# Observability Pattern for Amazon Managed Prometheus

This module provides an automated experience around Observability for AMP (Amazon Managed Prometheus) workspaces.
It provides the following resources:

- AWS Managed Grafana Dashboard
- Cloudwatch data source to monitor AMP usage and alert metrics.

Note: The Billing widget of the dashboard requires [CloudWatch Billing Alerts](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/monitor_estimated_charges_with_cloudwatch.html) to be enabled.

- CloudWatch alarms for AMP service quotas.
