Cloudwatch Metric Insights cross account observability support

We are excited to announce support for cross-account querying in Metric Insights query builder for AWS Cloudwatch Plugin. This enables building SQL queries to monitor across multiple accounts in the same region in AWS Cloudwatch.
This feature introduces an account dropdown for selecting one or all of your source accounts and builds a query that targets them. Furthermore, results can be grouped by account ID by selecting “Account ID” in the Group By dropdown.
For more complex queries that are not covered by the options in the builder you can switch to the manual Code editor and edit the query.

To set up cross-account querying for AWS Cloudwatch Plugin, see instructions here.
