Support for multiple roles(role_arn) to achieve cross-account metrics is not working.

[JogiInnov]

When using variable for role_arn no metrics are coming.

Below are the details:

1.) prometheus config:

• job_name: 'sample_redshift'
  metrics_path: '/scrape'
  ec2_sd_configs:
  • region: us-east-2
    static_configs:
  • targets: ['arn:aws:iam::xxxxxxxxxxxx:role/cloudwatch-role']
    relabel_configs:
  • source_labels: [address]
    target_label: __param_targetrole
  • target_label: address
    replacement: 'localhost:9042'

2.) Target Url:
curl 'http://localhost:9042/metrics?targetrole=arn%3Aaws%3Aiam%3A%3Axxxxxxxxxxxxxx%3Arole%2Fcloudwatch-role&region=us-east-2'

3.) Ouptut from exporter:
HELP cloudwatch_requests_total API requests made to CloudWatch
TYPE cloudwatch_requests_total counter
cloudwatch_requests_total 0

4.) sample.yml config:

tasks:

• name: redshift_cloudwatch
  default_region: us-east-2
  role_arn: [$_targetrole]
  metrics:
  • aws_namespace: AWS/Redshift
    aws_metric_name: DatabaseConnections
    aws_dimensions: [ClusterIdentifier]
    aws_statistics: [Average]

5.) from aws-cli everything is working fine when switching between the roles.

Looks like role_arn tag is not supported in the config.file
