Stress test of Unreal Engine 4 Dedicated Server

A tool that leverages AWS to see how much client an UE4 dedicated server can handle.

Prerequisites

Before using this tool, the following needs to be installed on both EC2 instances (via AMI) and your computer:

AWS CLI

https://aws.amazon.com/cli/

Mac OS X

brew install awscli

Linux (Ubuntu)

sudo apt-get install python-pip

# Install AWS CLI using pip
# To upgrade an existing AWS CLI installation, use the --upgrade option:
#   sudo pip install --upgrade awscli
sudo pip install awscli

# Enable Command Completion for AWS CLI
echo 'complete -C $(which aws_completer) aws' >> ~/.bash_completion

jq

https://stedolan.github.io/jq/

Mac OS X

brew install jq

Linux (Ubuntu)

sudo apt-get install jq

Configure

All configuration files are in conf/[env] directory.

Default configs are in conf/_default directory, they are loaded first, copy them to another directory to override the default value.

Run

Launch server:

./launch-server.sh [env]

Launch clients:

./launch-client.sh [env] [instance-count]

Terminate server:

./terminate-server.sh [env]

Terminate clients:

./terminate-clients.sh [env]

View Results

Two custom metrics of the server are posted to AWS CloudWatch:

Client

How many client are currently online.

CPU

How much percentage the server process utilizes the CPU (100% means occupies 1 entire core).
