How do I use postsharp logging to write to applicationInsights? and How do I test that the logs are being written to application Insights?

Question

I was trying to use application Insights as my logging backend from postsharp references. I have setup the application insights and was able to see live metrics. But I am not quite sure if postsharp logging alone is able to write to application insights.

My code in Program.cs

using PostSharp.Patterns.Diagnostics;

using PostSharp.Patterns.Diagnostics.Backends.ApplicationInsights;

LoggingServices.DefaultBackend = new ApplicationInsightsLoggingBackend("InstrumentationKey");

GlobalAspects.cs file:

using PostSharp.Patterns.Diagnostics;

using PostSharp.Extensibility;

// This file contains registration of aspects that are applied to several classes of this project.

[assembly: Log(AttributeTargetTypeAttributes=MulticastAttributes.Public, AttributeTargetMemberAttributes=MulticastAttributes.Public)]

Do I need to setup anyhting in my program.cs in order to completely make use of postsharp logging to write to applicationinsights.

You need to set the default verbosity of the Application Insights logging backend to Trace to get the method call log records.

LoggingServices.DefaultBackend.DefaultVerbosity.SetMinimalLevel(LogLevel.Trace);

Thankyou. Can I filter out only certain logs? I don't want to log everything like validation messages or anything like that. Like What if I wanted to log only exceptions and errors? @AntoninProchazka – user15368519 Mar 11 '21 at 14:06
Is there any kind of reference on github or elsewhere for a complete only Postsharp Logging (without serilog) using only ApplicationInsights as backendsink that logs exceptions and information messages.#Postsharp – user15368519 Mar 11 '21 at 17:22
There are several options: 1) Set the log level to Info. (https://doc.postsharp.net/t_postsharp_patterns_diagnostics_loglevel) 2) Make the LogAttribute multicast more specific. (https://doc.postsharp.net/multicast-conceptual) 3) Use different logging profiles. (https://doc.postsharp.net/logging-customizing#buildtime) – Antonín Procházka Mar 12 '21 at 09:15
There's no such example now, but for better understanding, the ApplicationInsightsLoggingBackend passes all log records to Application Insights as TraceTelemetry.
