I have an Asp.net core web api project and i've added the simplest configuration of application insights in Startup.cs file.
services.AddApplicationInsightsTelemetry();
Everything is fine and the data is sent to Azure correctly, but now I need to stop tracking data from a specific controller because it makes a request to an external api and when it fails i'm able to control the flow but i dont want to see those error un application insights portal.
You can use telemetry processor to filter out the data from the specified controller, sample code like below:
public class CustomControllerFilter : ITelemetryProcessor
{
private ITelemetryProcessor Next { get; set; }
public CustomControllerFilter(ITelemetryProcessor next)
{
this.Next = next;
}
public void Process(ITelemetry item)
{
RequestTelemetry telemetry = item as RequestTelemetry;
if (telemetry != null)
{
//the test controller
if (telemetry.Url.AbsoluteUri.Contains("/test/"))
{
return;
}
}
this.Next.Process(item);
}
}
Then register it in Startup.cs -> ConfigureServices method:
public void ConfigureServices(IServiceCollection services)
{
//other code
services.AddApplicationInsightsTelemetry();
//register it here
services.AddApplicationInsightsTelemetryProcessor<CustomControllerFilter>();
}
You can create a method to disable it and call on the controller. This method would include:
TelemetryConfiguration.Active.DisableTelemetry = true;
Another option would be modifying appsettings.json to control the logging done by ApplicationInsights. Something like the following in appsettings.json ensure Applicationinsights only sends traces for logs with severity >= Warning.
{
"Logging": {
"IncludeScopes": false,
"Debug": {
"LogLevel": {
"Default": "Trace"
}
},
"Console": {
"LogLevel": {
"Default": "Warning"
}
},
"ApplicationInsights": {
"LogLevel": {
"Default": "Warning"
}
}
}
}
