Definition

Service cycle: a service cycle is a calendar month.

Total minutes of service cycle: calculated based on the total number of days in the service cycle × 24 (hours) × 60 (minutes).

Error rate: the number of valid requests that cause HTTP status 500 and code "ODPS-0010000: System internalerror" responses within a period of time divided by the number of valid requests within this period of time. therefore, the error rate in this period is obtained. Repeated requests are not included in the error rate.

Service unavailability: The service unavailability time is measured based on the server error rate. If the MaxCompute server error rate exceeds 5%, the service is unavailable.

Service unavailable Time period: the statistics are collected every five minutes. If the error rate exceeds 5% within these five minutes, the service is considered unavailable for that five minutes.

Monthly service fee: the total charges paid by the customer for a single MaxCompute Project in one calendar month. If the customer pays the service fee for multiple months in one lump sum, the monthly service fee is equal to the number of months purchased.
