Basic metrics of containers and cloud services that are supported by Managed Service for Prometheus - Application Real-Time Monitoring Service

When you use Alibaba Cloud Managed Service for Prometheus, you are charged based on the number of reported data samples on billable metrics. The metrics are classified into basic metrics and custom metrics. Basic metrics are free of charge. You are charged for custom metrics starting from January 6, 2020.
