TelemetryClient is a tool commonly associated with Application Insights, a feature of Azure Monitor that provides extensible application performance management (APM) and monitoring for live web applications. It enables developers to collect and analyze telemetry data from their applications to diagnose issues and understand user behavior. While TelemetryClient is typically used in the context of web applications, it can also be utilized in a Windows environment to monitor desktop applications or services.
In this article, we will explore how to set up and use TelemetryClient in a Windows environment. We will cover the installation process, basic configurations, and provide examples of how to send telemetry data from a Windows application. This is particularly useful for developers who want to gain insights into the performance and usage of their desktop applications.
Examples:
Setting Up TelemetryClient in a Windows Application
First, you need to install the Application Insights SDK for .NET. You can do this using the NuGet Package Manager in Visual Studio:
Install-Package Microsoft.ApplicationInsights
Alternatively, you can use the Package Manager Console:
PM> Install-Package Microsoft.ApplicationInsights
Configuring TelemetryClient
After installing the SDK, you need to configure the TelemetryClient with your Application Insights instrumentation key. This key is unique to your Application Insights resource in Azure.
using Microsoft.ApplicationInsights;
using Microsoft.ApplicationInsights.Extensibility;
public class TelemetryConfiguration
{
private static TelemetryClient telemetryClient;
static TelemetryConfiguration()
{
var config = TelemetryConfiguration.CreateDefault();
config.InstrumentationKey = "YOUR_INSTRUMENTATION_KEY";
telemetryClient = new TelemetryClient(config);
}
public static TelemetryClient GetTelemetryClient()
{
return telemetryClient;
}
}
Sending Telemetry Data
With the TelemetryClient configured, you can start sending telemetry data such as events, metrics, and exceptions. Here are some examples:
Sending a Custom Event
var telemetryClient = TelemetryConfiguration.GetTelemetryClient();
telemetryClient.TrackEvent("CustomEventName");
Sending a Metric
telemetryClient.TrackMetric("CustomMetricName", 42);
Sending an Exception
try
{
// Code that may throw an exception
}
catch (Exception ex)
{
telemetryClient.TrackException(ex);
}
Running the Application
Once you have added the telemetry tracking code to your application, you can run it as usual. The telemetry data will be sent to Application Insights, where you can analyze it using the Azure portal.
