As shown in fig. 4 to 8, the priority of the fault rule is divided into four levels: the response rate of the first stage, the success rate of the second stage, the response time of the third stage and the transaction amount of the fourth stage, and no transaction request exists. The positioning logic is divided into A type, B type, C1 type and C2 type, in the same type priority, when a plurality of alarms appear at the same time, the priority of the positioning logic is displayed according to the priority of the positioning logic, and the A type of the positioning logic is higher than the B type, the C1 type and the C2 type. The class A comprises class A1 to class A9, the class B comprises class B1 to class B3, the class A processing response rate, the success rate and the response time alarm are single-transaction component alarms, only the transaction component alarms, the class B alarms are used when the current transaction component has alarms but does not trigger class A positioning logic, the class C1 processes transaction amount and no transaction request alarms, the class A alarm and the class B alarm are used when the class A positioning logic and the class B positioning logic are not triggered, and the class C2 processes the transaction amount and the no transaction request alarms are single-transaction component alarms and are used when the class A positioning logic, the class B positioning logic and the class C1 positioning logic are not triggered.
Path analysis step (path analysis module): acquiring the incidence relation, the upper index information and the upper alarm information of the current transaction component, and filtering according to a time axis to generate an alarm path.
Positioning alarm step (positioning alarm module): judging whether the alarm path is finished or not, if so, finishing the positioning alarm and returning a positioning result, if not, judging whether the alarm of the next transaction component meets the rules or not, if not, returning to the judgment of whether the alarm path is finished or not by taking the current transaction component as a root component, if so, switching to the next transaction component, recording the alarm information and the alarm path, judging whether the next transaction component exists or not, if so, returning to the judgment of whether the alarm path is finished or not, and if not, switching to other previous transaction components of the current transaction component and returning to the judgment of whether the alarm path is finished or not.
Data storage step (data storage module): storing the related original data, positioning the result path and information.
For example, there are three transaction components, a, b, and c, where a and b are transaction associations and b and c are transaction associations. Alarm monitoring is set for A, B and C, and response rate threshold alarm and response time threshold alarm are set for A, B and C. And setting a custom fault positioning rule. A B1 fault location mode exists for A, B and C, an A1 fault location mode exists between A and B, and an A1 fault location mode exists before B and C. And (4) data processing, wherein data A triggers response rate alarm and data B and C triggers response time alarm in a certain minute. According to the fault positioning rule, the system traverses the alarm path and judges that the positioning grades are A, B, C1 and C2 in sequence. A5 and A1 are satisfied between A and B, A3 and A1 are satisfied between B and C, and at this time, no A-type location is triggered between A, B and C. A meets the fault location mode B1, B and C meet the fault location mode B3, not meet B1, only A triggers B type location at this moment. And refreshing fault positioning information, storing data into a database, and displaying and refreshing a page. At the moment, the fault location judges that the response rate of the A exceeds the threshold value, and causes the response time of the B and the C to exceed the threshold value.
