  • What command are you using to start your chain?

I'm not sure if sc_cli provides these. AFAIK it didn't.


But here is a general solution.

Check this https://github.com/darwinia-network/darwinia/blob/12f3123d8c4d6fb8896d3f42dadb7b99a168fde1/cli/src/command.rs#L117-L122.

You could put any log in your startup function.

Example:

https://github.com/zsiciarz/rust-cpuid

match cpuid::identify() {
    Ok(info) => {
        log::info!("Found: {} CPU, model: {}", info.vendor, info.codename);
        log::info!("The full brand string is: {}", info.brand);
        log::info!("Hardware AES support: {}", if info.has_feature(cpuid::CpuFeature::AES) { "yes" } else { "no" });
    },
    Err(err) => log::info!("cpuid error: {}", err),
};
match cpuid::clock_frequency() {
    Some(frequency) => log::info!("CPU speed: {} MHz", frequency),
    None => log::info!("Couldn't get CPU speed."),
};

Now, I think the question duplicates with Node startup message missing after upgrade to Polkadot v0.9.23.

To make the "startup messages" show again, I had to fix the dependency of

tracing-core

cargo update -p tracing-core --precise 0.1.28
