SMS Alerts in Grafana using a Custom Webhook and AWS SNS
I will show you how you can create an alert channel in Grafana using a custom webhook that sends SMS. The SMS gateway I will use is AWS SNS.
You will need an AWS account. Log in and create an IAM user, and add it to a group with the AmazonSNSFullAccess policy. Take note of the Access Key and Secret given to you by AWS.
