Number of successes: Returning a successful result is considered a success;

Number of failures: Returning failure results and response timeout are all considered failures;

The total number of requests = the number of successes in the previous stage, for example, the total number of downlinks = the number of successful remote control initiations;

The data filtering rules from the ods layer to the dwd layer are shown in Table 3, where,

Link stage: from when the vehicle and the computer initiate a request to when the request returns the result, it is a complete link, called the full link, which includes initiation, downlink, Tbox execution, uplink, and full link (when the vehicle and the computer are not online, the Including the vehicle-machine wake-up phase, please refer to the complete business link diagram above).

Microservice type: Data of different links are stored in different microservices.

Number retrieval logic: Define the number retrieval rules, such as the number of initiations. If the microservice log satisfies url=control andresponseParams=null and deduplication, it is a hit rule. For the data in Table 3, for example, the link stage is 'initiate', the 'microservice type' is tsp-app-log, and the fetching logic is url=control and responseParams=nulland to remove duplicates, that is, from tsp-app-log In the microservice, the data in the log that contains control and responseParams=null is taken to remove duplicate data, which is the initiation phase, and is counted as one initiation.

The data is calculated from the dwd layer to the dws layer using indicators. The atomic indicators that affect it include the number of successes, the total number of initiations, the response time, and the error type. Taking the indicator for calculating the success stage of tbox execution as an example, the tbox execution feedback in the dwd layer is successful. The data summary is the number of successful executions of tbox. The total number of executions of tbox is the number of successful executions of the previous stage of tbox execution, which is the number of successful downstream feedbacks. The success rate of tbox execution is the number of successful executions of tbox/the total number of executions of tbox*100%; Taking the calculation of indicators in the successful tbox execution phase as an example, the data of successful tbox execution feedback in the dwd layer can obtain the end time of the tbox execution phase. Successful downstream feedback can obtain the start time of the tbox execution phase. The tbox execution response time = the tbox execution phase. End time - the start time of the tbox execution phase; taking the indicators of the tbox execution failure phase as an example, the tbox execution phase error type can be analyzed based on the err_code and err_message of the tbox execution failure data in the dwd layer.
