Identify AccountID on alert when using CloudWatch Cross Account

[hectorruiz]

Hi everyone!
I’ve setup CloudWatch cross Account monitoring on an AWS account. On the same account I’ve hosted an ECS service with a Grafana image inside with a CloudWatch datasource. Dashboards work perfect and I’m able to see metrics from different accounts. My issue is alerting.

What I want to achieve is to send the AWS Account ID or label and the AWS region on an alert. An example of my desired alert would be the following:

[FIRING:1] TestAlert Grafana critical

Firing

Value: [no value] Labels:

alertname = TestAlert
instance = Grafana
severity = critical

Annotations:

description = descriptions
summary = summary
accountID = 12346789 # <------
AWS Region = eu-west1# <------

Is there a way to achieve this?

Thanks in advance!

Define/hardcode them as custom labels/annotations on the alert level.

There’s no way to add this dynamically?
My issue is that I want to provision alerts as dynamic as possible because some accounts are created and deleted often to do tests and then they’re cleaned up. And also I have more than 30 clients that use multiple regions.
Thanks for your time!

Yes, it can be “dynamic” if you are able to return it from CloudWatch query - can you do that?

Yes! I’m able to get regions and account IDs from a query when configuring a dashboard variable:

Your question is about alert, not about dashboard. Alert! = dashboard.
So can you get account id and region from the CloudWatch alert query?
