Users access web applications on remote web servers. In one example, the web applications allow users to purchase certain products or services online. However, the user may experience problems while conducting the online purchase. For example, the web application may crash every time the user selects an icon on a web page used for an online purchase. In another situation, the user may not be able to determine how to complete the online product purchase from the instructions displayed on the web page. In a different situation, the web application may prevent the user from selecting particular items. In yet another situation, the web site may slow down or crash during certain periods of time or for particular operations. These are just a few of the many problems that may arise during an online network session.
These problems can negatively effect an e-commerce business. For example, a negative user experience during the online session may cause a potential customer to give up and abort the purchase of a particular product. Even worse, the potential customer may stop visiting the enterprise web site. Accordingly, it is important to be able to monitor user experiences during commercial online sessions and identify any problems.
Systems currently exist for monitoring web sites. However, these systems do not capture all of the information necessary for reproducing a network session. For example, certain problems may arise while a user enters information into fields on a particular web page. However, some of these errors may never be sent over the network to the web server that operates the web session. Further, some of these errors may never be persisted or noticed anywhere either on the web server or on the user terminal operating the web session. Thus, certain network session problems that a user may experience can not currently be reproduced and analyzed.
The present invention addresses this and other problems associated with the prior art. The foregoing and other objects, features and advantages of the invention will become more readily apparent from the following detailed description of a preferred embodiment of the invention which proceeds with reference to the accompanying drawings.
The terminal 13 can be any device used for accessing or exchanging information with server 42 over a packet switched network 28. The terminal 13 in one example may be a Personal Computer (PC), laptop computer, wireless Personal Digital Assistant (PDA), cellular telephone, or any other wired or wireless device that can access and exchange web information with web application 43.
The server 42 is any computing system that can operate one or more web applications 43 that are accessed by different clients 14 that may use different web browsers on multiple different terminals. For simplicity, only one client 14 is shown in
A user of client 14 accesses the web application 43 on server 42. For example, using HyperText Transport Protocol (HTTP) or HTTP over Secure Sockets Layer (SSL) (HTTPS). According to different requests 30, the web application 43 sends different responses 32 back to the client 14 that may include different web pages 44, web page logic, or other data used during the web session 50. In this example, a User Interface (UI) 15 on terminal 13 is currently displaying a web page 18 provided by the web application 43. The web page 18 includes two fields 20A and 20B that prompt a user to enter a name and credit card number, respectively.
The user enters information into fields 20A and 20B and may then select an “enter” icon (not shown) that causes the information in fields 20A and 20B to be sent back to web application 43 as additional requests 30. The web application 43 may then send back other network data, such as responses 32 according to the information contained in previous requests 30. In this example, the next response 32 from web application 43 may be information confirming the completion of an online transaction that used the user information previously entered into fields 20A and 20B. In other instances, the responses 32 can include other web pages, or other information responsive to different requests 30.
Network Monitoring
The ETR system 12 includes a network session monitor 36 that captures network data 26 that may include the requests 30 and responses 32 exchanged between the client 14 and web application 43 over packet switched network 28. The ETR system 12 also includes a User Interface (UI) monitor 16 that captures user interface events 34.
performed by client 14 that include, but is not limited to, events that may only occur locally on terminal 13. Capturing both the network data 26 and UI events 34 for a network/web session 50 allow the ETR system 12 to monitor and reproduce network sessions with a higher level of granularity and reproduce and detect events that may not be discoverable with existing network monitoring systems. As a result, the ETR system 12 can provide analytics for a wider array of network session events that happen during customer online experiences.
One example of a network session monitor 36 is described in U.S. Pat. No. 6,286,030 issued Sep. 4, 2001, entitled: Systems and Methods For Recording and Visually Recreating Sessions in a Client-Server Environment; and also described in U.S. Pat. No. 6,286,098 issued Sep. 4, 2001, entitled: System and Method For Encrypting Audit Information in Network Applications, which are both herein incorporated by reference in their entirety.
The network session monitor 36 monitors the packet switched network 28 for any network data 26 that is transferred between web application 43 and client 14 over network 28 during network session 50. As described above, this network data 26 may include any information exchanged between client 14 and web application 42 during a particular network session 50. For example, the network data 26 may include web pages 44 sent from web application 43 to client 14 and information sent from client 14 back to web application 43, such as the information entered into fields 20A and 20B.
The network data 26 can also include web page logic/code that is sent by web application 43 along with the web pages 44 to the client 14. This web page logic is then executed locally on the terminal 13 by client 14. Network data 26 can also include web session data that may not necessarily include web pages 44, but alternatively includes information that is used with a previously supplied web page 44. The significance of these types of network data 26 are described in more detail below.
The network session monitor 36 may be located anywhere on the packet switched network 28 where the network data 26 for network session 50 can be captured. In one example, the network session monitor 36 may operate on the same server 42 that operates the web application 43. In another embodiment, the network session monitor 36 could operate on a separate server that might be located within the same enterprise network as server 42. In another embodiment, the network session monitor 36 is located somewhere else in packet switched network 28. In yet another embodiment, the network session monitor 36 may operate on the same terminal 13 that operates the UI event monitor 16.
Many of the events that happen during the network session 50 may not necessarily be transferred over network 28. Thus, network session monitor 36 may only capture a portion of the information that is required to thoroughly analyze the network session 50. For example, the individual key strokes or cursor selections used for entering information into fields 20A and 20B of web page 18 may never be transferred back over network 28 to the web application. Alternatively, a batch data transfer of only the completed information from web page 18 may be transferred to web application 43 over network 28. Further, the logic sent along with the web pages 44 may autonomously change the state of a web page or the state of the web session locally on terminal 13 without ever sending information back over the network 28 to web application 43. This presents a problem when trying to fully analyze a user experience during a previously occurring network session 50.
User Interface Event Monitoring
The UI event monitor 16 is used in conjunction with the network session monitor 36 to increase the visibility and recreation granularity of online user experiences. The UI event monitor 16 monitors and captures UI events 34 that interact with the network data 26 for the network session 50. The UI event monitor 16, in one example, is a Javascript application that is downloaded to the client browser 14 via a Hyper Text Markup Language (HTML) tag. Of course, other types of software instructions can also be used for implementing the UI event monitor 16.
The UI event monitor 16 operates autonomously from web application 43 and detects certain UI events 34 associated with a particular network session 50 established between the web browser client 14 and web application 43. By operating locally on terminal 13, the UI event monitor 16 can detect certain or selected events performed by client 14 on web page 18. For example, the UI event monitor 16 can detect each character entered into the fields 20A and 20B. The UI event monitor 16 can also detect when a user selects different icons displayed on the web page 18 or when the user makes selections on the web page that cause the web session to display another web page or web link or that generally change the state of the web session. Some of these UI events 34, or sequence of events, might only be detectable locally on terminal 13 and never transferred over network 28.
The local UI events 24 associated with the network session 50 are captured by the UT event monitor 16 and then automatically transferred at captured UI events 34 to a session archive 40. Similarly, the network session monitor 36 sends the captured network data 38 for the network session 50 to the same session archive 40. A session analyzer tool 52 is then used to analyze the captured network data 38 and the captured UI events 34 for the network session 50. The ETR system 12 provides the unique combination of capturing both network data 26 exchanged between client 14 and web application 43 during a web session 50 as well as capturing the UI events 34 that are entered locally by a user when interacting with the network data 26. Based on what analytics need to be preformed, the captured network data 38 and captured UI events 34 may be analyzed separately, in combination, or synchronized together to virtually replay the previous network session 50.
The UI event monitor 16 assigns session event tags 54 to the captured UI events 34. For example, the captured events may be tagged with an associated session ID value and an associated time stamp value by UI event monitor 16. The captured UI events 34 and associated session event tags 54 are then sent to the session archive 40 in
The web application 43 may provide a common application session number for different web pages and other information associated with the same network session. If it does not already exist in the captured UI event, the UI event monitor 16 can attach the application session number for the associated network session to the captured UI events. The UI event monitor 16 may then add any other time stamp or session identification information prior to sending the captured UI events 34 to the session archive 40 (
The time stamps are used for synchronizing and replaying the captured UI events 34 with the captured network data 38 (
The network session monitor 36 (
Operations 82-86 refer to the session analyzer 52 previously shown in
In one example, the session analyzer 52 uses the time stamp values attached to the captured UI events 34 and captured network data 38 to determine the sequence that the different events were executed or rendered during the original network session. The session analyzer 52 synchronizes the captured UI events 34 and captured network data 38 using the time stamp values then replaying or recreating the original network session.
For example, network data 26 associated with transferring web page 18 to the client 14 in
Any portion of the synchronization process can be automatically replayed by the session analyzer 52. For example, session replay can be specified for a particular window of time or for a particular portion or stage of a captured network session.
Recreating Network Sessions
It is worth noting that in some network sessions, error message 106 might have only been generated locally on the terminal rendering web page 100. Accordingly, the network data 26 shown in
The UI event monitor 16 allows the capture and recreation of these locally generated UI events that can then be used to more effectively identify network session problems. For example, the session analyzer 52 can recreate the network session then identify the error message 106 that may not have ever been persistently stored during the original network session 50. The web application administrator can also use this recreated network session to discover normally non-detectable network session problems, such as the bug that deleted the shopping cart item from fields 102D and 102E.
From the session replay shown in
The session identifiers associated with UI events and network data can also be used for analyzing other types of network session problems. For example, different types of errors can be tracked according to the time stamps associated with the captured information. Network sessions can also be analyzed according to different types of web browsers, different types of web operations, system performance, web pages last used, common information presented in the web page, last event initiated by the user, last event received from the web application, etc.
Capturing Non-Persistent Local Network Session Events
During a network session, the web application may send network data 230 that includes web page data 214, logic that operates the UI event monitor 16, and web page logic 210. The web page logic 210 is used for conducting different local operations associated with the network session. For example, the web page logic 210 can be used to check for correct entries in fields 216-224 of web page 214. In one example, the web page logic 210, among other things, is used for verifying a nine digit number is entered into the social security number field 224.
Current web applications also may not necessarily send new web pages for each new web page state. For example, the web application may supply certain base web pages, such as web page 214, during the web session. Then based on a user selection or entry 232, the web application may respond with other information 234 that is used with the same base web page 214. The ETR system 12 can be used to recreate web sessions that use any of these different types of web applications.
In this example, a user may have initiated the web session by entering an http or https address through the web browser 208. The web application associated with the address responds back with web page data that includes web page 214, web page logic 210, and the UI event monitor 16. The web page 214 is rendered on the user interface 15 via web browser 208. In this example, the web page 214 is used for providing car insurance quotes. Of course, any other type of information can be provided on web page 214. The web page 214 includes a car manufacturer field 216, a car model field 218, address fields 220 and 222, and a Social Security Number (SSN) field 224.
In this example, a user entered a car manufacturer name into field 216. This information is sent back to the web application as user selection 232. Accordingly, the web application may send back additional web session information 234. For example, if the user enters a particular car manufacturer name into field 216, the web application may then send back all of the car models associated with the selected car manufacturer in one of the responses 234. These associated car models may then be displayed in a drop down menu in car model field 218.
The user may then supply or select other UI inputs 232 such as the car model and year. Accordingly, the web application may send back other responses 234 that in this example, include the same or another web page 214 that requests the user to enter personal information, such as shown by address fields 220 and 222, and a social security number in SSN field 224. The user input into fields 220, 222, and 224, may then be sent back to the web application as UI inputs 236. If all of the user inputs 232 and 236 are in the proper form, the web application then sends back a car insurance quote in response 238 which is displayed on web page 214.
In this example, the web page logic 212 performs the nine digit SSN check locally at the terminal. If the social security number is incorrectly entered into SSN field 224, the web page logic 212 displays an error message 226 on web page 214.
This error message 226 may never be transmitted over the network 28 to the web application. Further, the error message 226 may never be persistently stored by the web terminal. For example, the error message 226 may only temporarily be displayed on web page 214 until another social security number is entered into SSN field 224. After another social security number is entered, or if the web session is terminated, there is no further evidence that the error message 226 was ever displayed.
In a second web page state 214B, the captured UI events 232A and 232B are applied to the rendered web page 214 in the same order originally entered during the web session. For example, the user may have initially entered a car manufacturer name 232A into field 216. This may have prompted the web page logic 210 to send a request back to the web application for all car model names associated with the specified manufacturer name 232A. This may have accordingly caused the web application located on the server to send back responses 234 listing all of the relevant car model names. Accordingly, the next captured UI event 232B may have selected one of the listed car model names 234.
Another web page state 214C shows the session replay immediately after the user entered the incorrect social security number 206 into SSN field 224. It should be noted that the user event 206 may have only happened locally on the network terminal. This is distinguished from other user inputs 232A and 232B that, in this example, may have been forwarded over the network connection 28 (
The session analyzer 52 in
In operation 300, the session analyzer 52 receives a replay request to identify certain specified events for a particular network session. There can be any number of network sessions that may be identified. For example, network sessions for particular users, for a particular time of day, for a particular web application or web server, etc. The session analyzer 52 in operation 302 identifies the captured network data and UI events for the relevant network sessions. The session analyzer 52 may use the session identifiers assigned to the captured network data and the captured user interface events to identify the relevant captured information.
In operation 304, the session analyzer 52 synchronizes the captured UI events with the captured network data in a similar order as previously executed during the original network session. A virtual replay is performed for the network session in operation 306 by applying the synchronized UI events to the synchronized network data. The virtual replay provides a rendering in substantially the same manner as originally rendered during the network session. The re-rendered network session can accordingly recreate messages, events, or states that may have only occurred locally on the web terminal or that were never persistently stored after originally being rendered during the original network session.
In operation 308, the session analyzer scans the re-rendered network session for specified events, messages, states, etc. Screen scanning is well known and is therefore not described in further detail. Any identified events are then captured in operation 310 for further analysis of the user experience in the original network session.
The virtual replay described above can also be used to identify and capture more complex web page operations and states. For example, the virtual replay can track and capture Document Object Model (DOM) or Asynchronous JavaScript Technology and XML (AJAX) events performed during the original network session. This JavaScript technology allows a HTML page to asynchronously make calls to the server from which it was loaded and fetch XML documents. The XML documents may then be used by the JavaScript technology to update or modify the Document Object Model (DOM) of the HTML page.
The virtual replay can reproduce these AJAX events and states that otherwise may not be detected simply by monitoring network data. For example, the AJAX code may be used to retrieve different components for an existing page from the web application 43 running on the server 42 in
The UI event monitor 16 in combination with the network session monitor 36 in
Selective Event Archival
Referring to
The session analyzer 52 can be configured to search through the session archive 40 on some configurable periodic time period and extract all of the conflict resolution events that correspond with a set of preconfigured filters. For example, the session analyzer 52 may identify web pages that complete an online purchase. Similarly, any UI events that indicate a user selected a purchase icon can also be identified and extracted for long term archival.
In one embodiment, different dispute resolution events can be assigned particular identifiers that are then used by the session analyzer 52 (
In one embodiment, the identified dispute resolution data and any associated session parameters, such as the network session ID, source and destination IP addresses, time of day, session duration, transaction summary, etc., can be extracted from the event metadata in operation 324 and summarized. The summarized information can then be converted into a non-editable file format, such as a Portable Document Format (PDF) file.
The identified dispute resolution events can also be converted in operation 324 into a non-editable file format and saved along with the session summary. Of course, other types of file formats can be used and do not have to be non-editable. The identified and converted dispute resolution events are then stored either in a long term location in the session archive 40 in
Only a small portion of captured events may have dispute implications. Therefore, these particular types of events can be stored for longer periods of time without overloading enterprise storage archives. Other non-dispute related events may be stored in the session archive for shorter periods of time.
Whenever a particular user has a dispute, the enterprise administrator can call up all archived files for the identified user. Alternatively, the enterprise administrator can call up all transactions that may have occurred during a particular time period to locate the relevant network session. The summary page can be viewed and the different identified events selected to then replay the information previously displayed to the user and replay the actions that were previously performed by the user during the archived network session.
Converting the identified dispute resolution data into a non-editable file format reduces some of the issues regarding possible tampering of the archived session. A signature can also be generated for the PDF files that contain the complete set of all captured UI events and network data related to the dispute resolution activities. The signature can then be separately stored to confirm the authenticity of the PDF files.
Capturing Syndicated Content
Web applications and network sessions may provide or use content from third party web applications. For example,
A UI event and network session monitor 354 is operated on client 350 and captures any UI events or network data associated with the network session A. For example, the network data 352 and 362 exchanged between web application 365 and client 350 is captured as well as the network data 360 exchanged between the web application 359 and client 350. In addition, all UI events that occur locally on client 350 during network session A are also captured. The UI events may be responsive or interact with network data 362 exchanged with web application A or network data 360 exchanged with web application B.
All of the network data and UI events related to the network session A conducted through web application 365 and web application 359 are then sent to a session archive 370. The session analyzer 52 (
Analyzing Network Session Times
As described above, the ETR system 12 may assign time stamps to different captured network data and UI events. These time stamps can be used to further analyze the user experience during a network session. Referring to
For example, UI events 410 are captured after the network data 402 and may include the entry of a credit card number 410A into the credit card number field 404B of web page 404A and selection 410B of the buy icon 404C in web page 404A. Similarly, the ETR system assigns one or more time stamp values 410C to the captured UI events 410.
Comparing the time stamp value 405 for the captured network data 402 with the time stamp value 410C for the captured UI events 410 can provide further insight into the user experience during a network session. For example, comparing multiple different network sessions may indicate that most completed online transactions occur within 5 minutes of the web application presenting the purchaser input information 404.
It was previously determined from the network session time analytics in
In operation 456, the session analyzer 52 can also, or alternatively, identify the time required to complete different session events. For example, instead of, or in addition to, determining the time between different network data and UI events, the session analyzer 52 may determine an amount of time required to select an item for purchase, the amount of time required to complete the entire network session, or the amount of time required to complete different activities during the same network session. This can be done by identifying the time stamp value for a first session operation and then comparing this with the time stamp value for a final session operation.
In yet another analytic, the session analyzer 52 in operation 458 may identify the time stamp values for captured network data and UI events associated with identified transaction errors. For example, the time stamp values may be identified for a UI event or network data immediately preceding or following an identified error message. Alternatively, the session analyzer 52 can use the time stamp values to determine how long it takes a user to resolve an identified error message and complete the online transaction.
The system described above can use dedicated processor systems, micro controllers, programmable logic devices, or microprocessors that perform some or all of the operations. Some of the operations described above may be implemented in software and other operations may be implemented in hardware.
For the sake of convenience, the operations are described as various interconnected functional blocks or distinct software modules. This is not necessary, however, and there may be cases where these functional blocks or modules are equivalently aggregated into a single logic device, program or operation with unclear boundaries. In any event, the functional blocks and software modules or features of the flexible interface can be implemented by themselves, or in combination with other operations in either hardware or software.
Having described and illustrated the principles of the invention in a preferred embodiment thereof, it should be apparent that the invention may be modified in arrangement and detail without departing from such principles. We claim all modifications and variation coming within the spirit and scope of the following claims.
This application is a continuation of U.S. patent application Ser. No. 11/616,616, entitled: METHOD AND APPARATUS FOR SYNCHRONIZING USER INTERFACE EVENTS WITH NETWORK DATA, filed Dec. 27, 2006 now U.S. Pat.
