Usage

  • deploy-contract-public-4node.jmx fire transactions to deploy new contracts to all 4 nodes in the network in parallel via json-rpc requests. The contract being deployed is a SimpleStorage contract, with a random value being initialised in the constructor.

    Parameters that can be specified include

    • threads : Number of threads per node used to send transactions (i.e. threads=1 means 4 threads to send to 4 nodes)
    • seconds : Duration of the test run in seconds
    • delay : Startup delay (default to 5 seconds)
    • throughput : (value is transactions per minute). Only specify this if you want to throttle the throughput so transactions can be sent slower
    • influxdburl : influxdb url for capturing metrics. Refer here on how to disable influxdb.

    and

    • url$i : The RPC endpoint url
    • port$i : The RPC endpoint port
    • from$i : Geth account used to send transactions from

    with $i being value 1..4 corresponding to node1 to node4 of the network

    Sample usage

    #!/bin/bash
#without influxdb
jmeter -n -t deploy-contract-public-4node.jmx 
     -Jurl1=localhost -Jport1=22000 -Jfrom1=0xed9d02e382b34818e88b88a309c7fe71e65f419d

  • deploy-contract-private-4node.jmx similarly fire transactions to deploy new private SimpleStorage contracts to all 4 nodes in the network in parallel with a privateFor recipient. The contracts are also being initialised with random value.

    Parameters are similar to the above, with an extra variable

    • privateFor$i : Public key of the private recipient

    with $i being value 1..4 corresponding to node1 to node4 of the network

    Sample usage

     #!/bin/bash
 #without influxdb
 jmeter -n -t deploy-contract-private-4node.jmx 
      -Jurl1=localhost -Jport1=22000 -Jfrom1=0xed9d02e382b34818e88b88a309c7fe71e65f419d -JprivateFor1=\"BULeR8JyUWhiuuCMU/HLA0Q5pzkYT+cHII3ZKBey3Bo=\"

      -Jthreads=1 -Jseconds=60

Note: threads$i parameter can also be used to customized the number of threads used for a spefic node - or to disable sending transactions for that particular node

Example

   #!/bin/bash
   #without influxdb
   jmeter -n -t deploy-contract-public-4node.jmx 
   -Jurl1=localhost -Jport1=22000 -Jfrom1=0xed9d02e382b34818e88b88a309c7fe71e65f419d 
   -Jurl2=localhost -Jport2=22001 -Jfrom2=0x4204266650c946a56da82dfded6029cd8b1b54cf
   -Jthreads=1 -Jseconds=60
   -Jthreads3=0 -Jthreads4=0

   #with influxdb
   jmeter -n -t deploy-contract-public-4node.jmx 
   -Jinfluxdburl=http://localhost:8086/write?db=telegraf    
   -Jurl1=localhost -Jport1=22000 -Jfrom1=0xed9d02e382b34818e88b88a309c7fe71e65f419d 
   -Jurl2=localhost -Jport2=22001 -Jfrom2=0x4204266650c946a56da82dfded6029cd8b1b54cf
   -Jthreads=1 -Jseconds=60
   -Jthreads3=0 -Jthreads4=0

The command above will start 2 threads to send transactions to node1 and node2 only

As there are many properties required, these can also be put into a properties file and given to the test execution via command line.

Example property file vars.properties

#Node 1
from1=0x4204266650c946a56da82dfded6029cd8b1b54cf
url1=3.10.116.15
port1=22000

#Node2
from2=0xca40127ac0880f44bca898fd357557b70a2fcc42
url2=35.176.231.84
port2=22001

#Node3
from3=0x53a52871988c3b3856280181105d0541d78b38ac
url3=3.9.17.190
port3=22002

#Node4
from4=0xa13ced78febcac20a8268b796a9e0208c17d8313
url4=35.178.199.42
port4=22003


threads=1
seconds=10
delay=5

influxdburl=http://localhost:8086/write?db=telegraf

Test will then be executed using the following command

jmeter -n -t deploy-contract-public-4node.jmx -q vars.properties

Note that -q option was used to specify additional property file, instead of -p which will replace the whole existing default jmeter.properties file
