# OpenSearch CloudWatch Alarms

  

Deploying the CloudFormation Stack in this repository will create CloudWatch Alarms - that will trigger email alerts via. SNS notification - for the metrics documented in the table below.

To deploy the CloudWatch alarms click the button

[![Launch CloudFormation Stack](https://sharkech-public.s3.amazonaws.com/misc-public/cloudformation-launch-stack.png)](https://console.aws.amazon.com/cloudformation/home#/stacks/new?stackName=open-search-cloudwatch-alarms&templateURL=https://sharkech-public.s3.amazonaws.com/misc-public/OpenSearch_cloudwatch_alarms.yaml)

When prompted by CloudFormation enter the name of the OpenSearch domain to monitor and the email address you want notifications to be send to

[AWS documention](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/cloudwatch-alarms.html) recomends these CloudWatch alarms as a means of monitoring an OpenSearch domain
