Probe is a web GUI application with for Hyperledger Fabric mantianer, user, research to find the best block config logic for specific chaincode and fabric network.
- Probe provides loop test control for given block parameter arrays.
- Probe provides sample chaincode for some test cases.
- Probe provides TPS result review as below:
for each graph from output, label as below
| x | y | z |
|---|---|---|
| BatchTimeout | MaxMessageCount | tps |
| BatchTimeout | AbsoluteMaxBytes | tps |
| BatchTimeout | PreferredMaxBytes | tps |
| MaxMessageCount | AbsoluteMaxBytes | tps |
| MaxMessageCount | PreferredMaxBytes | tps |
| AbsoluteMaxBytes | PreferredMaxBytes | tps |
As discussed with TWGC performance work group, we found out that different block parameters, networks, chaincode language and chaincode logic having influence final TPS. To answer, the best parameter for specific fabric network and fabric chaincode, I create this project.
You are able to have better understanding with performance for specific chaincode logic by:
- Perpare probe for your test env.
- Start probe with parameters.
- Once ompleted, you will get the TPS rates with block parameters in GUI as above.
You are able to know better with how your changes impacts Fabric TPS in over all view.
- Completed your changes, and dokerize your Fabric.
- Start probe with parameters.
- Once completed, you will well known how your changes impacts Fabric TPS.
- Real time time monitor, for real time tps monitor, pls use prometheus.
- Auto test framework for Fabric performance, as in probe, we will invoke as byfn or minifab for your network up/down/cleanup.
- Performance test tool for Fabric, for this we using tape.
- GUI for tape, tape focus on once off time performance testing.
- install this project
npm install - install fabric sample
curl -vsS https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh | bash - get tape
docker pull guoger/tape - apply the bridge file to adjust block parameters for test network
cp sample/prepareConfig.sh fabric-samples/test-network - npm start
- access localhost:3000, submit form with placeholder
- access localhost:3000/result/BatchTimeout
- access localhost:3000/result/MaxMessageCount
- access localhost:3000/result/AbsoluteMaxBytes
- access localhost:3000/result/PreferredMaxBytes
