Trying to add heartbeat for my console application

Question

A discussion on github mentions that heartbeat is automatically sent when Microsoft.ApplicationInsights.Extensibility.Implementation.Tracing.DiagnosticsTelemetryModule& is added to the applicationinsights.config file. I want to create an alert in case the app hangs or crashes. Where can I track the heart beat on the AI instance? Also, currently its not sending anything . I am using .net framework 4.7.2. Am I configuring it wrong? I am not able to track the heartbeat on application insights instance. Where can I track it? Can someone provide a snippet for config file?

Answer 1

Currently, there is an issue involving this telemetry module AppServicesHeartbeatTelemetryModule .

Can someone provide a snippet for config file?

There is given a temporary workaround for WorkerServices.

• Add application insights to worker service using services.AddApplicationInsightsTelemetryWorkerService().

• Not only this DiagnosticsTelemetryModule adding to DI and also we need to configure it's heartbeat interval/module using the below snippet:

services.TryAddSingleton<ITelemetryModule, DiagnosticsTelemetryModule>();
                    services.ConfigureTelemetryModule<DiagnosticsTelemetryModule>((mod,opt) => mod.HeartbeatInterval = TimeSpan.FromSeconds(30));
                    services.AddApplicationInsightsTelemetryWorkerService();

• The TelemetryConfiguration.Active is not recommended because Worker service is new SDK, its not touching .active or any other static singletons.

Where can I track it?

After Deploying, Look for "HeartbeatState" in customMetrics.

Note:

• Disabling DiagnosticsTelemetryModule will cause the following settings to be ignored: EnableHeartbeat, EnableAzureInstanceMetadataTelemetryModule, EnableAppServicesHeartbeatTelemetryModule.
• Enable Azure Monitor from the Portal.
