Abstract

A computing system may determine that a change has occurred in a software application or a document object model associated with a software application. The computing system may obtain a current copy of a document object model (DOM) associated with the application and a current screenshot of a screen displaying the application (e.g., in response to determining that the change in the DOM has occurred). If the current copy of the DOM is determined to be similar to the screenshot, the computing system may save storage space by storing the current copy of the DOM and discarding the screenshot. The computing system may store the current copy of the DOM in a memory buffer. The computing system may send the DOM copies or screenshots stored in the memory buffer to the monitoring system, for example, if an error in the application is detected.

Claims20

Dependent claims

A system that uses data targeted to an error to generate error reports, the system comprising:

storage circuitry comprising a memory buffer configured to store document object model (DOM) copies corresponding to a web application;
and
control circuitry that performs operations comprising:
determining that a change has occurred in a DOM, wherein the DOM comprises a tree structure comprising nodes representative of portions of a web page, and wherein the change indicates that input from a user has caused the DOM to change;
in response to determining that the change in the DOM has occurred, obtaining a current copy of the DOM and a current screenshot of a screen displaying the web application, wherein the current screenshot comprises a first image of an interface where the web application is rendered for display;
generating, based on the current copy of the DOM, an estimated rendering of the web application;
determining whether the current screenshot matches the current copy of the DOM;
determining that the memory buffer stores more than a threshold number of DOM copies;
in response to determining that the memory buffer stores more than the threshold number of DOM copies and that the current screenshot matches the current copy of the DOM, replacing an oldest DOM copy of a plurality of DOM copies, stored in the memory buffer, with the current copy of the DOM, wherein each DOM copy of the plurality of DOM copies corresponds to a previous change made to the DOM;
determining that an error has occurred, wherein the error is associated with the web application;
and
in response to determining that the error has occurred, sending the plurality of DOM copies to a monitoring system.

9 more elements

A method comprising:

monitoring a document object model (DOM) corresponding to a web application, wherein the DOM comprises a tree structure representative of a web page;
determining that a change has occurred in the DOM;
in response to determining that the change has occurred in the DOM, obtaining a current copy of the DOM;
determining that a stored number of DOM copies meets a threshold;
in response to determining that the stored number of DOM copies meets the threshold, replacing an oldest DOM copy of a first plurality of DOM copies, stored in a memory buffer, with the current copy of the DOM, wherein each DOM copy of the first plurality of DOM copies corresponds to a previous change made to the DOM;
detecting an error within the web application;
and
in response to detecting the error, sending the first plurality of DOM copies to a monitoring system.

5 more elements

One or more non-transitory, computer-readable storage media comprising instructions that, when executed by one or more processors, causes operations comprising:

monitoring a document object model (DOM) corresponding to a web application, wherein the DOM comprises a tree structure representative of a web page;
determining that a change has occurred in the DOM;
in response to determining that the change has occurred in the DOM, obtaining a current copy of the DOM;
determining that a stored number of DOM copies meets a threshold;
in response to determining that the stored number of DOM copies meets the threshold, replacing an oldest DOM copy of a first plurality of DOM copies, stored in a memory buffer, with the current copy of the DOM, wherein each DOM copy of the first plurality of DOM copies corresponds to a previous change made to the DOM;
detecting an error within the web application;
and
in response to detecting the error, sending the first plurality of DOM copies to a monitoring system.
