Forward AWS CloudWatch Alarms and other notifications from Amazon SNS to Slack.

AWS-to-Slack is a Lambda function written in Node.js that forwards alarms and notifications to a dedicated Slack channel. It self-hosted in your own AWS environment and doesn't have any 3rd party dependencies other than the Google Charts API for rendering CloudWatch metrics.

Supported notification formats:

• AWS Health Dashboard 🆕
• CloudWatch Alarms (incl. Metrics)
• Elastic Beanstalk
• RDS
• Generic SNS messages
• Plain text messages

Additional formats will be added; Pull Requests are welcome!

Ready to try it for yourself? Installation into your own AWS environment is as simple as pressing the button below:

The Lambda function communicates with Slack through a webhook:

1. Navigate to https://slack.com/apps/A0F7XDUAZ-incoming-webhooks and click "Add Configuration".
2. Choose the default channel where messages will be sent and click "Add Incoming WebHooks Integration".
3. Copy the webhook URL from the setup instructions and use it in the next section.
4. Click "Save Settings" at the bottom of the Slack integration page.

Launch the CloudFormation Stack by using our preconfigured CloudFormation template or by simply pressing the following button:

Click "Next" and on the following page name your new stack and paste the webhook URL from before into the "HookUrl" field. You can also configure a different channel to post to if wanted.

Click "Next" again, complete the stack setup on the following pages and finally launch your stack.

Before the Lambda function will actually do anything you need to subscribe it to actual CloudWatch alarms and other SNS triggers. Open up the AWS Lambda, switch to the "Triggers" tab and subscribe for all events you're interested in.

You want to contribute? That's awesome! 🎉

Check out our issues page for some ideas how to contribute and a list of open tasks. There're plenty of notification formats that still need to be supported.

The repository comes with a very simple Makefile to build the CloudFormation stack yourself. Simply run

make deps
make package
