Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a method, a device and a medium for extracting log records, which are used for extracting all log records of the same service process from a plurality of module logs.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for extracting log records according to an embodiment of the present application, and as shown in fig. 1, the method includes:
s10: a first log record for marking the start of the process and a corresponding first log time in the vehicle information management process are obtained.
S11: and acquiring second log time corresponding to a second log record for marking the start of the process in the next vehicle information management process.
In this embodiment, the vehicle information management process represents a management service for a vehicle, and the process includes data monitored during the process of the vehicle entering or exiting the parking lot or garage. It will be appreciated that each vehicle information management process begins with a log record marking the beginning of the process, and that each log record is generated with its corresponding log time. In the embodiment, different processes are distinguished by reading the log record marking the beginning of the process in the vehicle information management process, and the search range for searching the log record subsequently is determined by the log time.
S12: a feature value is extracted from the first log record.
In step S12, the feature value is important information necessary for vehicle information management, and may be one or a plurality of information. In the implementation, the information can be the license plate number, the vehicle type and the like of a vehicle.
S13: in the log records whose log time is not less than the first log time and less than the second log time, the log records containing the feature value are matched and extracted.
Compared with the prior art, the method for extracting the log records has the advantage that the log records of the same service process exist in different modules, so that the log records cannot be searched. By adopting the technical scheme, according to the starting of each service processing flow, the first log record for marking the starting of the service flow exists, and each log record has the corresponding log time when being generated. According to the technical scheme, the searching range of the log record is determined by the log time of the log record marking the beginning of the process in the two service processes, and the log record containing the characteristic value in the searching range is extracted through the characteristic value of the log record, so that all the log records of the same service process are extracted.
It can be understood that due to the multi-module processing manner of the system, the log records of the same business process are distributed in multiple modules. In the above embodiment, the feature value is extracted from the first log record of one business process, and other log records are found according to the feature value. However, due to the existence of multiple modules, the eigenvalue in the first log record cannot represent all the characteristics of a vehicle, and the log records in other modules record other eigenvalues of the vehicle, so that other log records of the same business process may be missed if only the eigenvalue in the first log record is used for searching.
Therefore, on the basis of the above embodiment, in this embodiment, after the step of matching and extracting the log record containing the feature value, the method further includes:
extracting other characteristic values except the characteristic value from the matched log records containing the characteristic value;
and matching and extracting log records containing other characteristic values in the log records with the log time not less than the first log time and less than the second log time.
For ease of understanding, the present embodiment is illustrated by a specific usage scenario. For example, in the above embodiment, the log record whose feature value is the color white of the vehicle is matched and extracted from the log records whose log time is not less than the first log time and is less than the second log time. In this embodiment, other feature values are extracted from the matched log records, for example, the license plate location is kyo a, and then the log record with the license plate number of kyo a is matched and extracted from the log records with the log time not less than the first log time and less than the second log time. It is understood that this step is a step that is continuously executed, that is, other feature values are extracted from different log records, and then the search for other log records can be performed according to the other feature values. For example, the log records with the characteristic value of Beijing A at the license plate location are found out by using the characteristic value of white as the color of the vehicle, and the log records with the characteristic value of 0000 are found out by using the other characteristic value of Beijing A at the license plate location until the searching of all the log records with the log time not less than the first log time and less than the second log time is completed.
In the embodiment, other characteristic values except the characteristic value are extracted again from the matched log records, and the other log records are searched, so that other log records of the same service process are prevented from being missed due to the existence of multiple modules.
On the basis of the above-described embodiment, in the present embodiment, matching and extracting log records containing feature values, among log records whose log time is not less than the first log time and less than the second log time, includes:
reading a current log record, wherein the first current log record is the next log record of the first log record;
judging whether the log time corresponding to the current log record is less than the second log time;
if so, judging whether the current log record contains a characteristic value;
if yes, extracting the current log record, taking the next log record of the current log record as the current log record, and returning to the step of reading the current log record;
if not, the next log record of the current log record is taken as the current log record, and the step of reading the current log record is returned.
It can be understood that, when matching log records, in this embodiment, a search is performed item by item from the next log record of the first log record according to the time increasing sequence, and the log time and the feature value of the log record are determined, so as to implement matching of the log records of one process service. Of course, in other embodiments, the log records may be matched in a random order, and it can be understood that, by using the searching method provided in this embodiment, when the log time corresponding to the read current log record is not less than the second log time, the subsequent reading of the current log record may be stopped. If in other embodiments log records are not looked up in order, new decision conditions may need to be added to decide when to stop reading the current log record.
On the basis of the foregoing embodiment, in this embodiment, after the step of matching and extracting the log record containing the feature value, the method further includes:
setting a label for the extracted log record.
It can be understood that by setting the label for the extracted log record, a subsequent technician can conveniently view the log record of the same service flow. In specific implementation, a uniform label may be set for the log record of the same service flow, and different labels may be set for the log records of different service flows so as to be distinguished.
In the above embodiment, it is necessary to search for other log records by the feature value. In the present embodiment, the feature value includes a field and a field value.
Wherein, the field indicates the type of the characteristic value, and the field value indicates the specific value of the type. For example, the field is the color of the vehicle, the field value is white, and the corresponding log records are matched by the characteristic that the color of the vehicle is white.
Therefore, the characteristic value provided by the embodiment is the group pair of the field and the field value, and the log records are matched through the group pair of the field and the field value, so that the log records which are matched incorrectly due to a single value can be avoided.
On the basis of the foregoing embodiments, the present embodiment provides a field in a specific feature value, where the field includes: license plate number, vehicle color, vehicle style, vehicle in-out time and place and city where the license plate is located.
The present embodiment provides a plurality of fields, each having its corresponding field value. When a log record is generated, its characteristic values may contain one or more fields. According to the method for extracting log records described in the above embodiment, other log records are found through one feature value, and further more log records are found through other feature values in the found log records. The field of the characteristic value of the embodiment contains most characteristic information of the vehicle, which is easy to obtain, and can find out more log records when matching the log records, thereby ensuring the integrity of the log records of the same business process.
It is understood that, in order to facilitate the arrangement and storage of information, on the basis of the foregoing embodiment, in this embodiment, after the step of matching and extracting the log record containing the feature value, the method further includes:
and adding the field value in the extracted log record to a preset template, and outputting the field value to a storage device for storage.
In this embodiment, after the log records are extracted, the field values in the log records are added to a preset template, the preset template is composed of the fields in the feature values, and the field values are added to the corresponding positions of the preset template, so that the subsequent viewing and statistics of technicians are facilitated. And the preset template added with the field value is stored in the storage device, so that the data can be conveniently traced.
