After enabling the CloudWatch integration, you might see a metric reporting from a node named "N/A". Some AWS crawlers send an aggregate metric in addition to the per-node metrics.
If you'd like to remove the "N/A" tagged metrics, we can enable a feature that will filter out all AWS aggregate metrics. Be advised that monitors and graphs set up for AWS metrics using sum values may be affected after we enable filtering.
Contact support to enable filtering and check if any of your monitors will be affected.
