I'm trying to test the performance of my own fabric network build with caliper, but I'm running into some trouble.

[michaeljimson]

Which Caliper version are you using?

V0.4.2

Which Node.JS version are you using?

v16.15.0

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?

I want to use caliper to test the performance of the fabric network I built, but I'm having some trouble. When testing the creation of transactions with caliper, some errors are often reported randomly.

What was the observed incorrect behavior?

SET function always has unsuccess
caliper.log

Please provide the error logs and their surroundings.

thanks a lot

I found problem. My chaincode using golang. I used a function to quire time like time.Now().Unix()，So the time-out make the Peer endorsements do not match. I use outside timestamp function in javascript to take place chaincode. It works.

[davidkel]

Firstly, I would recommend not using caliper 0.4.2 and use caliper 0.5.0 instead.
Secondly, caliper is outputting the reason for the failures

Failed to perform submit transaction [CreateRequest] using arguments [The 2 Message_13,444444444444,152601199604262615,123123123126,123123123135,152602200211117775],  with error: Error: No valid responses from any peers. Errors:
    peer=undefined, status=grpc, message=Peer endorsements do not match

Your endorsements received from 2 or more peers don't match. That means your chaincode is non-deterministic and so you have a problem with your chaincode implementation. Please search google and refer to the hyperledger fabric documentation about chaincode and the fact it must be deterministic. Examples of a chaincode that isn't deterministic would be

1. The chaincode generates a date object
2. The chaincode generates a random number

So this isn't an issue with caliper or fabric but how your chaincode is implemented

Thank you, Its my chaincode problem.not caliper. And again, thank you for your reply!
