Description

  The present invention relates to a terminal, 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.

  However, even with the system of Patent Document 1, it is difficult to accurately detect an abnormality in the actual display state of a Web page. For example, it is often impossible to determine whether a correct image is displayed on the Web page screen by comparing character strings, and portions where the display of advertisement columns and the like are not constant are abnormal even if normal. There is a risk of being judged.

  Therefore, it is important to visually confirm the state in which the Web page screen that the user sees is actually displayed in order to improve the monitoring accuracy of the Web server. However, since the correct display state is unknown only by comparing Web page screens that are responses from a plurality of Web servers, the administrator may not be able to determine correctly.

  An object of the present invention is to provide a monitoring terminal, a method, and a program that allow an administrator to accurately detect an abnormality in a Web page screen provided by a Web server to be monitored.
