I’m using Grafana version v10.0.3 and I’m trying to use nested variables but failing. I’m using AWS CloudWatch as a datasource and I want to show a list of RDS instances based on the regions that are selected. I can get this to work if I select a single region but whenever I select multiple regions it won’t show and instances. At the moment I have the following variables set up:
- A query that uses CloudWatch as its datasource and the query type is ‘Regions’. The ‘Multi-Value’ option in ’selecting options’ is also selected.
- A query that uses the following:
Data Source: CloudWatch
Query type: ‘Dimension Values’.
Region: ‘Template Variables > $region’
Dimension Key: DBInstanceIdentifier
As an example, if I selected us-east-1 and eu-west-1 regions, I would expect to get 6 results:
Can anyone help me out with this?
