The present disclosure relates generally to data analysis and more particularly, but not by way of limitation, to systems and methods for end-to-end response time analysis.
Modern web applications process millions of transactions per day and can include multiple redundant layers. When problems occur, it can be difficult to trace the problem to a particular layer. Typical reports and alerts regarding transactions are complex and do not adequately indicate a root cause of poor-performing transactions.
Moreover, as the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
In one embodiment, a method is performed by a computer system comprising physical computer hardware. The method includes selecting a group of transactions having a common end-to-end transaction path comprising a plurality of transaction-path nodes. Each transaction of the group is associated with either an acceptable category or an unacceptable category based, at least in part, on an end-to-end response time for the transaction. The method further includes separately determining, for each transaction-path node, an execution-time pair. The execution-time pair includes first aggregate information indicative of execution time by the transaction-path node for transactions associated with the acceptable category. The execution-time pair also includes second aggregate information indicative of execution time by the transaction-path node for transactions associated with the unacceptable category. Additionally, the method includes generating a visualization of the end-to-end transaction path. The visualization depicts each determined execution-time pair in relation to a corresponding transaction-path node.
In one embodiment, an information handling system includes a processing unit, wherein the processing unit is operable to implement a method.

Additionally, the method includes generating a visualization of the end-to-end transaction path. The visualization depicts each determined execution-time pair in relation to a corresponding transaction-path node.
In one embodiment, a computer-program product includes a non-transitory computer-usable medium having computer-readable program code embodied therein. The computer-readable program code is adapted to be executed to implement a method. The method includes selecting a group of transactions having a common end-to-end transaction path comprising a plurality of transaction-path nodes. Each transaction of the group is associated with either an acceptable category or an unacceptable category based, at least in part, on an end-to-end response time for the transaction. The method further includes separately determining, for each transaction-path node, an execution-time pair. The execution-time pair includes first aggregate information indicative of execution time by the transaction-path node for transactions associated with the acceptable category. The execution-time pair also includes second aggregate information indicative of execution time by the transaction-path node for transactions associated with the unacceptable category. Additionally, the method includes generating a visualization of the end-to-end transaction path. The visualization depicts each determined execution-time pair in relation to a corresponding transaction-path node.
A more complete understanding of the method and apparatus of the present invention may be obtained by reference to the following Detailed Description when taken in conjunction with the accompanying Drawings wherein:
In various embodiments, a performance-monitoring system can track and trace end-user (EU) transactions. The performance-monitoring system can produce and store, for example, an end-to-end (E2E) response time for each EU transaction. An EU transaction, as used herein, is initiated by an EU request such as, for example, a web request, includes subsequent processing of the request by a backend-computing system, and is concluded by a web response from the backend-computing system. EU transactions can cross multiple nodes such as, for example, a web browser, a web server, an application server, a database, one or more external services, etc. An E2E response time can include, for example, a time elapsed from initiation through conclusion of an EU transaction.
One way to troubleshoot slow transaction performance is to aggregate E2E response times for a group of EU transactions and examine execution times at each node in an E2E transaction path. An E2E transaction path typically includes a set of nodes through which a given transaction passes. The E2E transaction path can be, for example, application-specific (e.g., web-application-specific). An E2E response time is typically made up of an execution time at each node in the E2E transaction path. For example, consider an exemplary E2E transaction path that includes a web browser, a network, a web server, an application server, and a database. Each E2E response time can be composed of execution times at each of the web browser, the network, the web server, the application server, and the database. For purposes of troubleshooting, execution times for a group of EU transactions can be aggregated, for example, by determining a mean, median, or mode, performing a statistical analysis, etc. From this information, it can be determined where transactions generally spend the most time. Manual root-cause analysis can subsequently occur.
A downside of the above-mentioned approach is that significant performance aberrations may become diluted in the aggregations. For example, it may be that each poor-performing transaction spends an excessively long period of time at the application server. However, until the poor-performing transactions become abundant in number, the aggregate execution times at the application server may not be indicative of a major problem and thus may not be useful in performing a root-cause analysis. In addition, it may not be immediately apparent what constitutes an excessively long execution time or to what degree a given execution time is excessive.
Various embodiments described herein facilitate a comparative performance analysis between acceptable EU transactions and unacceptable EU transactions. For example, in certain embodiments, each EU transaction can be associated with either an acceptable category or an unacceptable category based, at least in part, on whether an E2E response time exceeds a configurable threshold. The configurable threshold can be an absolute value (e.g., defined in seconds), a relative value (e.g., defined relative to a mean or median value for a transaction type), and/or the like. The configurable threshold can also be varied by type of transaction (e.g., log-in, checkout, etc.).
For purposes of aggregate analysis, an execution-time pair can be separately determined for each node along an E2E transaction path. The execution-time pair can include, for example, a first aggregate execution time for a group of EU transactions associated with the acceptable category and a second aggregate execution time for a group of EU transactions associated with the unacceptable category. Each aggregate execution time can represent a mean, median, mode, etc. Other methods of aggregation can also be used. Advantageously, in certain embodiments, this method enables simplified analysis of each node's performance in unacceptable transactions as compared with that same node's performance in acceptable transactions. In certain embodiments, when each node of the E2E transaction path is presented in this manner, it can more easily be determined which node or nodes are causes of the unacceptable transactions.
Backend performance data, as used herein, refers to data collected during runtime of a software application such as, for example, a web application, through instrumentation of the software application. EU-experience data, as used herein, refers to data collected through observation of one or more transactions from an EU perspective. For example, in various embodiments, the EU perspective may be a node between a web server and an EU information handling system, a node between a web server and an application server, or the EU information handling system.
For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, calculate, determine, classify, process, transmit, receive, retrieve, originate, switch, store, display, communicate, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer (e.g., desktop or laptop), tablet computer, mobile device (e.g., personal digital assistant (PDA) or smart phone), server (e.g., blade server or rack server), a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, touchscreen and/or a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components.
For illustrative purposes, the backend-computing system 110 is shown to utilize a three-tier architecture that includes a presentation tier 116, a logic tier 114, and a data tier 112. The presentation tier 116 includes at least one information server 138 such as, for example, a web server, that serves content to be rendered by the client application 104. The logic tier 114 includes at least one application server 136 that operates a platform based on, for example, Java EE, ASP.NET, PHP, ColdFusion, Perl, and/or the like. The data tier 112 includes at least one database 134 that further includes, for example, data sets and a database management system that manages and provides access to the data sets.
It should be appreciated that, in various embodiments, the backend-computing system 110 may include any number of tiers. In addition, in various embodiments, the backend-computing system 110 may implement various alternative architectures such as, for example, a model-view-controller architecture. It should also be appreciated that the at least one application server 136 and the at least one information server 138 are shown separately in
The backend-computing system 110 executes one or more distributed software applications such as, for example, a web application, from which backend-performance data is collected. In a typical embodiment, the one or more distributed software applications have been instrumented to provide the backend-performance data. Each of the one or more distributed software applications may be, for example, a collection of software components or services that make up an application stack. In various embodiments, the backend-computing system 110 may use an agent resident thereon to collect the backend-performance data.
The backend-performance data can include, for example, metrics related to infrastructure components (virtual or physical) such as, for example, the at least one database 134, the at least one application server 136, and the at least information server 138. The backend-performance data can also include aggregated metrics related to infrastructure tiers such as, for example, the presentation tier 116, the logic tier 114, and the data tier 112. In addition, the backend-performance data can include metrics related to the application stack for each of the one or more distributed software applications. In a typical embodiment, the backend-performance data can trace EU transactions through a topology of nodes that can include, for example, infrastructure components, infrastructure tiers, and/or application-stack components as described above. Metrics can include, for example, execution time at each tier or by each component or node. Examples of how backend-performance data can collected and managed is described in detail in U.S. Pat. Nos. 7,979,245 and 8,175,863, each of which is hereby incorporated by reference.
The data collector 108 is a software component that collects the EU-experience data for the at least one EU information handling system 102. In a typical embodiment, the data collector 108 is situated in the system 100 such that the data collector 108 is capable of seeing all network traffic (i.e., all packets exchanged) between the at least one EU information handling system 102 and the backend-computing system 110. In this fashion, the data collector 108 functions as a packet analyzer and is operable to extract the EU-experience data and transmit the EU-experience data to the EU archive system 126. The EU archive system 126 includes at least one server computer 128 and at least one database 130. The EU archive system 126 receives the EU-experience data from the data collector 108 and stores the EU-experience data in the at least one database 130. An example of how EU-experience data can be collected is described in U.S. Pat. No. 7,941,385. U.S. Pat. No. 7,941,385 is hereby incorporated by reference.
As illustrated, the data collector 108 can reside at various nodes in the system 100. For example, the data collector 108 can reside on the backend-computing system 110 between the presentation tier 116 and the logic tier 114. The data collector 108 can also be resident on the backend-computing system 110 between the presentation tier 116 and the network 106. In addition, in various embodiments, the data collector 108 is representative of client-side scripting that is executed on the at least one EU information handling system 102. In this fashion, the data collector 108 can also be resident on the at least one EU information handling system 102. It should be appreciated that other locations for the data collector 108 such as, for example, within the presentation tier 116, are also contemplated.
The monitoring system 118 includes at least one server computer 120 and at least one database 122. The at least one server computer 120 is operable to execute a correlator 124. The correlator 124 is typically a software component that correlates the EU-experience data maintained by the EU archive system 126 with the backend-performance data maintained by the monitoring system 118 to yield E2E response times for EU transactions. Exemplary operation of the system 100 will be described with respect to
The administrative system 140 includes a reporting module 142. The administrative system 140 can include any number of server computers and/or databases. The reporting module 142 can include hardware and/or software for generating and/or presenting alerts, reports, and/or the like based on data stored or generated by the monitoring system 118 and the EU archive system 126. The reports and/or alerts can be served to an administrative user using, for example, an information handling system similar to the EU information handling system 102. For example, in certain embodiments, the reporting module 142 can facilitate a comparative performance analysis between acceptable EU transactions and unacceptable EU transactions. An example of functionality of the reporting module 142 will be described with respect to
One of ordinary skill in the art will appreciate that each instance of a computer or computer system as described above may be representative of any number of physical or virtual server computers. Likewise, each instance of a database may be representative of a plurality of databases. In addition, it should be appreciated that, in various embodiments, each instance of a network such as, for example, the network 106 or the network 132, can be viewed as an abstraction of multiple distinct networks. For example, the network 106 and the network 132 can each include one or multiple communications networks such as, for example, public or private intranets, a public switch telephone network (PSTN), a cellular network, the Internet, or the like. In addition, in various embodiments, the network 106 and the network 132 may overlap or refer to a same network.
A monitoring agent on the at least one application server 136 injects the identifier in a response to the request (i.e., a UUID-injected response), which response is directed to the at least one EU information handling system 102 along a transmission path that includes that at least one information server 138 and the at least one EU information handling system 102. In this fashion, no modification of application code is required to inject the identifier. Rather, the monitoring agent, which is already being utilized for existing instrumentation of the distributed software application, injects the identifier into the response. The response may be a web response such as, for example, an HTTP response. In various embodiments, the identifier can be injected, for example, into a response header for the response. In some embodiments, the identifier may be inserted into a cookie that is sent as part of the response header. Content of the UUID-injected response is rendered on the at least one EU information handling system 102 via the client application 104.
As noted above, the data collector 108 is situated on the system 100 so that the data collector 108 can observe all network traffic exchanged between the backend-computing system 110 and the EU information handling system 102. Therefore, the data collector 108 is effectively a transparent node along the transmission path. The data collector 108 passively observes the UUID-injected response and uses the identifier to identify EU-experience data that is collected.
The correlator 124 is operable to extract EU-experience data not previously obtained by the correlator (i.e., new EU-experience data) from the EU archive system 126. In various embodiments, the correlator 124 may operate on a periodic basis, on-demand, or in real-time. The correlator 124 is operable to correlate the EU-experience data and the backend-performance data that relates to a same transaction (i.e., a same request and response) by cross-referencing identifiers. In this manner, data resulting from instrumentation (the backend-performance data) and the EU-experience data, which is typically collected without instrumentation, can be correlated. The correlated data can be stored in the at least one database 122. The correlated data can also be used to generate E2E response times for end-use transactions. In addition, on a periodic basis (e.g., every five minutes) or on demand, the correlator 124 may aggregate the correlated data into one or more high-level transaction categories such as, for example, log-in, search, or checkout. Therefore, problems with particular transaction categories can be readily identified and appropriate alerts generated.
At block 302, the system 100 processes an EU transaction. For example, the block 302 can include tracing the EU transaction as described with respect to
At block 306, the monitoring system 118, the reporting module 142, or another component, associates the EU transaction with either an acceptable category or an unacceptable category. For example, in certain embodiments, the EU transaction can be associated with the unacceptable category if the E2E response time exceeds a configurable threshold value. Otherwise, the EU transaction can be associated with the acceptable category. The configurable threshold can be an absolute value (e.g., defined in seconds), a relative value (e.g., defined relative to a mean or median value for a transaction type), and/or the like. The configurable threshold can also be varied by type of transaction (e.g., log-in, checkout, etc.). The association can also be stored, for example, in the at least one database 122, a database on the administrative system 140, in memory of the monitoring system 118 and/or the administrative system 140, etc.
At block 402, the reporting module 142 selects a group of EU transactions that have a common E2E transaction path. For example, the group of transactions can relate to a same application or web application. The E2E transaction path includes a plurality of transaction-path nodes such as, for example, a web browser, a network, a web server, an application server, a database, an external service, and/or the like. Each transaction of the group may be of a same type or a different type. For example, in some embodiments, the selected group may be all checkout transactions over a certain period of time. By way of further example, the selected group can include a heterogeneous set of transaction types such as, for example, log-in, search, and checkout. In certain embodiments, the group of EU transactions can be transactions for which a process similar to the process 300 of
At block 404, the reporting module 142 separately determines an execution-time pair for each transaction-path node of the E2E transaction path. In general, the execution-time pair includes two aggregate representations. A first aggregate representation can be indicative of execution time by the transaction-path node of those transactions of the group that are deemed unacceptable transactions. A second aggregate representation can be indicative of execution time by the transaction-path node of those transactions of the group that are deemed acceptable transactions. An example of functionality that can be performed at the block 404 will be described in greater detail with respect to
At block 406, the reporting module 142 generates a report of the E2E transaction path. The report can be considered a breakdown, across the plurality of transaction-path nodes, of an aggregate E2E response time for the group. In general, the report indicates, or summarizes, each determined execution-time pair in relation to a corresponding transaction-path node. In certain embodiments, the report can be a visualization of the E2E transaction path. In these embodiments, the visualization may depict each determined execution-time pair in relation to the corresponding transaction-path node. In certain other embodiments, the report can be a collection of data representative of each determined execution-time pair and its corresponding transaction-path node.
At block 408, the reporting module 142 publishes the report. For example, the report can be transmitted to a system, entity, or user. In embodiments in which the report is a visualization, the block 408 can include causing the visualization to be displayed, for example, to an administrative of user of an EU information handling system such as the EU information handling system 102 of
At block 502, the reporting module 142 ascertains a category of each EU transaction of a group of EU transactions. The group can be, for example, a group that is selected as described with respect to the block 402 of
At block 504, the reporting module 142 accesses a response-time breakdown for each EU transaction of the group. Each response-time breakdown typically includes an execution time for each transaction-path node of the transaction path. At block 506, for each transaction-path node, the reporting module 142 aggregates corresponding execution times for those EU transactions of the group that are associated with the acceptable category. The aggregation can include computing a mean, median, or mode, performing a statistical analysis, or aggregating in another suitable fashion. At block 508, for each transaction-path node, the reporting module 142 aggregates corresponding execution times for those EU transactions of the group that are associated with the unacceptable category. The aggregation at the block 506 can be performed in similar fashion to the aggregation at the block 504.
More particularly, the visualization 600 illustrates unacceptable-category aggregate representations 656(1)-656(6) (collectively, unacceptable-category aggregation representations 656) and acceptable-category aggregate representations 658(1)-658(6) (collectively, acceptable-category aggregation representations 658) as described with respect to the block 404 of
In a typical embodiment, as depicted in
In various embodiments, the visualization 600 can facilitate improved root-cause analysis. In the illustrated embodiment, the one or more databases 654 is indicated to have a significant difference in response time between the unacceptable-category aggregation representation 656(6) and the acceptable-category aggregate representation 658(6). In contrast, the browser 144, the network 646, the one or more web servers 648, the one or more application servers 650, and the one or more external services 652 exhibit far less variation in performance between unacceptable transactions and acceptable transactions. For purposes of this example, the one or more databases 654 may be considered a potential root cause of the unacceptable transactions.
It should be appreciated that end-user transactions are described herein only for illustrative purposes. In certain embodiments, various principles described above relative to
In the case of a database query, certain sources of delay in database-query execution can be considered nodes of a transaction path. Execution time of a database query, or of a group of database queries could be affected by CPU time, input/output operations, lock delay, latch delay, and/or the like. In an example, a given transaction path could include a node for each of CPU time, input/output operations, lock delay, latch delay, and/or the like. According to this example, overall execution time can correspond to an end-to-end response time as described above. In certain embodiments, a report as described with respect to
Although various embodiments of the method and apparatus of the present invention have been illustrated in the accompanying Drawings and described in the foregoing Detailed Description, it will be understood that the invention is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the spirit of the invention as set forth herein.
