[0x3N3jVhPUV]

Which operating system are you using?

Ubuntu 20.04 lts

Please provide some context for your error. For example, when did the error occur? What were you trying to achieve, and how?

Hello, I am new to Hyperledger Caliper and I would like to benchmark my Besu (IBFT2) private network by adding the URL (websocket) of its RPC endpoint, in the networkconfig.json located in networks/ethereum/1node-clique.

What was the observed incorrect behavior?

When I am trying to launch caliper, I’m gettting an error message which indicates that Caliper cannot communicate with my private network. Logs seem to indicate that Caliper cannot communicate with my private network and I don't understand why since my private network is running.

Please provide the error logs and their surroundings.

Here are the logs: 

2022.02.25-00:22:34.962 error [caliper] [caliper-engine]        Error while performing "init" step: Error: connection not open

Please provide your network configuration file content, if possible.

Here is my networkconfig.json:

                }
            }
        }
    }
}

Please provide any additional information you deem relevant to the error.

Here are the commands that I’m using:

npm init -y
npm install --only=prod \ @hyperledger/caliper-cli@0.4.0
npx caliper launch manager \
    --caliper-bind-sut besu:latest \
    --caliper-workspace . \
    --caliper-benchconfig benchmarks/scenario/simple/config.yaml \
    --caliper-networkconfig networks/ethereum/1node-clique/networkconfig.json

Hello @davidkel,

Thank you very much for your answer!

It working fine with "ws://localhost:8546" !

However, when I reproduce the same steps, in order to benchmark my Besu private network by adding the URL ( "ws://xx.xxx.xxx.xxx:8546") of its RPC endpoint, I get an error code 5. I failed to install smart contract but I don't understand why since the contractDeployerAddress and the contractDeployerAddressPrivateKey that I'm using are coming from the genesis.json of my private network.

Last, I'd like to mention that I didn't merge all commands into a single one.

I wonder what I did wrong.

Here are the logs I get, after running the command to benchmark the simple scenario:
