Embodiments of the present application are described below with reference to the accompanying drawings:
referring to fig. 1, an embodiment of the present application provides a method for collecting logs of a 5G core network element, where the method is applied to an operation maintenance management network element, where the operation maintenance management network element interacts with a WEB front end and a core network element respectively, and the method includes, but is not limited to, the following steps:
step S110, receiving a log collection instruction issued by a WEB front end; the log collection instruction comprises a filtering condition;
step S120, forwarding the log collection instruction to a core network element; the core network element compresses and packages the logs according to the log collection instruction, stores the packaged log compressed files into a preset catalog and uploads the storage paths to an operation maintenance management network element;
step S130, storing the storage path into a database;
step S140, receiving a downloading instruction issued by the WEB front end;
and step S150, according to a downloading instruction, the log compression file downloaded from the storage path is sent to the WEB front end.
In the embodiment of the present application, taking the distributed deployment system framework shown in fig. 2 as an example. As can be seen from fig. 2, the system framework includes a WEB front end, OAM, and several subsystems. Wherein one subsystem comprises at most one set of core network, but one subsystem may comprise a plurality of core network elements. Illustratively, subsystem 1 includes UPF and LogAgent, subsystem 2 includes SMF and LogAgent, and subsystem 3 includes AMF and LogAgent. In the working process, the WEB front end can collect the core network element logs of different systems through the page of the log collecting system module of the webpage, and send relevant notification information to the OAM through the RESTful interface of the HTTP in an event notification mode. Illustratively, the WEB front end sends a log collection instruction containing filter criteria to the OAM. Then, the OAM forwards the log collection instruction to a core network element back-end program and a corresponding log processing program LogAgent, and after receiving the log collection instruction sent by the front end, the core network element starts compressing the log, and can filter the log file according to the filtering condition sent by the WEB front end and then compress and package the log file. Illustratively, the filtering condition is that the current generated log file is compressed and packaged by tracing back the corresponding date by day or by week. When the WEB front end sends a log collection instruction, an activated interface is also sent at regular time to detect whether the background is used for compressing and packaging FILEs, after the background program of the core network is packaged, the completion condition of the log can be notified through a report progress mode, a log agent program uploads the generated FILE to a designated directory FILE through an ftp mode, and meanwhile the FILE generated before is cleared, so that occupation of a hard disk space is avoided. The OAM stores the log paths of each core network in a database DB, and stores the mapping relation between the stored paths and the network elements of the core network in the database. After the OAM finishes data storage, the WEB front end can send a downloading instruction to the OAM in an http mode, so that the OAM can determine a core network element corresponding to the downloading instruction, determine a corresponding storage path according to the core network element and a mapping relation, and then compress a file from a log downloaded in the storage path. Specifically, the download instruction sent by the WEB front end includes download interface information, and the OAM transmits the log compression packet file of the core network to the WEB front end by going to the designated path through the nginx reverse proxy server according to the download interface information. The WEB front end can display the downloading progress through a progress bar.
In some embodiments, as shown in fig. 3, in the process of collecting log data by a core network element, when a WEB issues a log collection instruction of the core network element, the OAM forwards the instruction to the core network element side for processing, in this process, the OAM forwards the log data to perform a relevant verification on the data sent by the front end, and the OAM security management mechanism performs a relevant determination on user authority in the OAM, if the current user is a super user, for example, an administrator account or an authorized user, according to the user authority, the authority is available for executing the log collection instruction of the core network element, after the core network element side receives the log collection instruction of the authorized user, the log to be compressed is processed according to a filtering condition sent by the front end, for example, according to time period information and the like required to be compressed by a log file, and meanwhile, the WEB front end can also issue log grade information through an HTTP interface, so as to control the generation grade of the log on the core network element side through the log grade information. Under the default condition, the log grade is ERROR, if the log is required to be tracked and debugged, the log grade is generated into a DEBUG mode through an HTTP interface of the WEB front end, then the logs of the core network are collected, and the interface related to the logs of the core network is transmitted and controlled through the WEB front end, so that the collection requirement of the logs of the core network according to the requirement is realized.
In some embodiments, as shown in fig. 4, the process of the OAM forwarding the log collection instruction of the WEB front end to the core network element side for processing includes, but is not limited to, the following steps:
in step S410, the OAM sends, according to the correspondence between the system and the network element stored in the database, the content related to the log collection instruction sent from the WEB front end to the related network element of the corresponding row through json data. Wherein, a system can have a core network element therein, and a plurality of core network elements can also exist.
In step S420, after receiving the log collection instruction sent by the OAM, the network element parses the json data, for example, parses the json data to obtain the filtering condition including key information such as time parameters, and then packages and compresses the network element log according to the key parameters, where the compression mode is typically a tar command. JSON (JavaScriptObject Notation) is a lightweight data exchange format that stores and presents data in a text format that is completely independent of the programming language.
In step S430, after the log package is completed, the network element program of the core network sends a notification to the log agent program, and the log agent program uploads the compressed log package to the designated path by means of FTP.
Step S440, the Logagent program uploads the compressed package and simultaneously sends the appointed log file storage path to the OAM program through an HTTP interface mode, the OAM program writes the received storage path of the compressed log file of the core network into a database, and meanwhile, the mapping relation between the system and each network element log file is stored in a large database.
In some embodiments, when the core network compresses the log file, the WEB front end may also view the processing progress of the core network on the log file in real time. Specifically, as shown in fig. 5, the present embodiment may include, but is not limited to, the following steps:
in step S510, the WEB front end may detect whether the compression of the network element log on the network element side in different systems is completed in a timer manner. Because the compressed key data has one time period, the size of the compressed file generated by different time periods is quite obvious. The embodiment can judge the compression progress according to the size of the compression file.
Step S520, if the core network element of the system has completed compressing the log file, when the activated interface sent by the WEB front end is received, the size of the compressed file is actively reported, and the OAM writes the file size and the association relation of the corresponding system, network element and the like into the database.
In step S530, the WEB terminal receives the information related to the log file compressed by the core network of the network element side forwarded by the OAM, and triggers the file download interface of the WEB front end.
In step S540, the WEB front end may compress log file instructions for the network elements of the download core network issued by different systems, or issue download instructions for a certain system, where the OAM returns the log paths of the core network elements under different systems to the WEB front end.
Step S550, the WEB front end starts to download a log of a network element corresponding to a certain system according to the path returned by the OAM, the related file size information and the related information of the network element of the system, or downloads the log concurrently, and at the same time, the WEB front end may also display the progress of downloading the log file of the corresponding network element by using a progress bar.
In some embodiments, as shown in fig. 6, when the WEB issues a core network log downloading instruction, the OAM searches a database with a system and a network element corresponding to the WEB front end as keywords, and returns related information including the system, the network element, the log name and the size of the log file to the WEB front end after finding a matching record, where the WEB front end downloads compressed log files of the network elements under different systems according to the size of the log file in a progress bar display manner.
In summary, the method for collecting the logs of the 5G core network element in the embodiment of the invention can realize the separation of front and rear ends, thereby being convenient for operation and maintenance personnel to find problems in time, being capable of better assisting research and development personnel to locate the problems, having very high universality and mobility through an HTTP interaction mode, being capable of realizing security by using an HTTP2 mode for encryption transmission, and being capable of realizing the authorization of different users through a security mechanism in OAM. In addition, the method of the embodiment can support the downloading of the core network logs of the distributed system and the centralized system, can conveniently and efficiently realize the centralized control of the logs of the system by controlling the database through the OAM program background, has universality and can realize encryption transmission by downloading through the HTTP mode and only needing to configure certificates and private keys.
