While trying to run benchmark with the following command, I am getting errors:

target/debug/imbue-collator benchmark --chain=pukimak.json --steps=100 --repeat=200 --pallet=proposals --extrinsic=* --execution=wasm --wasm-execution=compiled --heap-pages=4096 --output=example_weights.rs --template=./scripts/frame-weight-template.hbs


Error: Input("Error getting benchmark list: Other: Exported method Benchmark_benchmark_metadata is not found")

Used local chain spec via this command:

./target/debug/imbue-collator build-spec --chain imbue-dev --raw --disable-default-bootnode > pukimak.json

Update: Able to run benchmark help command using the collator on CLI:

imbue-collator 2.0.0-c68dc56-x86_64-linux-gnu
imbue <https://github.com/ImbueNetwork>
imbue testnet

The command-line arguments provided first will be passed to the parachain node, while the arguments
provided after -- will be passed to the relaychain node.

imbue-collator [parachain-args] -- [relaychain-args]

    imbue-collator [OPTIONS] [-- <RELAYCHAIN_ARGS>...]
    imbue-collator <SUBCOMMAND>

            Relaychain arguments

            Shortcut for `--name Alice --validator` with session keys for `Alice` added to keystore```

    How did you create pukimak.json? Probably you need to update this to the latest version of Substrate.

  • Generated the chain spec using the imbue collator with this command: Used local chain spec via this command: ./target/debug/imbue-collator build-spec --chain imbue-dev --raw --disable-default-bootnode > pukimak.json

    You need to build the chain with the --features=runtime-benchmarks flag

  • @ShawnTabrizi, I am trying what you suggested to better understand the chain spec dependency. ./target/debug/imbue-collator build-spec --chain imbue-dev --raw --disable-default-bootnode --features=runtime-benchmarks > pukimak.json, it errors out with the following: error: Found argument '--features' which wasn't expected, or isn't valid in this context If you tried to supply `--features` as a value rather than a flag, use `-- --features` USAGE: imbue-collator build-spec --chain <CHAIN_SPEC> For more information try --help

    Features should be before build-spec

try add your proposal pallet into benchmark metadata like this

Code change based on the input provided above:

    impl frame_benchmarking::Benchmark<Block> for Runtime {
        fn benchmark_metadata(extra: bool) -> (
        ) {
            use frame_benchmarking::{baseline, Benchmarking, BenchmarkList};
            use frame_support::traits::StorageInfoTrait;
            use frame_system_benchmarking::Pallet as SystemBench;
            use baseline::Pallet as BaselineBench;

            let mut list = Vec::<BenchmarkList>::new();
            list_benchmarks!(list, extra);

            let storage_info = AllPalletsWithSystem::storage_info();

            return (list, storage_info)

        fn dispatch_benchmark(
            config: frame_benchmarking::BenchmarkConfig
        ) -> Result<Vec<frame_benchmarking::BenchmarkBatch>, sp_runtime::RuntimeString> {
            use frame_benchmarking::{baseline, Benchmarking, BenchmarkBatch, TrackedStorageKey};

            use frame_system_benchmarking::Pallet as SystemBench;
            use baseline::Pallet as BaselineBench;

            impl frame_system_benchmarking::Config for Runtime {}
            impl baseline::Config for Runtime {}

            let whitelist: Vec<TrackedStorageKey> = vec![
                // Block Number
                // Total Issuance
                // Execution Phase
                // Event Count
                // System Events

            let mut batches = Vec::<BenchmarkBatch>::new();
            let params = (&config, &whitelist);
            add_benchmarks!(params, batches);

  • This worked. Thank you so much !!! Benchmark code reference: github.com/ImbueNetwork/imbue/commit/… File updated: runtime/development/src/lib.rs
