Q: “[Transaction Info] - Submitted: 15000 Succ: 268 Fail:14729 Unfinished:3”, timeout is too small, default value is used instead. Invoke chaincode failed, error: failed to get valid event notification.
A: The reason of high failures may be due to the configured transaction rate exceeding the processing capacity of fabric and caliper itself. You can check the cpu usage of peers or bench-clients (it should be printed after each test round) to see if it is too high. You can lower the tps value in 'config-fabric.json' and run the test again to find out the maximum performance your SUT can reach

Q: How to benchmark a multi-hosts fabric network?
A: Using caliper is completely independent of setting up the blockchain backend, the convenience ‘command.start’ script simplifies setting up things in development time, but it is optional, you can connect to an already running remote fabric network by setting the appropriate endpoints in the network config that is passed to caliper.

Q: When using the same setup (containers, genesis block,policies), the result of simple network and balance transfer network are different. Why? Not sure , but I have some thoughts:
A: please do the two step.
a. please check whether the configuration of peers and orderers in both networks are the same, such as loglevel, tls, etc.
b. Lower the sending rate. Now the sending rate is much higher than actual throughput, that may cause unsteady performance results.

Q: Invoke chaincode failed, error：failed to get valid event notification at channel. sendTransaction.then.then(/src/fabric/e2eUtils.js)
A: the machine cannot handle the > 100 TPS rates during the rounds when everything is running on the same host. Try lowering the TPS rates to 10 in config.json. in an environment with limited resources, the connections to the eventhubs might be abruptly closed, that is why you donnot get the notification.
