A couple of the sawtooth network docker images (or docker files) are missing:
sawtooth-tp-python
sawtooth-tp-settings

See https://github.com/Huawei-OSG/caliper/blob/master/network/sawtooth/simplenetwork/sawtooth-default-validators-simple.yaml

I was able to get sawtooth up and running by substituting these for hyperledger docker hub equivalents. I can send a PR for that if y'all would like.

Hi,
I am using caliper to do a benchmark test for Hyperledger fabric ledger. I noticed few things in the caliper code:

1. CPU stats calculation for remote docker containers in monitor-docker.js file https://github.com/Huawei-OSG/caliper/blob/master/src/comm/monitor-docker.js#L84 does not take CPU's count as a multiplying factor. Is there any specific reason for it ? The result obtained is actually half of the one obtained with docker stats container_id command computed locally.

Dear Developers,

I am trying to separate the benchmark artifacts from the code-base of Caliper. The directory structure I am trying to build is the following:

.
├── benchmarks
│   └── simple
│       ├── config.json
│       ├── contract
│           └── simple
│               └── simpletest.go
│       ├── fabric.json
│       ├── main.js
│       ├── node_modules
│           ├── ...
│       ├── open.js
│       ├── package.json
│       └── query.js
├── caliper
│   ├── ...

The first steps I took was separating the *.json and *.js files of the simple benchmark (so the contract and network paths remained the same). I performed the following in my new benchmarks/simple folder:

1. npm init && npm install commander fs-extra --save to run main.js
2. Changing the path of the network config file and callbacks in config.json to "config": "../benchmarks/simple/fabric.json" and "callback" : "../benchmarks/simple/open.js" since these should be relative to the Caliper root directory.
3. Changing the Caliper root path in main.js on line 43 to var absCaliperDir = path.join(__dirname, '../../caliper');

So far so good, I could install & instantiate the chaincode from its original caliper/src/contract/fabric/simple directory.

After this, I relocated the chaincode to my benchmarks/simple/contract/simple directory and changed the chaincode path in fabric.json to the following:
"chaincodes": [{"id": "simple", "path": "../../benchmarks/simple/contract/simple", "language":"golang", "version": "v0", "channel": "mychannel"}],
Based on the original path, I thought this should be relative to the caliper/src folder.

But running the benchmark gives the following error:

# Instantiate chaincode......
info: [EventHub.js]: _connect - options {"grpc.ssl_target_name_override":"peer0.org1.example.com","grpc.default_authority":"peer0.org1.example.com"}
error: [client-utils.js]: sendPeersProposal - Promise is rejected: Error: 2 UNKNOWN: Error starting container: Failed to generate platform-specific docker build: Error returned from build: 1 "can't load package: package ../../benchmarks/simple/contract/simple: open /benchmarks/simple/contract/simple: no such file or directory
can't load package: package ../../benchmarks/simple/contract/simple: open /benchmarks/simple/contract/simple: no such file or directory
"

    at /home/klenik/Projects/caliper/node_modules/grpc/src/client.js:573:15

I am lost at this point, since I do not know where this path is being rejected. On the client (SDK) side or the Fabric (peer) side? Did I miss something? How can I deploy chaincodes from outside your contract/fabric directory?

Thanks for the help!

Hey! I've tried to check fabric benchmarks but something went wrong

npm install && npm install fabric{,-ca}-client

how and which files do i need to edit to run the benchmark test for hyperledger/fabric-samples/first-network can you please update?

i have edited caliper/benchmark/simple/config.json like below,

"command" : {
"start": "command to start the first-network test",
"end": "command to stop"
},

and when i run the test, i got error as below
