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
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 recomends these CloudWatch alarms as a means of monitoring an OpenSearch domain
