Transaction indicator monitoring methods, apparatuses, and devices

A non-transitory, computer-readable medium storing one or more instructions that, when executed by a computer system, cause the computer system to perform one or more operations comprising:

• storing transaction data of a transaction that is used to perform the transaction, wherein the transaction data comprises a plurality of transaction dimensions, wherein each of the plurality of transaction dimensions includes fields that are used to reflect payment and risk control characteristics of the transaction, and wherein the each of the plurality of transaction dimensions includes one or more transaction dimension values;
• specifying a plurality of transaction indicators including a first transaction indicator and, for each of the plurality of transaction indicators including the first transaction indicator, multiple sets of transaction dimension values to be monitored, wherein a transaction indicator is used to reflect statistical characteristics of the transaction data;
• obtaining, based on a user specified time range, monitoring transaction data associated with a specified plurality of transaction indicators including the first transaction indicator, wherein sampling sequences of the first transaction indicator are obtained under the multiple sets of transaction dimension values of the monitoring transaction data respectively, wherein each set of transaction dimension values corresponds to one sampling sequence, respectively, wherein a first sampling sequence comprises values of the first transaction indicator at a predetermined quantity of sampling points under a first set of transaction dimension values, and a value of the first transaction indicator at a target sampling point in the first sampling sequence is a first actual value;
• calculating, for the first sampling sequence, an estimated value, wherein the estimated value is an estimated value of the first transaction indicator at the target sampling point in the first sampling sequence based on the first sampling sequence;
• calculating a target sampling point difference between the first actual value and the estimated value;
• determining the value of the first transaction indicator at the target sampling point under the first set of transaction dimension values corresponding to the first sampling sequence is abnormal when the target sampling point difference exceeds an abnormality threshold, wherein the abnormality threshold is corresponding to the first set of transaction dimension values;
• and
• displaying an abnormality prompt, wherein the abnormality prompt includes a value of an abnormal transaction indicator and a corresponding set of transaction dimension values, and wherein the set of transaction dimension values indicates a cause for the abnormality.

A computer-implemented system, comprising:

• a transaction server and
• one or more computer memory devices interoperably coupled with the transaction server and having tangible, non-transitory, machine-readable media storing a first set of one or more instructions corresponding to the transaction server that, when the first set of one or more instructions are executed by the transaction server, cause the transaction server to perform one or more operations, comprising:
• storing transaction data of a transaction in the transaction server used by a transaction client device to perform the transaction, wherein the transaction data comprises a plurality of transaction dimensions, wherein each of the plurality of transaction dimensions includes fields that are used to reflect payment and risk control characteristics of the transaction, and wherein the each of the plurality of transaction dimensions includes one or more transaction dimension values;
• and
• a monitoring device and one or more computer memory devices interoperably coupled with the monitoring device and having tangible, non-transitory, machine-readable media storing a second set of one or more instructions corresponding to the monitoring device that, when the second set of one or more instructions are executed by the monitoring device, cause the monitoring device to perform one or more operations, comprising:
• specifying a plurality of transaction indicators including a first transaction indicator and, for each of the plurality of transaction indicators including the first transaction indicator, multiple sets of transaction dimension values to be monitored, wherein a transaction indicator is used to reflect statistical characteristics of the transaction data;
• obtaining, based on a user specified time range, monitoring transaction data associated with a specified plurality of transaction indicators including the first transaction indicator, wherein sampling sequences of the first transaction indicator are obtained under the multiple sets of transaction dimension values of the monitoring transaction data respectively, wherein each set of transaction dimension values corresponds to one sampling sequence, respectively, wherein a first sampling sequence comprises values of the first transaction indicator at a predetermined quantity of sampling points under a first set of transaction dimension values, and a value of the first transaction indicator at a target sampling point in the first sampling sequence is a first actual value;
• calculating, for the first sampling sequence, an estimated value, wherein the estimated value is an estimated value of the first transaction indicator at the target sampling point in the first sampling sequence based on the first sampling sequence;
• calculating a target sampling point difference between the first actual value and the estimated value;
• determining, for the first sampling sequence the value of the first transaction indicator at the target sampling point under the first set of transaction dimension values corresponding to the first sampling sequence is abnormal when the target sampling point difference exceeds an abnormality threshold, wherein the abnormality threshold is corresponding to the first set of transaction dimension values;
• and
• displaying an abnormality prompt, wherein the abnormality prompt includes a value of an abnormal transaction indicator and a corresponding set of transaction dimension values, and wherein the set of transaction dimension values indicates a cause for the abnormality.
