Billing

Currently, APM has two editions: free and enterprise. If you switch from the free edition to the enterprise edition, you will be billed pay-per-use. If you have purchased a preferential package, the Agents you use will first be deducted from it. Any excess Agents will be billed pay-per-use. For details, see Billing Overview.

Agents will be billed based on one hour, rounded up to the nearest one hour.
The billing unit is one enterprise-edition Agent.
You will be billed based on this unit during pay-per-use or package billing.

Renewal Details

Preferential packages need to be prepaid. When your package expires or is about to expire, renew it in time. If you do not renew it in time, APM functions may be affected.
