Datasource With Cloudwatch

I am using Cloudwatch as a Data Source and added the access key, secret to the config area, I am getting http 2.0/500 error when i test, There is an user named grafana configured on the amazons cloud side with the role CloudWatchEventsReadOnlyAccess

is there something i am missing here, This is a hosted grafana instance

For cloudwatch you need to add


to you aws role / iam user

Ok thanks will try it
