These sections demonstrate how to utilize the Flows and Flow Analyzer tabs of the Mule Management Console to monitor and track applications on a specific server. These tabs work together to show you what's going on with the application's processing. You have to get this interactive mulesoft training course from well-experienced experts who will help you master concepts such as mule4 basics, AnyPoint studio integration techniques, testing, debugging, deploying, and managing mulesoft applications, and learning how to identify IT problems in the industry, among others. Furthermore, you might be able to use this data to debug an application.

Keeping Track of Flows

The Flows tab provides panels for tracking the flows of deployed apps on a server. The Flows tab, as well as the Flow Analyzer page and associated panels, are especially useful for diagnosing performance and memory utilization concerns.

The Flows screens show you where processing takes place and how long it takes. You can observe which flows are dealing with requests and how long it takes them to respond. The Flows page shows you where problems are emerging, and the Flow Analyzer tab helps you figure out what's going on with specific message requests that are creating these issues. You can debug flow performance and validate payload content and message attributes by tracking and auditing a flow.

This page explains how to use the Flows tab and the screens it contains. For more information about the Flow Analyzer tab, see Analyzing Message Flows.

The Flows page provides details on the flows for apps running on a specific server or servers. For application flows, you can see the summary, high-level information regarding event processing. You can also go down to get more specific data.

Message Flow Analysis

The Flow Analyzer panels allow you to trace message flows for an application, effectively allowing you to observe how an application processes messages from beginning to end. After confirming that your application processes are executing (via the Flows tab) and identifying any potential problems, switch to the Flow Analyzer tab. The Flow Analyzer tab allows you to see the source of many issues and provides advice on how to resolve them.

The Flow Analyzer displays will be particularly useful for diagnosing problems such as memory and performance limitations for both system administrators and developers. The Flow Analyzer tab is used to check the content of message payloads and message characteristics for flows. You may observe the path a message goes through processing, as well as the message content at each step, and debug the flow's performance.

Developers will benefit from delving into payload content at each stage of the message processing. They can check not only if the payload is what it should be, but also the accompanying message attributes at each stage of the process. Developers also have the option of setting encryption off or utilizing additional special transformer tools to decode messages when debugging an application if they need to access the entire payload for particular types of messages.

Message Processing Debugging

The Flow Analyzer screens aid in program troubleshooting. You may follow the application's message flow, which is the path taken by messages as they pass through the various message processors. You can also analyze the payload content of a message in detail, both before and after it is received by a parser.

Some debugging could only be done in a test environment, not in a production environment, due to security concerns such as encryption for sensitive message content.

This subject walks application developers through the general processes for using the Mule Management Console to troubleshoot an application. It includes the following topics:

• Checking the application's flow
• Checking message processors and payloads

Debugging an Example Loan Broker Application

This topic walks you through using the Flow Analyzer to detect and repair a fault in an easy loan broker application. As an application developer, you have a suspicion that the program isn't returning the bank with the best rate offer. To find this, concentrate on the loan-broker-sync flow, because you know it collects quotations from many banks and utilizes Java code to decide which bank has the best rate quote. The program logic in basic loan broker is of particular relevance to you:

• The loan-broker-sync flow takes care of the majority of the work, accepting customer loan rate requests from a browser, changing them, and sending them to the necessary message processors.
• The loan-broker-sync flow sends the request to the proper institutions and collects rate quotations once the customer's credit is authorized.
• The loan broker-sync finds the lowest quote from the list and provides the bank and quotation to the browser, using the LowestQuoteProcessor to perform the rate comparison.

Conclusion:

You learned how to monitor and track apps on a server using the Mule Management Console Flows and Flow Analyzer tabs in this article. Further, you have explored more details on flow tracking, analyzing message flow, debugging message processing, and an example of debugging loan broker applications.
