Stress testing for java-tron's gRPC

lever

lever is a stress testing tool for java-tron.

How to use?

Run a private blockchain of java-tron

Read the Start Private Blockchain. Two accounts need to be reserved, one for initiating the transfer and one for receiving the transfer amount.

Jmeter

  1. Install Jmeter.

lever

  1. Generate jar and run test:
$ git clone https://github.com/tronprotocol/lever.git
$ cd lever
$ ./gradlew build
$ ./gradlew clean shadowJar -PmainClass=org.tron.program.RpcHunterSendCoin
$ cp build/libs/org.tron.program.RpcHunterSendCoin.jar jmeter/lib/ext/org.tron.program.RpcHunterSendCoin.jar
$ cp src/main/resources/jmeter-setting.jmx jmeter/bin/
$ cd jmeter/bin
$ ./jmeter -n -t /jmeter-setting.jmx -l test_result.jtl -e -o /resultReport
  1. Configuration

2.1 config.conf

lever/src/main/resources/config.conf：

grpc.address = "127.0.0.1:50051" # target gRPC server address

2.2 jmeter-setting.jmx

lever/src/main/resources/jmeter-setting.jmx：

10 threads running for 1800 seconds：

  <ThreadGroup guiclass="ThreadGroupGui" testclass="ThreadGroup" testname="Thread Group" enabled="true">
    <stringProp name="ThreadGroup.on_sample_error">continue</stringProp>
    <elementProp name="ThreadGroup.main_controller" elementType="LoopController" guiclass="LoopControlPanel" testclass="LoopController" testname="Loop Controller" enabled="true">
      <boolProp name="LoopController.continue_forever">false</boolProp>
      <intProp name="LoopController.loops">-1</intProp>
    </elementProp>
    <stringProp name="ThreadGroup.num_threads">10</stringProp>
    <stringProp name="ThreadGroup.ramp_time">1</stringProp>
    <boolProp name="ThreadGroup.scheduler">true</boolProp>
    <stringProp name="ThreadGroup.duration">1800</stringProp>
    <stringProp name="ThreadGroup.delay"></stringProp>
  </ThreadGroup>

Transaction arguments(put your arguments: Argument.value to this file):

<JavaSampler guiclass="JavaTestSamplerGui" testclass="JavaSampler" testname="Java Request" enabled="true">
  <elementProp name="arguments" elementType="Arguments" guiclass="ArgumentsPanel" testclass="Arguments" enabled="true">
    <collectionProp name="Arguments.arguments">
      <elementProp name="toAddress" elementType="Argument">
        <stringProp name="Argument.name">toAddress</stringProp>
        <stringProp name="Argument.value">27d3byPxZXKQWfXX7sJvemJJuv5M65F3vjS</stringProp>
        <stringProp name="Argument.metadata">=</stringProp>
      </elementProp>
      <elementProp name="amount" elementType="Argument">
        <stringProp name="Argument.name">amount</stringProp>
        <stringProp name="Argument.value">1</stringProp>
        <stringProp name="Argument.metadata">=</stringProp>
      </elementProp>
      <elementProp name="privateKey" elementType="Argument">
        <stringProp name="Argument.name">privateKey</stringProp>
        <stringProp name="Argument.value">effa55b420a2fe39e3f73d14b8c46824fd0d5ee210840b9c27b2e2f42a09f1f9</stringProp>
        <stringProp name="Argument.metadata">=</stringProp>
      </elementProp>
    </collectionProp>
  </elementProp>
  <stringProp name="classname">org.tron.program.RpcHunterSendCoin</stringProp>
</JavaSampler>

Throughout setting(60/s):

<ConstantThroughputTimer guiclass="TestBeanGUI" testclass="ConstantThroughputTimer" testname="Constant Throughput Timer" enabled="true">
  <doubleProp>
    <name>throughput</name>
    <value>60.0</value>
    <savedValue>0.0</savedValue>
  </doubleProp>
  <intProp name="calcMode">1</intProp>
</ConstantThroughputTimer>

You can use generate-account-tool to generate your account and put it to java-tron's config.conf: genesis.block.assets, genesis.block.witnesses, localwitness

lever's Issues

shadowJar has no value specified for property 'mainClassName'

Hi there,
I have a clean install of java-tron from the develop branch today. I tried to follow your instructions exactly, but received the following errors (after a successful ./gradlew build):

rafeeki@rafeeki:~/GitHub/java-tron$ ./gradlew clean shadowJar -PmainClass=org.tron.program.RpcHunterSendCoin

> Task :generateProto UP-TO-DATE
Using TaskInputs.file() with something that doesn't resolve to a File object has been deprecated and is scheduled to be removed in Gradle 5.0. Use TaskInputs.files() instead.

> Task :compileJava 
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

> Task :shadowJar 
A problem was found with the configuration of task ':shadowJar'. Registering invalid inputs and outputs via TaskInputs and TaskOutputs methods has been deprecated and is scheduled to be removed in Gradle 5.0.
 - No value has been specified for property 'mainClassName'.

rafeeki@rafeeki:~/GitHub/java-tron$ cp build/libs/org.tron.program.RpcHunterSendCoin jmeter/lib/ext/org.tron.program.RpcHunterSendCoin
cp: cannot stat 'build/libs/org.tron.program.RpcHunterSendCoin': No such file or directory

Please advise, I would really like to stress test the Tron testnet.

README Suggestion

I found some of the commands in the README need to be cleaned up. The first instance is the cp command needs the .jar extension or it can't find the file:

cp build/libs/org.tron.program.RpcHunterSendCoin.jar jmeter/lib/ext/org.tron.program.RpcHunterSendCoin

The second instance is when you run jmeter the console gives instructions for running load tests

Don't use GUI mode for load testing !, only for Test creation and Test debugging.
For load testing, use NON GUI Mode:
jmeter -n -t [jmx file] -l [results file] -e -o [Path to web report folder]

From this I get the following

touch recording.xml && mkdir webreports
./jmeter/bin/jmeter -n -t src/main/resources/jmeter-setting.jmx -l recording.xml -e -o webreports
