, Statically Defined Tracing (USDT) dependencies" part in Linux Distribution Specific Build Instructions. You're probably missing the systemtap headers.

Also see https://github.com/bitcoin/bitcoin/blob/master/doc/tracing.md#listing-available-tracepoints for methods to check if your binary contains tracepoints.
