Application server monitors in loadrunner

If perfmon is available in your workstation. This feature in controller calls the perfmon dll and counters can be added to monitor the behavior of the whatever windows workstation that is needed. Monitor system bottlenecks during a test run and capture and display the performance data from every server or component.

We can monitor the system resources like memory, cpu uiilization. With Loadrunner, we can see the response of the system, CPU utilization while it is being used by multiple users and subjected to stress.

Monitor Types LoadRunner

You need to have proper licenses for monitoring the servers be it either web, app or db server. We can monitoring the performance of the application under test. While examing the application and working on the script, we have to check the bottleneck and examine the various graphs throughput, response time of the server on load and many more Most of the time we check at what condition is our application breaks This is what the bottleneck of the system. While a Web server mainly deals with sending HTML for display in a Web browser, an application server provides access to business logic for use by client application programs.

The application program can use this logic just as it would call a method on an object or a function in the procedural world. Such application server clients can include GUIs graphical user interface running on a PC, a Web server, or even other application servers. The information traveling back and forth between an application server and its client is not restricted to simple display markup.

Instead, the information is program logic. Since the logic takes the form of data and method calls and not static HTML, the client can employ the exposed business logic however it wants. Moreover, the application server manages its own resources.

Such gate-keeping duties include security, transaction processing, resource pooling, and messaging. Like a Web server, an application server may also employ various scalability and fault-tolerance techniques. Lets see the below example: As an example, consider an online store that provides real-time pricing and availability information.

Most likely, the site will provide a form with which you can choose a product. When you submit your query, the site performs a lookup and returns the results embedded within an HTML page. The site may implement this functionality in numerous ways.

Setting Monitor Options LoadRunner

I'll show you one scenario that doesn't use an application server and another that does. Seeing how these scenarios differ will help you to see the application server's function. Scenario 1: Web server without an application server In the first scenario, a Web server alone provides the online store's functionality. When you save a scenario, the online monitor configuration settings are saved as well.

The Monitors Tab lets you enable the Transaction monitor, configure the behavior of the transaction data, and set the data sampling rate, error handling, debugging, and frequency settings for the online monitors. Transaction Data: Server Resource Monitors: Configures the behavior of the Server Resource monitors.

The data sampling rate you set is applied to all server monitors that you subsequently activate. It is not applied to server monitors that have already been activated.

Types of Monitoring

To apply the new data sampling rate to activated server monitors, save your scenario and reopen it. Each monitor has a different minimum sampling rate. For example, the minimum sampling rate for the Oracle Monitor is 10 seconds.

If the sampling rate in the Options Monitors tab is set at less than 10 seconds, the Oracle Monitor will continue to monitor data at 10 second intervals. Error Handling: Controls the way in which LoadRunner issues error messages. Select one of the following options. Display debug messages: Sends debug-related messages to the output log. You can also specify a debug level from The debug level is only relevant to the Network monitor. Creating A Goal-oriented Scenario.
