It is important to check error logs in Azure portal as it provides details on what happened, when it happened, how important it was, and perhaps even what the reason was. The simplest way to identify the cause of an application outage or performance problem is to check the error log and error messages which can be performed by a few methods.

When an error occurs with a code of 400 or higher, the server often displays these HTML pages to the user. 50 mistakes are retained at most and the oldest 26 are automatically eliminated after this point. When your website answers with an error notice, a detailed version of the html files is generated. This log type, which is kept on the website’s file system, is useful for enabling debugging for some problem answers. These logs have a .htm extension and indicate failure in your web app. To turn on the following setting in the Azure interface, enable and check error logs in Azure portal:

Step 1: Go to your app and choose App Service logs from the menu. 

Step 2: Choose On, followed by Save, under Detailed Error Logging.

When one of the modules involved in processing a request is taking a long time or an error occurs at some point, request traces are highly helpful. FREB, or Failed Request Tracing will provide you with detailed information from IIS via its many stacks for each unsuccessful request. These log files are also kept on the website’s file system. For most uses, it is too detailed. But, this is the log to look at if you need to dig in and want to examine every stage of a failed HTTP request.

By default, the Failed Request Tracing feature logs all unsuccessful requests with HTTP status codes between 400 and 600. The App Service file system has both detailed error logging and failed request tracing log files. You must turn on the following setting in the Azure interface to enable and check error logs in Azure portal. To do so:

Step 1: Go to your app and choose App Service logs from the menu. 

Step 2: Choose On, followed by Save, under Failed Request Tracing.
