runtimefolder/package of the chain -

with-tracing = ["frame-executive/with-tracing", "sp-io/with-tracing"]under[features]to theruntimepackages'Cargo.toml -
compile the runtime with
cargo build --release --features with-tracing -
Tracing-enabled WASM runtime should be found in
./target/release/wbuild/{{chain}}-runtimeand be called something like{{your_chain}}_runtime.compact.wasm. This can be renamed/modified however you like, as long as it retains the.wasmextension. -
run it with overrides by placing this folder with all your other runtimes, and passing the path of this folder to your chain.
./target/release/polkadot --wasm-runtime-overrides /home/user/my-custom-wasm-runtimes
