Description

  The present invention relates to an apparatus, a method, and a program for monitoring a Web server.

  2. Description of the Related Art Conventionally, a system that provides a Web service on the Internet attempts to distribute the processing load by moving a plurality of Web servers according to the number of users who use the service at the same time. The plurality of Web servers need to provide the same Web page in response to a request from the user terminal. However, a normal response may not be obtained from a specific Web server due to a hardware failure or communication failure of the server, or a release of page data release to the Web server. Therefore, the system administrator periodically compares and monitors whether or not the response from each Web server is normal.

  By the way, when an administrator monitors a Web server, visual monitoring is often performed by comparing and displaying a response when the same request is transmitted to each Web server on a monitoring terminal. In order to reduce the load of this monitoring work, for example, in Patent Document 1, the monitoring target server is monitored by searching whether there is a character string registered in advance in the HTML document of the monitoring target server. An automated system has been proposed.

  Here, since the image 30 of the web page screen to be monitored is different from the image of the surrounding web page screen, the display frame is emphasized. In addition, the advertisement column that is likely to be different in display is replaced with the same display “advertisement” in all images of the Web page screen.

  As described above, according to the present embodiment, the monitoring apparatus 1 performs rendering processing of the Web page to be monitored, and generates one piece of monitoring image data. Therefore, the monitoring terminal can display a plurality of Web page screens by only displaying one piece of monitoring image data, and can suppress the processing load. The monitoring device 1 is a client terminal similar to the monitoring terminal 3 and other general user terminals, and thus has a rendering function equivalent to a terminal used by general users. Therefore, the administrator can monitor with high accuracy using an image equivalent to a Web page screen that is viewed by a general user.

  In addition, when there is a portion of the page data whose display changes every time a browsing request is made in the advertisement column or the like, the monitoring device 1 replaces this portion with a predetermined display and generates monitoring image data. Therefore, when comparing a plurality of Web page screens, the administrator can easily determine a portion that is not abnormal even if the display is different, so that it is possible to reduce the determination error of the administrator and improve the monitoring accuracy. .

  Moreover, the monitoring apparatus 1 compares each page image data, and highlights the page image data different from many other images. Therefore, since the administrator can easily find the highlighted web page screen, it is possible to easily detect the monitoring target web server that provides web page screens different from many other screens.

  In addition, the monitoring apparatus 1 generates monitoring image data after uniformly trimming all the page image data so that different portions of the page image data are displayed. Therefore, since the administrator can easily find a place where there is a possibility of abnormality, it can be expected that the detection omission is reduced and the monitoring accuracy is improved.
