Monitor AWS Elastic Beanstalk

AWS Elastic Beanstalk is a service provided by Amazon Web Services (AWS) that gives you the option of deploying and auto-scaling applications and services.

As this type of installation depends heavily on user customizations, there isn't any set of steps that will work in all scenarios. The following aims to provide an overview of the entire process, with examples to help you create your own deployment.

Prerequisites

Locate the ONEAGENT_INSTALLER_SCRIPT_URL. This information is shared during Dynatrace OneAgent installation.

To get your ONEAGENT_INSTALLER_SCRIPT_URL

In Dynatrace Hub, select OneAgent.
Select Set up > Linux.
Determine the installer script URL and token from the UI-provided wget command:

This is the URL:

OneAgent URL

Replace the value of arch parameter with <arch>. Ignore the flavor=default parameter.
For the API-Token value, you need a PaaS token.

Your URL should look like this: https://host.domain.com/api/v1/deployment/installer/agent/unix/default/latest?arch=<arch>

This is your ONEAGENT_INSTALLER_SCRIPT_URL.

This your URL and API token.

OneAgent installation page with URL to be modified

Append the API token to the URL using the API-Token parameter. Your URL should look like this:

https://host.domain.com/api/v1/deployment/installer/agent/unix/default/latest?arch=x86&flavor=default&Api-Token=<token>

This is your ONEAGENT_INSTALLER_SCRIPT_URL.

Access to the AWS console

For configurations where OneAgent is already part of your application deployment, you don't have to manually install OneAgent or restart servers to enable service monitoring.

Download OneAgent

In Dynatrace Hub, select OneAgent.
Select Set up > Windows or Linux. For more information, see the OneAgent installation instructions for Windows or Linux.

Customize your installation

Make sure the configuration files are properly formatted YAML files.
Don't use tabs for indentation. Only spaces are allowed.
The Elastic Beanstalk extension script file names are important—the Amazon interpreter executes them in alphabetical order.

To install OneAgent, you need two configuration files:

One file for downloading the OneAgent installer
Another file for invoking the installation and post-installation tasks.

In the Beanstalk deployment package, create a .ebextensions directory within the same directory as the main Beanstalk project source code. The two configuration files mentioned above must be placed in this directory.
Create a configuration file for downloading the installer named 0dynatraceDownload.config.

The file must contain a files section that defines:
- The download path and target file name (for example, /tmp/dynatraceinstall.sh)
- Proper user rights settings
- The OneAgent download URL mentioned in the prerequisites.
Example:
```
files:
    "/tmp/dynatraceinstall.sh":
      mode: "000755"
      owner: root
      group: root
      source: "https://abcdefghij.live.dynatrace.com/api/v1/deployment/installer/agent/unix/default/latest?arch=x86&flavor=default&Api-Token=abcdefghijklmnopqrstu"
```
Make sure to replace the generic values in the example above with your own.
Create a configuration file to execute the OneAgent installer and perform other tasks such as service restart, named 1dynatraceInstallAndPost.config.

In the example below, the script checks for an existing OneAgent setup and, if no OneAgent is found, executes the installation from the /tmp directory, setting the --set-proxy=172.1.1.128:8080 installation parameter to connect the agent to a specific proxy. Then the httpd service is restarted.
```
commands:
  install_dynatrace:
    cwd: /tmp
    command: "/bin/sh dynatraceinstall.sh --set-proxy=172.1.1.128:8080"
  restart_httpd:
    command: "service httpd restart"
```
If you want to add more parameters, separate them with spaces. To learn more about installation parameters, see how to customize OneAgent installation on Linux.

Do not use the command's env property because it overwrites, rather than appends, the existing environment and will cause OneAgent installation to fail.

optional Extend your configuration.

You can also include steps to download OneAgent in your configuration.

The example below includes OneAgent download in the configuration. While this is necessary for the first installation of OneAgent, it might substantially lengthen future application updates because you download OneAgent each time you run the script. To improve your Beanstalk configuration, add a check for an existing OneAgent installation and have your scripts download OneAgent only when it isn't found on the system.

Inspect the following Linux configuration example carefully before creating your own scripts. The Amazon interpreter is sensitive to syntax errors. Take care in formatting and escaping special characters.

files:
  "/tmp/dynatraceinstall.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/bin/bash
      if [ ! -d /opt/dynatrace/oneagent ]; then
        wget -O /tmp/Dynatrace-OneAgent.sh "https://abcdefghij.live.dynatrace.com/api/v1/deployment/installer/agent/unix/default/latest?arch=x86&flavor=default&Api-Token=abcdefghijklmnopqrstu"
        chmod 755 /tmp/Dynatrace-OneAgent.sh
        sudo chown root:root /tmp/Dynatrace-OneAgent.sh
        sudo /tmp/Dynatrace-OneAgent.sh
      fi

commands:
  install_dynatrace:
    cwd: /tmp
    command: "/bin/sh dynatraceinstall.sh --set-proxy=172.1.1.128:8080"
  restart_nginx:
    command: service nginx restart
    ignoreErrors: true

To install OneAgent, you need two configuration files:

One file for downloading the OneAgent installer
Another file for invoking the installation and post-installation tasks.

Create a configuration file for downloading the installer named 0dynatraceDownload.config.

The file must contain a sources section that defines:
- The download destination (for example, your desktop)
- The OneAgent download URL mentioned in the prerequisites.
Example:
```
files:
    "C:/OneAgent/Dynatrace-OneAgent-Installer.exe":
        source: "https://abcdefghij.live.dynatrace.com/api/v1/deployment/installer/agent/windows/default-unattended/latest?Api-Token=abcdefghijklmnopqrstu&arch=x86&flavor=default"
```
Make sure to replace the generic values in the example above with your own.
Create a configuration file to execute the OneAgent installer and perform other tasks such as service restart, named 1dynatraceInstallAndPost.config.

The file must contain a commands section that defines the installation command for OneAgent.

Do not use the command's env property because it overwrites, rather than appends, the existing environment and will cause OneAgent installation to fail.

In the example below, the script executes the installer from the administrator's desktop folder in quiet mode (no graphical user interface involved). The file passes the --set-proxy=172.1.1.128:8080 installation parameter to connect the agent to a specific proxy.
```
commands:
    install_oneagent:
        command: "C:/OneAgent/Dynatrace-OneAgent-Installer.exe --quiet --set-proxy=172.1.1.128:8080"
```
If you want to add more parameters, separate them with with spaces. To learn more about installation parameters, see how to customize OneAgent installation on Windows.

You don't need to add extra commands following OneAgent installation. Amazon will restart IIS on its own after you've successfully uploaded all your application files.

Configure network zones optional

To configure network zones, use the following argument: --set-network-zone=<your.network.zone>. See network zones for more information.

Monitoring consumption

For AWS Elastic Beanstalk, monitoring consumption is based on hosts units. See Application and Infrastructure Monitoring (Host Units) for details.
