When you use Prometheus Service of Application Real-Time Monitoring Service (ARMS), you are charged based on the number of reported data entries 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.
The following tables describe the basic metrics of Kubernetes clusters that are supported by Prometheus Service.
