tokio-console support

tokio-console is a diagnostics and debugging tool for asynchronous Rust programs. This tool can be useful to lint runtime behavior, collect diagnostic data from processes, and debugging performance issues. "it's like top(1) for tasks!"

Setup

Support for tokio-console is not enabled by default for zebrad. To activate this feature, run:

$ RUSTFLAGS="--cfg tokio_unstable" cargo build --no-default-features --features="tokio-console" --bin zebrad

Install tokio-console.

Then start zebrad however you wish.

When zebrad is running, run:

$ tokio-console

The default options are used, so tokio-console should connect to the running zebrad without other configuration.
