如何在 Azure Application Insights 中使用 BeginScope（在 https://portal.azure.com 中）？

Question

My C# code is log.BeginScope("Testing Scope1"); and log.BeginScope("Testing Scope2"); . How can I use in Azure Application Insights (in https://portal.azure.com )?

Answer 1

If your code like below:

        using (_logger.BeginScope("Testing Scope1"))
        {
            _logger.LogInformation("this is an info from index page 111111");
        }

Then, after the code is executed, nav to azure portal -> your application insights -> Logs -> in the traces table, write the following query(also note that select a proper "time range"):

traces
| where customDimensions.Scope contains "Testing Scope1"
| project message, customDimensions

The screenshot is as below:

By the way, it may take a few minutes for the logs being generated. And please also set the proper log level in your application(like set the proper log level in your azure function ).
