I am using Hyperledger Caliper to benchmark Fabric and I am facing the following errors regarding the caliper workers. I am currently using verion 0.4.0 of caliper

2020-11-07T13:06:23.286Z - error: [EventService]: send[peer0.org1.example.com] - #1 - no targets started - Error: Event service peer0.org1.example.com is currently listening

I dont understand these errors. Any hint for what might causing them?

Thank you

A few questions that might help us to help you:

  • What version of the Fabric SDK do you bind Caliper to?
  • Are you using a gateway based connection?
  • Do you have any peer logs available that might also be showing errors?

The SDK errors shown hint that the creation of an Event service failed, which occurs on initial connection to the Fabric network for manager and worker processes as they prepare to interact with the network described in the "network configuration file"

  • Thank you for your response. I have posted in the question above some lines that repeat in the container logs of peer0.org1.example.com. The SUT I bind is `fabric:2.1` . Also when running the `npx caliper launch manager` command I include the flags `--caliper-fabric-gateway-enabled --caliper-fabric-gateway-discovery` . The NodeJs version I use is 10.23.0 – Erodotos Demetriou Nov 10 '20 at 17:06
  • OK, two more questions then: - are you using the caliper image? - is the network local? (ie the gateway does not require an additional localhost mode flag) – nkl199 Nov 11 '20 at 15:38
  • the network is local and I am not using the caliper image on docker! I installed it locally using npm – Erodotos Demetriou Nov 11 '20 at 22:04
