votes

I am struggling to match CloudWatch metric count (as shown in CloudWatch Console ) with count shown in Billing (Estimate for current month ). Attached here are both screen shots.

1) According to below billing screen shot, I should have 10+9.597 = 19.597 metric Alarms

CloudWatch Billing

2) According to CloudWatch Console, I have only 3 Alarms. Infact I don't remember of creating more.

CloudWatch Console

  1. I have couple of In Alarms, but in current month ( billing period July ), have only one, see screen shot below.

Couple of In Alarms are shown in red, but they are for last month, which is already billed.

1 Alarm in July

Let me know please if you need more information or any specific screen shot from aws console.

4) Output of aws query

aws cloudwatch describe-alarms --query 'MetricAlarms[*].[AlarmName]' --region us-east-2 > metric-alarams

Do a aws cloudwatch describe-alarms --query 'MetricAlarms[*].[AlarmName]' --region us-east-2 and see how many alarms are listed. – jellycsc
@jellycsc - thanks, I run that query and updated results in Answer. There are 29 records, and except last one all are automatically generated while creating DynmoDB table. Does AWS consider all these for billing ? Finding no option to delete them ? – GLK
yep, they are all billable items. You can use aws cloudwatch delete-alarms --region us-east-2 --alarm-names ... to delete them. See here for details. – jellycsc
@jellycsc - thanks again for your help. meanwhile I disabled Autoscaling of tables using DynamoDB and all of the TargetTracking Alarms were automatically gone, rest of the Alarms I am deleting using your script. If you like you can send it as an answer so that I can upvote and accept it. – GLK
Np. I'm glad I can help. – jellycsc

To view the alarm names of all the billable CW alarms in the us-east-2 region, use the following AWS CLI command:

aws cloudwatch describe-alarms --query 'MetricAlarms[*].[AlarmName]' --region us-east-2

You can delete them using:

aws cloudwatch delete-alarms --region us-east-2 --alarm-names ...
