Introduction to Pay-as-you-go
Last updated: 2025-12-11 16:59:09
Application Performance Management (APM) supports the pay-as-you-go (postpaid) mode, allowing you to use first and pay later. Fees are charged at the time of settlement based on the reporting status of connected applications.
Billing Cycle
Charges are calculated on an hourly basis. The total consumption for the previous hour will be calculated and deducted within the next 2 to 4 hours.
Pricing
Fee Calculation
Total cost = Reported link fees + Link storage cost
Reported link fees = Report quantity (million) × Unit price reported on the link
Link storage cost = Reporting quantity (millions) × Storage duration (days) × Unit price of link storage
Billable Items and Free Tier
Note:
APM offers a 15-day trial period for new users with a report limit of 100 million Spans and a fixed storage duration of 7 day. If the quota is exceeded, you can manually upgrade to the paid version. Different regions have different billing rates. To switch to the paid version, see Purchase Methods.
Billable Items | Unit Price | Free Tier |
Link Reporting | 0.02 USD/Million Spans | 1 million Spans/day |
Trace retention | 0.012 USD/Million Spans × Days | 1 million Spans/day |
Note:
Definitions of the Trace and Span:
Trace: A call chain represents the execution process of a transaction or process in a distributed system. It is a Directed Acyclic Graph (DAG) composed of multiple spans, where each Span represents a named and timed continuous execution segment in the call chain.
Span: A Span represents a logical execution unit in the system with a start time and execution duration. Within the same Trace, Spans establish logical causal relationships through nesting or sequential arrangement.
Billing Examples
Assuming a user submits 20 million requests (200 million spans) daily with a retention period of 7 days, the required fees per day are as follows:
Link reporting daily cost = (200 million Spans - 1 Free tier) × 0.02 = 3.98 USD/Day
Daily cost for Trace retaining = (200 million Spans - 1 Free tier) × 0.012 × 7 days = 16.716 USD/Day (the retaining fee after six consecutive days of reporting)
Total cost = Reporting volume cost + Trace retaining duration cost = 3.98 + 16.716 = 20.696 USD/Day.
