Benchmarking with Hyperledger caliper on multi host deployed Hyperledger fabric v1.4.1 network with raft consensus

My hyperledger fabric network is deployed on a private network on 4 servers. Each server has one peer and one orderer. The network is up and running and i want to do benchmarking with hyperledger caliper on the running network. TLS is enabled in the network, and i have given absolute path everywhere.

I changed the urls with the url of servers in both benchmark and network configuration file of caliper. I don't want to create any channel or enroll any admin or install chaincode because i've already done all of that steps. How does one do benchmarking from here ?

  1. My config.yaml file is as follows : 
---
test:
  name: drm
  description: Benchmark for DRM scenario
  clients:
    type: local
    number: 1
  rounds:
  - label: publish
    txNumber:
    - 10
    arguments:
      itemBytes: 2048000
    rateControl:
    - type: fixed-rate
      opts:
        tps: 1
    callback: benchmark/drm/publish.js
  - label: query
    txNumber:
    - 10
    rateControl:
    - type: fixed-rate
      opts:
        tps: 1
    callback: benchmark/drm/query.js
monitor:
  type: docker
  docker:
    name:

  }
}

Expected : Should just run benchmark without creating channel, installing chaincode and enrolling admin...

Actual Results : Stops at [create-channel.js] .

 error: [FabricCAClientService.js]: Failed to enroll admin, error:%o message=Enrollment failed with errors [[{"code":19,"message":"CA 'ca.org0.example.com' does not exist"}]], stack=Error: Enrollment failed with errors [[{"code":19,"message":"CA 'ca.org0.example.com' does not exist"}]]

But the network is just running fine!! Can anyone explain me, what am i doing wrong here ?

1) The error message indicates that the name you set for the CA in the config doesn't match the name of the Fabric-CA server. Note, that Fabric-CA servers have a FABRIC_CA_SERVER_CA_NAME setting, and it matters. The two names must match.

2) The released version of Caliper has better support for multi-orderer networks, provided by the new Fabric adapter. Also, an example is provided in the caliper-benchmarks repo.
