Getting Started

Prerequisites

• an AWS account
• npm is installed
• the AWS CLI is installed and configured
• an AWS named profile
• the AWS CDK command-line tool is installed

Installation

• run npm install -g monsoon-load-testing [TODO: UPDATE NPM PACKAGE LINK]
• type monsoon --help to see all the available commands

First Time Usage

The monsoon command is run by inputting subcommands after the initial monsoon command, e.g. monsoon <subcommand>.

To read the help text for each command, type monsoon <command> --help. This outputs a short explanation of what the command does and how to use it.

• cd to the folder in which you would like to initialize your Monsoon directory

• type monsoon init. You will be prompted for your AWS credentials, including the name of your CLI profile. A new monsoon_tests subdirectory will be created inside your current working directory. You will need to cd into monsoon_tests and be sure to execute all of the other monsoon CLI subcommands from monsoon_tests.

• Your Monsoon infrastructure information can be found in ~/.monsoon/.env:

  • AWS_ACCESS_KEY_ID
  • AWS_SECRET_KEY
  • AWS_PROFILE

• type monsoon config if you need to edit your AWS credentials.

• Once inside monsoon_tests, type monsoon new-test to create a new test folder that will include a test_script.js template and a default test_config.json file that you can update to set the parameters for your current test.

• type monsoon list to see all current test directories.

• type monsoon deploy to deploy the infrastructure.

• monsoon start will prompt you to select the test directory that contains the test you want Monsoon to run.

• type monsoon weather-channel to start the local server that serves the results dashboard. To view this dashboard, visit localhost:5000.

Removing Monsoon

To remove your Monsoon infrastructure from AWS, run monsoon teardown.

To remove the Monsoon global directory, run monsoon destroy. Be sure to run monsoon teardown first -- otherwise the monsoon teardown command cannot use your AWS credentials to tear down the infrastructure.

To uninstall / remove the Monsoon CLI tool, run npm uninstall -g monsoon-load-testing.

FAQ

I quit monsoon deploy in the middle of deploying the infrastructure -- is there a way to tear down the infrastructure?

• AWS will continue to set up your infrastructure even if you interrupt the Monsoon CLI command. You'll need to manually tear it down by visiting the he AWS console, navigating to the CloudFormation section and deleting the monsoon stack. Note that the infrastructure deployment must be completed before AWS will allow you to delete the stack.

I ran monsoon destroy and now cannot run monsoon teardown -- is there a way to tear down the infrastructure?

• monsoon destory deletes your Monsoon .env file. Make sure to run monsoon config again with correct information, then you can run monsoon teardown.
