How do I set a monthly spending limit alarm for SMS messages in Amazon SNS

Hello Ritesh, To set up a monthly spending limit alarm for SMS messages in Amazon SNS, you can utilize the SMSMonthToDateSpentUSD metric. Here's how to do it:

1. Open the CloudWatch console in AWS.
2. Navigate to "Alarms" and click "Create alarm".
3. Select "SNS" under AWS namespaces, then choose "Topic Metrics".
4. Find and select the SMSMonthToDateSpentUSD metric.
5. When configuring the alarm:
   • Set the statistic to Sum
   • Choose an appropriate period (e.g., 1 hour)
   • Define your threshold based on your monthly budget
6. Set up notifications for when the alarm state changes to "In alarm".
7. Name your alarm descriptively and create it.

This setup will alert you when your SMS spending approaches or exceeds your defined limit. For more detailed information, please refer to the AWS documentation: https://docs.aws.amazon.com/sns/latest/dg/sns-monitoring-using-cloudwatch.html By using the Sum statistic, you'll get an accurate representation of your total monthly SMS spend, allowing for better cost management and budget control.
