Simulated Web Transactions Test

This test emulates a user logging into a web application being monitored by the Web App Simulator tool. In the process, the test reports the availability and responsiveness of the web application. The activities that were successful and that failed are measured and reported along with the total simulation time. Additionally, the test also captures failures (if any) at each step of the simulation. Using the insights provided by this test, administrators can proactively detect logon slowness/failures and precisely pinpoint the root-cause of the anomaly. This way, web administrators are enabled to isolate the probable pain-points of their web application, even before users begin to actively use the web application.

Target of the test : A web site or a web application

Agent deploying the test : An external agent

Outputs of the test : One set of results for every transaction in each recorded script

Configurable parameters for the test

Parameters

Description

Test period

How often should the test be executed. The default is 5 minutes. The default is 15 minutes.

Host

The host for which the test is to be configured

Port

Refers to the port used by the target web application

SCRIPT NAME

By default, the scripts that are available for simulation will be listed in this list box. You can select one/more scripts from this list for monitoring. eG Enterprise is also capable of monitoring the scripts that are recorded and exported by more than one user using a single component. For this purpose, a separate icon is provided against this parameter. Clicking the icon will lead you to Figure 1.

Figure 1 : Choosing the Script file

In Figure 1, select the user who has recorded one/more scripts to be monitored from the User Name list.

The scripts corresponding to that user will be populated in the Script File list box. Select the script and click the Submit button. You are allowed to choose more than one User Name:Script File combination.

Console Username

The simulator needs to run in the account of a user who has local administrator rights on the simulation end point - i.e., the system on which the external agent is installed. Specify the name of this user here. This user should also be logged in at all times for the simulator to run continuously.

Console Domain

Specify the domain to which the Console Username belongs to. By default, none is specified against this parameter.

Success Screenshot Required

By default, this flag is set to No. If this flag is set to Yes, then , if all the transactions for the script were completed successfully, an additional screenshot will be offered for the Transaction availability measure of the Total descriptor.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test

Figure 2 : The measures reported by the Simulated Web Transactions test

Measurement Description Measurement Unit Interpretation

Transaction availability

Indicates whether/not this transaction is completed successfully.

Percent

The value 100 for this measure indicates that the transaction was completed successfully, and the value 0 indicates that transaction failed.

If this measure reports the value 0, then no other measures will be reported for that transaction.

You can also use the detailed diagnosis of this measure to view the output of the simulation script, scrutinize it, and isolate the failure and problem points of the web application at first glance.

Transaction processing time

Indicates the time taken by this transaction for execution.

Secs

Compare the value of this measure across the transactions to figure out the transaction that is taking too much time for execution.

Total activities

Indicates the total number of activities performed by this transaction.

Number

 

Successful activities

Indicates the number of activities that were successfully performed by this transaction.

Number

Compare the value of this measure across transactions to figure out the transaction for which least number of activities were successful.

Failed activities

Indicates the number of activities that failed for this transaction.

Number

Compare the value of this measure across transactions to figure out the transaction for which the maximum number of activities failed.

Activities successfully completed

Indicates the percentage of activities successfully completed for this transaction.

Percent

The value 100 for this measure indicates that the activities were successfully completed, and the value 0 indicates that the activities failed to complete.

By comparing the value of this measure across transactions, you can quickly identify the transactions for which the activities failed to complete successfully.

Total simulation time

Indicates the total time taken to simulate this transaction.

Secs

This measure is applicable only for the Total descriptor.

An abnormally high value for this measure could indicate a logon slowness.

The detailed diagnosis of the Transaction availability measure will appear only when a value of 0 is reported. Clicking the icon will lead you to the screenshot which visually indicates the exact transaction at which the script failed during simulation. Clicking the icon will directly open the screenshot at which the transaction failed.

Use the Details section of the detailed diagnosis to view the transaction flow, output of the simulation script, scrutinize it, and isolate the failure and problem points of the web application at first look. A summary of the simulation is also provided as part of the detailed diagnostics.
