Alibaba Cloud Prometheus Service Pro Edition supports the pay-as-you-go billing method. You are charged based on your resource usage. Bills are generated and fees are deducted from the balance of your Alibaba Cloud account at the end of each billing cycle. This topic describes the billing information and pay-as-you-go billable itemsof Alibaba Cloud Prometheus Service.

Billable items

You are charged for Prometheus Service based on the number of reported data samples of metrics and the storage duration of each data sample.

Note The metrics are classified into basic metrics and custom metrics. For more information, see Basic metrics. Custom metrics refer to non-basic metrics.
  • Data samples: You are not charged a data reporting fee for the data samples of basic metrics. You are charged a data reporting fee only for the data samples of custom metrics. For information about the pricing of custom metrics, see Billing information.
    The number of data samples is calculated based on the data model of open source Prometheus. A data sample includes a metric name, labels, a timestamp, and values. Data samples are organized in a time series. For example, the kube_node_status_allocatable_cpu_cores metric is used to monitor the number of CPU cores that can be allocated per node in a Kubernetes cluster. If your cluster contains three nodes, data samples are collected from the three nodes and form three time series. If each node is sampled at an interval of 15 seconds, the total number of data samples reported per minute is calculated by using the following formula: 3 × (60/15) = 12 (data samples), as shown in the following figure. fkg
  • Storage duration: All metrics can be stored for 15 days free of charge. After the free storage duration ends, you are charged a data storage fee based on the storage duration of basic metrics and custom metrics. If the storage duration exceeds 15 days, you are charged USD 0.01 for every one million data samples per day.

Billing cycle

Prometheus Service generates a bill between 13:00 to 22:00 (UTC+8) each day for the previous day based on the pay-as-you-go billing method and deducts the amount of fees on the bill from the balance of your Alibaba Cloud account.
Note Prometheus Service generates a bill for each Prometheus instance. If your account (Alibaba Cloud account or RAM user) has multiple pay-as-you-go Prometheus instances, multiple bills are generated.

Usage notes

  1. The size of a reported data sample cannot exceed 2 KB.
  2. By default, each data sample is stored for 15 days free of charge. If you want to store data for a longer duration, you can modify the Storage Days parameter on the Storage Duration tab based on your business requirements. For more information, see How do I change the storage duration of the data samples for a metric?
  3. Prometheus Service can monitor services in the Alibaba Cloud public cloud. For more information, see Supported regions.

Billing information

Chinese mainland

  • Data reporting fee: You are charged a data reporting fee for custom metrics based on the number of reported data samples per day. Fees are cumulatively calculated by using a tiered pricing model in which the unit price for a tier is lower than the unit price for the previous tier.
    Number of reported data samples per day (million) Unit price (USD/million) Daily fee (USD)
    0~50 0.126 0~6.299
    50~150 0.102 6.299~16.535
    150~300 0.087 16.535~29.528
    300~600 0.071 29.528~50.787
    600~1200 0.055 50.787~83.858
    More than 1,200 0.039 More than 83.858
  • Data storage fee: Metrics can be stored for 15 days free of charge. By default, the Storage Days parameter is set to 15 days. If you change the value of the Storage Days parameter to a duration that is longer than 15 days, you are charged USD 0.01 for every one million data samples per day.
Important The actual prices on the buy page of Prometheus Service shall prevail.

Billing example

For example, you use Prometheus Service Pro Edition in the China (Hangzhou) region. Assume that the average number of data samples reported per day is 300 million, among which 200 million belong to basic metrics and 100 million belong to custom metrics. The following items demonstrate how the total fee per day is calculated if the 300 million data samples are stored for 15 days or 90 days.
  • Total fee = Data reporting fee + Data storage fee. If the data is stored for 15 days, the total fee per day is calculated by using the following formula:[50 × 0.126 + (100 - 50) × 0.102] + 0 = USD 11.4
  • If the data is stored for 90 days, the total fee per day is calculated by using the following formula:[50 × 0.126 + (100 - 50) × 0.102] + [300 × 0.01 × (90 - 15)] = USD 236.4
Important The preceding billing example is only for reference. The actual prices on the buy page of Prometheus Service shall prevail.
