-In this article, you'll learn how to download the Apache JMeter logs for Azure Load Testing Preview in the Azure portal. You can use the logging information to troubleshoot problems while the Apache JMeter script runs.
+Learn how to diagnose and troubleshoot errors while running a load test with Azure Load Testing Preview. Download the Apache JMeter worker logs or load test results for detailed logging information.
 
-The Apache JMeter log can help you identify problems in your JMX file, or run-time issues that occur while the test is running. For example, the application endpoint might be unavailable, or the JMX file might contain invalid credentials.
+When you start a load test, the Azure Load Testing test engines run your Apache JMeter script. Errors can occur at different levels. For example, during the execution of the JMeter script, while connecting to the application endpoint, or in the test engine instance.
 
-When you run a load test, the Azure Load Testing test engines execute your Apache JMeter test script. While your load test is running, Apache JMeter stores detailed logging information in the worker node logs. You can download the JMeter worker node log for your load test run from the Azure portal to help you diagnose load test errors.
+There are several load test error indicators available:
+
+- The test run **Status** information is **Failed**.
+- The test run statistics shows a non-zero **Error percentage** value.
+- The **Errors** graph in the client-side metrics shows errors.
+
+You can use different sources of information to diagnose these errors:
+
+- [Download the Apache JMeter worker logs](#download-apache-jmeter-worker-logs) to investigate issues with JMeter and the test script execution.
+- [Export the load test result](./how-to-export-test-results.md) and analyze the response code and message for each HTTP request.
+
+There might also be problems with the application endpoint itself. If you host the application on Azure, you can [configure server-side monitoring](./how-to-monitor-server-side-metrics.md) to get detailed insights about the application components.
