Billable items
Savings plans are not supported. To use a savings plan, submit a ticket.
Billable item | Retention period (days) | Free quota | Unit price (Alibaba Cloud) |
Metric | 90 | 50 GB |

Observable data is collected by the self-developed ARMS agent or open source agents or SDKs, cleansed, aggregated, transformed, analyzed, and stored in ARMS. The amount of observable data is not equal to the traffic.
You are charged based on the amount of observable data. After data is written to ARMS, you are entitled to free storage. The storage duration depends on the data type, and cannot be modified.
If you use an Alibaba Cloud account to purchase an ARMS sub-service, the sub-service provides a free quota for the account. The free quota is shared among the applications or instances that belong to the account. Monthly free quotas cannot be used across regions. Assume that you use the ARMS service for the first time in the China (Hangzhou) region. You can use monthly free quotas only in the China (Hangzhou) region.
Profiling data is generated when you use the continuous profiling and application diagnostics features of Application Monitoring. Profiling data includes memory snapshots, flame graphs of performance analysis, and thread status and call stack information of thread analysis.
For Application Monitoring and Managed Service for OpenTelemetry, the minimum billing unit of each billable item for an application is 0.1 GB per day. Assume that an application is monitored in Application Monitoring on a day. 20 MB of metric data, 10 MB of trace data, and 0 MB of profiling data are collected. You are charged for 0.1 GB of metric data, 0.1 GB of trace data, and 0 GB of profiling data.
Billing cycle
The billing cycle of ARMS is one day. ARMS generates the bills of the previous day at 00:00 every day. Generally, bills are generated before 08:00. If your Alibaba Cloud account has sufficient balance, the system deducts fees from the balance. You can view bills in the Expenses and Costs console and view the observable data volume in the ARMS console. For more information, see Bills and resource usage.
