Note
  • The ingestion data volume is the data stored in the ARMS platform after processing, such as cleaning, aggregation, conversion, and analysis, not the raw traffic reported by ARMS agents or open-source agents/SDKs.

  • This billing model includes a free storage period for each data type. These storage periods are fixed and cannot be modified.

  • The free tier is granted at the Alibaba Cloud account level upon activating a paid plan, and is shared across different applications/instances of sub-services under the account. The monthly free tier for Application Monitoring/Managed Service for OpenTelemetry can be used across regions and is deducted based on the billing order of the region or application; the first item billed receives the deduction.

  • Starting from 00:00 on July 1, 2024, Managed Service for OpenTelemetry bills for its default performance statistics metrics. Custom metrics are billed based on their ingestion data volume. All metrics share the 25 GB monthly free tier of Managed Service for OpenTelemetry.

  • The free tiers for metrics and traces in Application Monitoring/Managed Service for OpenTelemetry cannot be transferred or combined. For example, if you ingest 40 GB of trace data and 5 GB of metric data in a single month, you will be billed for 15 GB of trace data, and you forfeit the remaining free tier for metrics.

  • Profiling data consists of files generated by Continuous Profiling and Application Diagnosis, which include memory snapshots, performance analysis flame graphs, and thread status and call stack information from thread analysis.

  • For Application Monitoring/Managed Service for OpenTelemetry, the minimum daily usage for each billable data type per application is 0.1 GB. For example, if an application uses 20 MB of metrics, 10 MB of traces, and 0 MB of profiling data in a day, it is billed for 0.1 GB of metrics, 0.1 GB of traces, and 0 GB of profiling data.

Note
  • Currently, only trace data can be archived.

  • To enable or disable archive storage: In the Managed Service for OpenTelemetry console, go to the Storage Retention Period Configuration section on the System Configuration > Cluster Configuration page to choose an archive period or disable it as needed. Archive storage settings apply per region.

  • Supported archive periods: 60, 90, and 180 days.

Billing cycle

At 00:00 each day, Application Real-Time Monitoring Service (ARMS) calculates the previous day's resource consumption. Bills are typically issued by 08:00, and the fee is then automatically deducted from your account balance if it is sufficient. You can view your bills in the Expenses and Costs console and check your resource usage in the Managed Service for OpenTelemetry console. For more information, see Resource usage and bills.

How to activate

Go to the buy page of Managed Service for OpenTelemetry and activate the service as prompted.
