  • JRE 11
  • JRE 17

Add the JAVA_HOME setting to the “~/.loadtester” on the virtual machine.

  • Using JRE 11: export JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"

Example using for JRE 11.

export JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"

Please update Ubuntu and software as necessary.

FAQ

  • Can’t connect to virtual machine with Remote Desktop

    • You need to be able to connect to virtual macine via TCP/3389 port. Please check the following.
      • Is it set to allow TCP/3389 inbound rule with Azure NSG assigned to subnet or NIC?
      • In the case of via Azure LoadBalancer, is the LoadBalancer properly forwarding to TCP/3389 of the virtual machine?

  • OS does not start normally / Can’t login to Remote Desktop

    • 2GB or more of OS memory is required to operate the virtual machine normally

      Change the Azure Virtual machine to the appropriate size.

  • Apache JMeter™ does not start due to lack of memory

    • Adjust the heap memory size used by JMeter by specifying -Xms and -Xms in the JVM_ARGS environment variable

      Example of setting -Xms and -Xmx of JVM_ARGS environment variables to 64MB and 128MB in ~/.loadtester

      export JVM_ARGS="-Xms64m -Xmx128m"
