A performance management system (PM) manages a large number of NE network element devices, and performance data collected every day is also in a massive level, so that a user can customize a plurality of monitoring windows and a large number of report timing tasks in order to monitor, count and analyze the index performance of a network. In consideration of style and visual effect, a fusion Chart component is introduced into the PM at the initial development stage, and the use requirements of operation and maintenance personnel under various service scenes can be met through rapid configuration and flexible extension of programs by the foreground. Since the PM relates to a plurality of background scheduling tasks, how to directly generate a result file with the same display effect as a foreground interface at a server side becomes one of the research problems.
The PM System is generally used for monitoring the performance of a communication Network, and provides visual display of the overall performance and development trend of a telecommunication operator Network by collecting, analyzing, warehousing, summarizing and displaying performance data of an EMS (Element Management System) System and an NE (Network Element equipment) Network Element. In the PM system, a variety of 20 chart styles such as line charts, bar chart, pie charts, area charts, bubble charts, instrument panels, and the like are used in a great number.

The embodiment provides a method for exporting background image data, which is a method for exporting background images by using a wkhtmltox plug-in, so that result differences caused by different drawing mechanisms are effectively avoided, a file generated by a timing task can also keep a 'what you see is what you get' display effect with a foreground interface, and consistency of export effects of a foreground and a background is ensured. The method for exporting the background picture by using the wkhtmltox plug-in can be well suitable for the expansion, does not need to add extra codes even if more graphic styles are customized subsequently, and shows good universality and adaptability.
As a more specific embodiment, the method provided in this embodiment includes:
(1) and installing a wkhtmltox tool on the preset server.
Specifically, the wkhtmltox toolkit is downloaded to the official, and is installed on a preset server. Note that different operating systems need to download different installation packages. And creating a path which can be accessed by the web on the server as a specified path (access path) for storing the html file temporarily generated by the program.
(2) Decomposing each graphic object on the interface, acquiring a respective data source, and acquiring a presentation form of each graphic object, such as a graphic style, a length-width ratio and the like.
(3) And a background program (a program on a preset server) generates a temporary static html page (static page) under a specified path, only one graph is rendered in the page, and the style and the data source of the graph are consistent with the foreground interface of the system.
(4) A cmd command string is generated to be executed.
(5) A new process call cmd command is initiated.
(6) And generating a export picture under the specified path, and deleting the temporary html page.
(7) And (5) repeating the steps (3) to (6) for multiple times until all images in the interface are exported.
(8) And generating an Excel file, and writing all images exported under the specified path into the Excel file.
Likewise, pdf files or other file formats may be generated in the same manner.
Or, exporting the image object in the page to be exported according to the following method, specifically comprising:
(1) downloading the wkhtmltox toolkit to an official party and installing the wkhtmltox toolkit on a server (a preset server). Note that different operating systems need to download different installation packages.
(2) A path accessible to the web (page to be exported) is created on the server for storing the html file (first file) temporarily generated by the program.
(3) A specific export operation is started. Assuming that there is a report timing task, the foreground (to-be-exported page) previews the result as shown in fig. 2. The report result generated by the timing task of the background (preset server) will also be consistent with the effect of fig. 2. Each graphic component on the circular interface records its style, size (graphic format information) and data source.
(4) And generating a temporary html file. And (4) aiming at each graph to be exported, and individually rendering the graph in one static page by using the data source and the style acquired in the step (3). The page is automatically generated by a program, stored below a temporary path created in advance and named as a specific elementary +. html format.
(5) And generating a command character string used by the wkhtmltox tool for exporting the pictures, wherein the command comprises parameters such as exporting formats, storage paths, the length and width of the pictures, whether to delay rendering and the like, and exporting the pictures rendered in the static page.
(6) And enabling the new process to execute (5) the command generated in the step.
(7) And circularly exporting each picture until all the pictures are exported, and integrating the pictures into the Excel file according to the sequence on the page. As shown in fig. 3, it can be seen that, by the method for exporting background image data provided by this embodiment, the file exported by the preset server in fig. 3 well maintains consistency with the page to be exported in fig. 2.
(8) And after the Excel file is successfully generated, deleting all html files under the temporary path.
The method provided by the embodiment enables the derivation process of various background graphic styles to be normalized. Because various graph styles such as line graphs, column graphs, pie graphs, area graphs and the like are involved in the system, if the system is realized by using a class library similar to Jfreechart, each graph needs to write a corresponding derivation program, and the code is complicated and the realization is complex. By using the wkhtmltox tool, the graphics rendered on the page can be directly exported in a screen capture-like mode, each graphic style does not need to be processed independently, development cost is saved, export of all the graphic styles can be completely realized by fewer code lines, and export efficiency is greatly improved.
The consistency of the leading-out effect of the foreground and the background is ensured. The fusionChart component provides good visual perception for users, but background export is not supported, and the background export realized by using other library interfaces cannot be completely consistent with interface display, and the display styles are quite different. By using the method for exporting the background picture by using the wkhtmltox plug-in, the result difference caused by different drawing mechanisms is effectively avoided, and the file generated by the timing task can also keep the 'what you see is what you get' display effect with the foreground interface.
The method can be well adapted to the customized expansion of the chart in the subsequent system. The PM system is solidified to realize various common charts and cover most of service scenes, but in order to meet different service requirements of overseas operators, an expansion interface is reserved in the system to support the customization and expansion of the charts. The method for exporting the background picture by using the wkhtmltox plug-in can be well suitable for the expansion, does not need to add extra codes even if more graphic styles are customized subsequently, and shows good universality and adaptability.
Fig. 4 shows a block diagram of an apparatus for implementing background image data export according to an embodiment of the present invention, and referring to fig. 4, the apparatus for implementing background image data export according to the embodiment includes a creation module 401, a storage module 402, and an export module 403, wherein,
