Future items
  • PTE needs to supports any number of organizations in a channel. PTE supports two organizations per channel now (FAB-3809).
  • PTE can only send transactions to the anchor peer of an organization. It will need to be able to send transactions to any peer.
  • Endorsement policy is not supported yet.
  • Replace git clone https://github.com/hyperledger/fabric-sdk-node.git with fabric-client and fabric-ca-client.
  • Post-alpha2, remove v1performance info.

Prerequisites

To build and test the following prerequisites must be installed first:

  • node and npm lts/boron release (v6.10.x and v3.10.x)
    • node v7 is not currently supported
  • gulp command
    • npm install -g gulp
  • go (v1.7 or later)
  • others:
    • in Ubuntu: apt install -y build-essential python libltdl-dev
    • or refer to your distribution's repository

If planning to run your Fabric network locally, you'll need docker and a bit more. See Hyperledger Fabric - Getting Started for details.

Setup

  1. Download fabric sources and checkout appropriate commit levels (v1.0.0-alpha2 shown here):

    • go get -d github.com/hyperledger/fabric
    • cd $GOPATH/src/github.com/hyperledger/fabric/
    • git checkout v1.0.0-alpha2
    • Optional: make docker
    • go get -d github.com/hyperledger/fabric-ca
    • cd $GOPATH/src/github.com/hyperledger/fabric-ca/
    • git checkout v1.0.0-alpha2
    • Optional: make docker
    • go get -d github.com/hyperledger/fabric-sdk-node
    • cd $GOPATH/src/github.com/hyperledger/fabric-sdk-node
    • git checkout v1.0.0-alpha2

    If make docker is skipped, the assumption is that the user will either acquire docker images from another source, or PTE will run against a remote Fabric network. See Creating a local Fabric network for additional information on this.

  2. Install node packages and build the ca libraries:

    • npm install
      • you should be able to safely ignore any warnings
    • gulp ca
  3. Clone PTE Note: This will not be necessary in future releases (post-alpha2) as PTE has been merged into Fabric.

    • If testing v1-alpha or v1-alpha2, clone the v1performance repo:
      • cd test
      • git clone https://github.com/dongmingh/v1performance
      • cd v1performance
      • If testing v1.0.0-alpha: git reset --hard aa73747ccf5f511fbcd10a962dd1e588bde1a8b0
    • If testing against latest Fabric commit, copy from Fabric repo:
      • cp -r $GOPATH/src/github.com/hyperledger/fabric/test/tools/PTE .
      • cd PTE
  4. Create Service Credentials file(s) for your Fabric network:

    • See the examples in SCFiles and change the address to your own Fabric addresses and credentials. Add a block for each organization and peer, ensuring correctness.
  5. Specify run scenarios:

    • Create your own version of runCases.txt and User Input json files, according to the test requirements. Use the desired chaincode name, channel name, organizations, etc. Using the information in your own network profiles, remember to "create" all channels, and "join" and "install" for each org, to ensure all peers are set up correctly. Additional information can be found below.

Running PTE

Before attempting to run PTE ensure your network is running! If you do not have access to a Fabric network, please see the section on Creating a local Fabric network.

Usage

./pte_driver.sh <run cases file>

Example

./pte_driver.sh userInputs/runCases.txt

userInputs/runCases.txt contains the list of user specified test cases to be executed. Each line is a test case and includes two parameters: SDK type and user input file.

For instance, a run cases file containing two test cases using the node SDK would be:

sdk=node userInputs/samplecc-chan1-i.json
sdk=node userInputs/samplecc-chan2-i.json

Note: Available SDK types are node, go, python and java; however, only the node SDK is currently supported.

See User Input file in the Reference section below for more information about these files.

Transaction Execution

A single test case is described by a user input file. User input files define all the parameters for executing a test; including transaction type, number of threads, number of transactions, duration, etc. All threads in one test case will concurrently execute the specified transaction. Different transactions may be used in different test cases and then combined into a single run cases file, making it possible to create more complicated scenarios. For example, in a single run of PTE, a user could send a specific number of invokes to all peers and then query each peer separately.

There are two ways to control transaction execution:

  • transaction number: Each thread executes the specified number of transactions specified by nRequest in the user input file.
  • run time duration: Each thread executes the same transaction concurrently for the specified time duration specified by runDur in the user input file, note that nRequest is set to 0.
Transaction Type
  • Invoke (move)
    To execute invoke (move) transactions, set the transType to Invoke and invokeType to Move, and specify the network parameters and desired execution parameters:
    "invokeCheck": "TRUE",
    "transMode": "Constant",
    "transType": "Invoke",
    "invokeType": "Move",
    "nOrderer": "1",
    "nOrg": "2",
    "nPeerPerOrg": "2",
    "nProc": "4",
    "nRequest": "1000",
    "runDur": "600",
    "TLS": "Disabled",
    
    And set the channel name in channelOpt:
    "channelOpt": {
        "name": "testChannel1",
        "action":  "create",
        "orgName": [
            "testOrg1"
        ]
    },
    
  • Invoke (query)
    To execute invoke (move) transactions, set the transType to Invoke and invokeType to Query, and specify the network parameters and desired execution parameters:
    "invokeCheck": "TRUE",
    "transMode": "Constant",
    "transType": "Invoke",
    "invokeType": "Query",
    "nOrderer": "1",
    "nOrg": "2",
    "nPeerPerOrg": "2",
    "nProc": "4",
    "nRequest": "1000",
    "runDur": "600",
    "TLS": "Disabled",
    
    And set the channel name in channelOpt:
    "channelOpt": {
        "name": "testChannel1",
        "action":  "create",
        "orgName": [
            "testOrg1"
        ]
    },
    
Sample Use Cases
  • Latency
    Example: userInputs/samplecc-latency-i.json Performs 1000 invokes (Move) with 1 thread on 1 network using the sample_cc chaincode. The average of the execution result (execution time (ms)/1000 transactions) represents the latency of 1 invoke (Move).
  • Long run
    Example: userInputs/samplecc-longrun-i.json Performs invokes (Move) of various payload size ranging from 1kb-2kb with 1 threads on one network using sample_cc chaincode for 72 hours at 1 transaction per second.
  • Concurrency
    Example: userInputs/samplecc-concurrency-i.json Performs invokes (Move) of 1kb payload with 50 threads on one 4-peer network using sample_cc chaincode for 10 minutes.
  • Complex
    Example: userInputs/samplecc-complex-i.json Performs invokes (Move) of various payload size ranging from 10kb-500kb with 10 threads on one 4-peer network using sample_cc chaincode for 10 minutes. Each invoke (Move) is followed by an invoke (Query).
  • More complicated scenarios
    • For multiple different chaincode deployments and transactions, configure each user input file to deploy different chaincodes and drive the transactions appropriately.
    • For a density test, configure multiple SCFiles, one for each network. Then concurrently execute the test against these multiple networks with unique workloads specified in the user input files.
    • For a stress test on a single network, set all SCFiles to same network. Then concurrent execution of the test is performed against the network but with the workload specified in each user input file.

Additional Use Cases

Although PTE's primary use case is to drive transactions into a Fabric network, it can be used for creating and joining channels, and chaincode installation and instantiation. This gives the ability for more complete end-to-end scenarios.

  • Channel Operations
    For any channel activities (create or join), set transType to Channel:
    "transMode": "Simple",
    "transType": "Channel",
    "invokeType": "Move",
    
    • Create a channel
      To create a channel, set the action in channelOpt to create, and set the name to the channel name. Note that orgName is ignored in this operation:
      "channelOpt": {
          "name": "testChannel1",
          "action":  "create",
          "orgName": [
              "testOrg1"
          ]
      },
      
    • Join a channel
      To join all peers in an org to a channel, set the action in channelOpt to join, set name to channel name, and set orgName to the list of orgs to join:
      "channelOpt": {
          "name": "testChannel1",
          "action":  "join",
          "orgName": [
              "testOrg1"
          ]
      },
      
  • Chaincode Operations
    For chaincode setup (install or instantiate) set deploy according to the test. For example:
    "deploy": {
        "chaincodePath": "github.com/sample_cc",
        "fcn": "init",
        "args": []
    },
    
    • Install a chaincode
      To install a chaincode, set the transType to install:
      "transMode": "Simple",
      "transType": "install",
      "invokeType": "Move",
      
      And set channelOpt name to the channel name and orgName to a list of org names:
      "channelOpt": {
          "name":  "testChannel1",
          "action":  "create",
          "orgName": [
              "testOrg1"
          ]
      },
      
      Note that action is ignored.
    • Instantiate a chaincode
      To instantiate a chaincode, set the transType to instantiate:
      "transMode": "Simple",
      "transType": "instantiate",
      "invokeType": "Move",
      
      and set channelOpt name to the channel name:
      "channelOpt": {
          "name":  "testChannel1",
          "action":  "create",
          "orgName": [
              "testOrg1"
          ]
      },
      
      Note that action and orgName are ignored.

Chaincodes

The following chaincodes are tested and supported:

  • example02: This is a simple chaincode with limited capability. This chaincode is NOT suitable for performance benchmark.
  • ccchecker: This chaincode supports variable payload sizes. See userInput-ccchecker.json for example of userInput file. Take the following steps to install this chaincode:
    • cd $GOPATH/src/github.com/hyperledger/fabric-sdk-node/test/fixtures/src/github.com
    • mkdir ccchecker
    • download newkeyperinvoke.go into ccchecker directory
  • sample_cc: This chaincode supports variable (randomized) payload sizes and performs encryption and decryption on the payload. Specify ccType as ccchecker when using this chaincode. See userInput-samplecc.json for example of userInput file. Take the following steps to install this chaincode:
    • cd $GOPATH/src/github.com/hyperledger/fabric-sdk-node/test/fixtures/src/github.com
    • mkdir sample_cc
    • download chaincode_sample.go into sample_cc directory

Output

The output includes network id, thread id, transaction type, total transactions, completed transactions, failed transactions, starting time, ending time, and elapsed time.

  • For example, consider a test case that has 4 threads driving a single peer. The output shows that network 0 thread 0 executed 1000 moves with no failure in 406530 ms, network 0 thread 1 executed 1000 moves with no failure in 400421 ms, and so on. Note that the starting and ending timestamps are provided:
    stdout: [Nid:id=0:3] eventRegister: completed 1000(1000) Invoke(Move) in 259473 ms, timestamp: start 1492024894518 end 1492025153991
    stdout: [Nid:id=0:2] eventRegister: completed 1000(1000) Invoke(Move) in 364174 ms, timestamp: start 1492024894499 end 1492025258673
    stdout: [Nid:id=0:1] eventRegister: completed 1000(1000) Invoke(Move) in 400421 ms, timestamp: start 1492024894500 end 1492025294921
    stdout: [Nid:id=0:0] eventRegister: completed 1000(1000) Invoke(Move) in 406530 ms, timestamp: start 1492024894498 end 1492025301028

Creating a local Fabric network

  • If you do not yet have the Fabric docker images in your local docker registry, please either build them from Fabric source or download them from dockerhub.
    • cd $GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli/
    • sh ./download-dockerimages.sh -c x86_64-1.0.0-alpha2 -f x86_64-1.0.0-alpha2
  • If you do not have an existing network already, you can start a network using the Fabric e2e example:
    • cd $GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli/
    • Edit network_setup.sh and change COMPOSE_FILE:
      #COMPOSE_FILE=docker-compose-cli.yaml
      COMPOSE_FILE=docker-compose-e2e.yaml
      
    • ./network_setup.sh up
  • Alternatively, consider using the NetworkLauncher tool:
    • cd $GOPATH/src/github.com/hyperledger/fabric-sdk-node/test
    • git clone https://github.com/dongmingh/v1Launcher
    • cd v1Launcher
    • ./NetworkLauncher.sh -?
