If the host is not registered with AWS integration, there may be an error in the settings, etc.

Please check the following items.

Check the IAM role for AWS integration

• Please check that the necessary policies for working with CloudWatch are attached to the IAM role.
  • The IAM policies required vary depending on the AWS product.
• For some products, if you want to set up AWS integration that only targets that product, you will need the CloudWatchReadOnlyAccess permission in addition to the required policies/actions.
  • The products with *1 in the product name of Policies required for integration are the target.

Check that the settings for filter by tags are correct

• when filtering by tags, the tags must also be set appropriately on the AWS product side.
• Additional policies are required to filter tags using ElastiCache, SQS, and Step Functions.
  • Please refer Grant permissions for tag retrieval.

If the above is checked and no problems are found

Please check the following points.

• Check that the IAM role ARN and external ID match the AWS settings.
• Check that the region set in the AWS integration matches the actual region.
• Check the box next to the AWS product you want to use.
• Check the metrics for the target instance are being recorded on CloudWatch.
  • If the metric is not recorded on CloudWatch, it will not be integrated to Mackerel either.
