AHA is an incident management & communication framework to provide real-time alert customers when there are active AWS event(s). For customers with AWS Organizations, customers can get aggregated active account level events of all the accounts in the Organization. Customers not using AWS Organizations still benefit alerting at the account level.

Configuring an Endpoint

AHA can send to multiple endpoints (webhook URLs, Email or EventBridge). To use any of these you'll need to set it up before-hand as some of these are done on 3rd party websites. We'll go over some of the common ones here.

Creating a Amazon Chime Webhook URL

You will need to have access to create a Amazon Chime room and manage webhooks.

  1. Create a new chat room for events (i.e. aws_events).
  2. In the chat room created in step 1, click on the gear icon and click manage webhooks and bots.
  3. Click Add webhook.
  4. Type a name for the bot (e.g. AWS Health Bot) and click Create.
  5. Click Copy URL, we will need it for the deployment.

Creating a Slack Webhook URL

You will need to have access to add a new channel and app to your Slack Workspace.

Webhook

  1. Create a new channel for events (i.e. aws_events)
  2. In your browser go to: workspace-name.slack.com/apps where workspace-name is the name of your Slack Workspace.
  3. In the search bar, search for: Incoming Webhooks and click on it.
  4. Click on Add to Slack.
  5. From the dropdown click on the channel your created in step 1 and click Add Incoming Webhooks integration.
  6. From this page you can change the name of the webhook (i.e. AWS Bot), the icon/emoji to use, etc.
  7. For the deployment we will need the Webhook URL.

Workflow

  1. Create a new channel for events (i.e. aws_events)
  2. Within Slack click on your workspace name drop down arrow in the upper left. click on Tools > Workflow Builder
  3. Click Create in the upper right hand corner of the Workflow Builder and give your workflow a name click next.
  4. Click on select next to Webhook and then click add variable add the following variables one at a time in the Key section. All data type will be text:
    -text
    -accounts
    -resources
    -service
    -region
    -status
    -start_time
    -event_arn
    -updates
  5. When done you should have 9 variables, double check them as they are case sensitive and will be referenced. When checked click on done and next.
  6. Click on add step and then on the add a workflow step click add next to send a message.
  7. Under send this message to: select the channel you created in Step 1 in message text you can should recreate this following:
  8. Click save and the click publish
  9. For the deployment we will need the Webhook URL.

Creating a Microsoft Teams Webhook URL

You will need to have access to add a new channel and app to your Microsoft Teams channel.

  1. Create a new channel for events (i.e. aws_events)
  2. Within your Microsoft Team go to Apps
  3. In the search bar, search for: Incoming Webhook and click on it.
  4. Click on Add to team.
  5. Type in the name of your on the channel your created in step 1 and click Set up a connector.
  6. From this page you can change the name of the webhook (i.e. AWS Bot), the icon/emoji to use, etc. Click Create when done.
  7. For the deployment we will need the webhook URL that is presented.

Configuring an Email

  1. You'll be able to send email alerts to one or many addresses. However, you must first verify the email(s) in the Simple Email Service (SES) console.
  2. AHA utilizes Amazon SES so all you need is to enter in a To: address and a From: address.
  3. You may have to allow a rule in your environment so that the emails don't get labeled as SPAM. This will be something you have to congfigure on your own.

Creating a Amazon EventBridge Ingestion ARN

Only required if you are going to be using EventBridge, you can create new with the instructions below or use an existing one.

  1. In the AWS Console, search for Amazon EventBridge.
  2. On the left hand side, click Event buses.
  3. Under Custom event bus click Create event bus
  4. Give your Event bus a name and click Create.
  5. For the deployment we will need the Name of the Event bus (not the ARN, e.g. aha-eb01).

Deployment Options

Using AWS Health Delegated Administrator with AHA

NOTE: For users with company restrictions of use/deployment of resources in the organization management account.

On 2023-07-27, AWS Health released the Delegated Administrator feature. By enabling an account as a delegated administrator, you can use AHA in Organization Mode without the need to create and assume the management account IAM role.

To enable this feature:

  1. Know the AWS Account ID of your AWS account you want to enable as a delegated administrator for AWS Health (e.g. 123456789012)

  2. In the Org Management Account, run the command aws organizations register-delegated-administrator --account-id ACCOUNT_ID --service-principal health.amazonaws.com replacing ACCOUNT_ID with the ID of your Member Account

  3. Deploy AHA in your deletegated administrator account using the steps for:

    1. AHA for users who ARE using AWS Organizations (CloudFormation)
    2. AHA for users who ARE using AWS Organizations (Terraform)

CloudFormation

There are 3 available ways to deploy AHA, all are done via the same CloudFormation template to make deployment as easy as possible.

The 3 deployment methods for AHA are:

  1. AHA for users WITHOUT AWS Organizations: Users NOT using AWS Organizations.
  2. AHA for users WITH AWS Organizations (Management Account): Users who ARE using AWS Organizations and deploying in the top-level management account.
  3. AHA for users WITH AWS Organizations (Member Account): Users who ARE using AWS Organizations and deploying in a member account in the organization to assume a role in the top-level management account.

AHA Without AWS Organizations using CloudFormation

Prerequisites

  1. Have at least 1 endpoint configured (you can have multiple)
  2. Have access to deploy Cloudformation Templates with the following resources: AWS IAM policies, Amazon DynamoDB Tables, AWS Lambda, Amazon EventBridge and AWS Secrets Manager.
  3. If using Multi-Region, you must deploy the following 2 CloudFormation templates to allow the Stackset deployment to deploy resources even if you have full administrator privileges, you still need to follow these steps.

Deployment

  1. Clone the AHA package that from this repository. If you're not familiar with the process, here is some documentation. The URL to clone is in the upper right-hand corner labeled Clone uri
  2. In the root of this package you'll have two files; handler.py and messagegenerator.py. Use your tool of choice to zip them both up and name them with a unique name (e.g. aha-v1.8.zip). Note: Putting the version number in the name will make upgrading AHA seamless.
  3. Upload the .zip you created in Step 1 to an S3 in the same region you plan to deploy this in.

Updating using CloudFormation

Until this project is migrated to the AWS Serverless Application Model (SAM), updates will have to be done as described below:

  1. Download the updated CloudFormation Template .yml file and 2 .py files.
  2. Zip up the 2 .py files and name the .zip with a different version number than before (e.g. if the .zip you originally uploaded is aha-v1.8.zip the new one should be aha-v1.9.zip)
  3. In the AWS CloudFormation console click on the name of your stack, then click Update.
  4. In the Prepare template section click Replace current template, click Upload a template file, click Choose file, select the newer CFN_DEPLOY_AHA.yml file you downloaded and finally click Next.
  5. In the S3Key text box change the version number in the name of the .zip to match name of the .zip you uploaded in Step 2 (The name of the .zip has to be different for CloudFormation to recognize a change). Click Next.
  6. At the next screen click Next and finally click Update stack. This will now upgrade your environment to the latest version you downloaded.

If for some reason, you still have issues after updating, you can easily just delete the stack and redeploy. The infrastructure can be destroyed and rebuilt within minutes through CloudFormation.

Updating using Terraform

Until this project is migrated to the AWS Serverless Application Model (SAM), updates will have to be done as described below:

  1. Pull the latest code from git repository for AHA.
  2. Update the parameters file terraform.tfvars per your requirement
  3. Copy the terraform template files to directory where your previous state exists
  4. Deploy the templates as below
$ cd aws-health-aware
$ git pull https://github.com/aws-samples/aws-health-aware.git
$ cd terraform/Terraform_DEPLOY_AHA
$ terraform init
$ terraform plan - This command should show any difference existing config and latest code.
$ terraform apply

If for some reason, you still have issues after updating, you can easily just delete the stack and redeploy. The infrastructure can be destroyed and rebuilt within minutes through Terraform.

New Features

Release 2.2

We are happy to announce the launch of new enhancements to AHA. Please try them out and keep sending us your feedback!

  1. A revised schema for AHA events sent to EventBridge which enables new filtering and routing options. See the new AHA event schema readme for more detail.
  2. Multi-region deployment option
  3. Updated file names for improved clarity
  4. Ability to filter accounts (Refer to AccountIDs CFN parameter for more info on how to exclude accounts from AHA notifications)
  5. Ability to view Account Names for a given Account ID in the PHD alerts
  6. If you are running AHA with the Non-Org mode, AHA will send the Account #' and resource(s) impacts if applicable for a given alert
  7. Ability to deploy AHA with the Org mode on a member account
  8. Support for a new Health Event Type - "Investigation"
  9. Terraform support to deploy the solution

Troubleshooting

  • If for whatever reason you need to update the Webhook URL; just update the CloudFormation or terraform Template with the new Webhook URL.
  • If you are expecting an event and it did not show up it may be an oddly formed event. Take a look at CloudWatch > Log groups and search for the name of your Lambda function. See what the error is and reach out to us email for help.
  • If for any errors related to duplicate secrets during deployment, try deleting manually and redeploy the solution. Example command to delete SlackChannelID secret in us-east-1 region.
