Complete the C# code below to define a custom telemetry processor that filters out successful dependency telemetry and register it within the ASP.NET Core dependency injection container.
Cevap:public class DependencyFilter : 【ITelemetryProcessor】
{
private ITelemetryProcessor Next { get; set; }
public DependencyFilter(ITelemetryProcessor next)
{
this.Next = next;
}
public void Process(ITelemetry item)
{
if (item is DependencyTelemetry dependency && dependency.Success == true)
{
return; // Filter out
}
this.Next.Process(item);
}
}
// In Program.cs:
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddApplicationInsightsTelemetry();
builder.Services.【AddApplicationInsightsTelemetryProcessor】<DependencyFilter>();
{
private ITelemetryProcessor Next { get; set; }
public DependencyFilter(ITelemetryProcessor next)
{
this.Next = next;
}
public void Process(ITelemetry item)
{
if (item is DependencyTelemetry dependency && dependency.Success == true)
{
return; // Filter out
}
this.Next.Process(item);
}
}
// In Program.cs:
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddApplicationInsightsTelemetry();
builder.Services.【AddApplicationInsightsTelemetryProcessor】<DependencyFilter>();
Cevap
Implement the ITelemetryProcessor interface for the filter class, and register the class in the ServiceCollection using the AddApplicationInsightsTelemetryProcessor extension method.
To create a custom telemetry filter, the class must implement ITelemetryProcessor and its Process method. To register it in an ASP.NET Core application, use the AddApplicationInsightsTelemetryProcessor service extension method. This registers the processor so it is executed for every telemetry item passing through the telemetry pipeline.
