Setting CustomDimensions with the Microsoft Extension Logging framework

Question

I have set up application insights for asp.net core project.

appsettings.json:

  "ApplicationInsights": {
    "InstrumentationKey": "90f786b7-36a5-xxxx-b1fc-xxxxxxxxx"
  },

Startup.cs:

services.AddApplicationInsightsTelemetry();

And in my controller I can now log:

Logger.LogDebug("LogDebug");

I cant find any information on how to set CustomDemensions. I can see on the overloads there is an object array but not sure if that if for customdimensions. Any pointers?

Updated:

            var dict = new Dictionary<string, object> { { "user_name","ivan"},{ "mycity","new york"} };

            using (_logger.BeginScope(dict))
            {
                _logger.LogInformation("this is a test message for testing purpose 456");
            }

Original answer:

For example, if you want to add the 2 properties city / user in customDimentions, please use the code below in the controller:

string city = "london";
string user = "jack";
_logger.LogInformation("{user} sends a  message from {city}", user, city);

Then in azure portal -> application insights logs:

WOW thanks. But that is really strange:D What if you don't want the parameters in your text? – Thomas Segato May 18 '20 at 06:19
I tried following but then it does not add the dimensions: Logger.LogDebug("LogDebug", lol1, lol2); – Thomas Segato May 18 '20 at 06:51
@ThomasSegato, let me try if it can work if without parameters in the text:). – Ivan Glasenberg May 18 '20 at 07:38
Thanks Ivan appreciated. – Thomas Segato May 18 '20 at 08:15
@ThomasSegato, another way is to use BeginScope method, see the updated section. – Ivan Glasenberg May 18 '20 at 08:18
Worked - highly appreciated. Thanks! – Thomas Segato May 18 '20 at 08:36
