Sns To Slack Python

In SNS topics, choose the name of the Amazon SNS topic you configured as the notification rule target. Choose Configure. (Optional) To test the integration, make a change in the resource that matches an event type for a notification rule that is configured to use the Amazon SNS topic as its target. 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. Some information on those, e.g. High load, would be nice to be notified of. Preferably on Slack. How do I do that? Part 1: Send alarms to an SNS Topic. Using awscli on a local machine, create a new SNS Topic. What's an SNS Topic, you say?

Amazon Web Services Inc. said today that its AWS Chatbot service for sending notifications to DevOps teams is now generally available.

Launched in beta in June 2019, AWS Chatbot enables security, billing and system stability alerts to be sent to DevOps teams via the popular collaboration tool Slack. The service delivers alerts from several important AWS services, including Amazon Cloud Watch, AWS Health, AWS Budgets, AWS Security Hub, Amazon GuardDuty and AWS CloudFormation.

It takes its cue from the Amazon Simple Notification Service, which sends the same types of notifications to developers’ email inboxes. The messages can also be routed through Amazon’s own Chime collaboration service, the company said.

“AWS Chatbot is a unique and powerful communication tool that has the potential to change the way that you monitor and maintain your cloud environments,” AWS Chief Evangelist Jeff Barr said in a blog post. He said the tool should help teams that are usually engaged with Slack to respond to incidents faster.

AWS Chatbot works by redirecting customers’ SNS topic notifications to developers’ Slack channels or Chime chat rooms. Administrators can add the alerts to Slack from directly within the AWS Chatbot console, though some extra configuration might be required for some services, Amazon said.

The types of notifications it delivers include messages about billing and cost management, operating metrics for Amazon services, security threats, compliance alerts and availability of resources for key applications.

“DevOps teams can receive real-time notifications that help them monitor their systems from within Slack,” the Slack team wrote in a blog post. “That means they can address situations before they become full-blown issues, whether it’s a budget deviation, a system overload or a security event.”

“The future of work is to meet people where they work, and that is in dialogue-based applications like Microsoft Teams or Slack,” said Holger Mueller, an analyst with Constellation Research Inc. “So it’s no surprise that AWS Chatbot has a plugin for Slack, giving developers and DevOps teams better access to a wide range of AWS notifications.”

AWS Chatbot is available now at no cost, with users instead billed for the underlying AWS services they use.

As we all know, things go wrong. That’s why monitoring and alerting are essential topics. Wouldn’t it be nice, if problems in your AWS account would show up in Slack? So you can react quickly while using your favorite messaging tool. In this blog post, you will learn how you can turn CloudWatch Alarms into Slack messages like this:

How it works

On AWS, everything sends monitoring data (CPU utilization, estimated monthly charges, …) to CloudWatch. In CloudWatch, you define alarms to send a message to an SNS topic if the monitoring data gets out of normal bounds. Finally, you connect a Lambda function to the SNS topic to trigger a function execution. The Lambda function calls the Slack API to send a message. The following figure shows the data flow:

To deploy the components in the figure, you will use the Serverless Application Model (SAM). If you are not interested in implementing this on your own, give our Slack chatbot a try. Never miss an alert from your AWS infrastructure with marbot!

Implementing the Lambda function

Sns To Slack

You will use Node.js to implement the Lambda function. To send a request to the Slack API, you have to make an HTTPS request. The request module is easy to use, but I wanted a variant of the module that returns promises to avoid callback hell. That’s why I used request-promise-native. The Slack webhook URL is passed in as an environment variable that you define later in the CloudFormation template.

Messages delivered from SNS to the Lambda function will look like this:

You need to convert the format into the Slack message format.

Finally, each Lambda function needs a handler function. The handler function takes 3 parameters:
