Application Real-Time Monitoring Service (ARMS) has introduced new billing rules. You are charged based on the observable data or enabled features. This topic describes the billing modes, billable items, and billing cycles of different sub-services.
New users of Application Real-Time Monitoring Service (ARMS) are charged based on the observable data. For users who have activated ARMS, billing can be upgraded in the ARMS console as prompted. For more information, join the DingTalk group (ID: 37120013838) to obtain technical support.
Billing modes and billable items
If you use the pay-as-you-go billing method, you are charged based on the observable data or enabled features.

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.
①Managed Service for OpenTelemetry does not charge fees for default performance metrics. For billing updates, pay attention to ARMS announcements. Fees are charged for custom metrics based on the data volume. Managed Service for OpenTelemetry provides 50 GB of traffic per month free of charge.
②You can store the basic metrics of Container Service for Kubernetes (ACK) clusters in Managed Service for Prometheus for seven days free of charge. For more information about basic metrics, see Metrics.
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.
For Managed Service for Prometheus, the minimum billing unit of an instance is 0.1 GB per day. Assume that 20 MB of metric data is collected by a Prometheus instance on a day. You are charged for 0.1 GB of metric data.
Pay-by-feature
Sub-service | Billable item | Monthly free quota | Unit price (Chinese mainland) | Rule |
Application Security | Agent | None | USD 0.015/Agent/Hour | |
Managed Service for Grafana | Number of managed workspaces |
| As low as USD 37.74/dedicated workspace/per month |
If you are charged based on the enabled features, free quotas are automatically provided for your Alibaba Cloud account.
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 Billing Management console and view resource usage in the ARMS console.
View data volume
You can query observable data only in the Chinese mainland.
You can view data volume on the Usage Statistics tab of the Overview page in the ARMS console.
Estimate fees
Estimate fees based on data volume
If you have not monitored an application in ARMS, you can connect a test application to ARMS. Then, you can view data volume on the to estimate the overall cost.
If you have applications monitored in ARMS, you can directly view data volume on the to estimate the overall cost.
Assume that you use Application Monitoring to monitor your applications. In a month, applications deployed in the China (Hangzhou) region generate 1,000 GB of observable data and applications deployed in the China (Beijing) region generate 800 GB of observable data. Considering that you have a 50-GB free quota per month, the fee of the month is calculated based on the following formula: USD 0.062 × (1,000 + 800 ‒ 50) = USD 108.5.
Estimate fees based on the business scale
You can estimate fees based on the following data models. Estimated fees are not accurate, and are for reference only.
Application Monitoring
Assume that queries per second (QPS) are 100, sampling rate is 10%, convergence is enabled for interface metrics, and profiling is disabled. Each agent collects about 2 GB of data. The following table lists the differences between previous and current prices.
Application scale | Estimated monthly data volume | Current price (pay-as-you-go) | Previous price (pay-as-you-go) | Previous price (resource plan) |
Small (50 nodes = 50 agents) | 3000 GB | USD 186/month | USD 1,490.4/month 88% costs saved | USD 776/month (76% costs saved). Two 28,800 Agent × Hour resource plans that cost USD 1,241.9 are required. |
Medium (200 nodes = 200 agents) | 12000 GB | USD 744/month | USD 5,961.6/month 88% costs saved | USD 2,328.57/month (68% costs saved). One 230,400 Agent × Hour resource plan that costs USD 3,725.71 is required. |
Large (500 nodes = 500 agents) | 30000 GB | USD 1,860/month | USD 14,904/month 88% costs saved | USD 4,657/month (60% costs saved). Two 230,400 Agent × Hour resource plans that cost USD 7,451.42 are required. |
Managed Service for OpenTelemetry
Under the new billing rules, you are charged for Managed Service for OpenTelemetry based on the volume of observable data that is written. For example, the average size of a span is 1.27 KB. 0.1 billion spans are generated each day and each span is stored for 30 days. In this case, the following table compares the daily fees calculated based on the new and previous versions of billing rules.
Business scale | Estimated daily data volume | Pay-as-you-go fee based on the new billing rules | Pay-as-you-go fee based on the previous billing rules | Cost down by |
0.1 billion spans stored for 30 days | 121 GB | USD 7.5 per day | USD 10.75 per day | 30% |
Under the new billing rules of Managed Service for OpenTelemetry, you are not separately charged the reporting fee, storage fee for traces, and storage fee for each metric.
Managed Service for Prometheus
Assume that the average size of a metric entry is 0.5 KB. The following table lists the differences between previous and current prices of Managed Service for Prometheus.
