TelemetrySelector.Community 1.0.0-RC.1

TelemetrySelector.Community

The Community edition of the TelemetrySelector library.

TelemetrySelector.Community is a source-available .NET library focused on improving control over Application Insights telemetry filtering, sampling, and selection.

The project is designed for community users who need more control over telemetry volume, telemetry relevance, and Application Insights costs in ASP.NET Core and .NET applications.

Why TelemetrySelector.Community Exists

Modern applications often generate excessive telemetry.

In many systems:

• low-value telemetry creates noise
• ingestion costs become expensive
• default sampling strategies are too generic
• filtering logic becomes repetitive across projects
• tooling is not designed to be configured on the flight

TelemetrySelector.Community was created to provide:

• more intelligent telemetry filtering
• selective telemetry retention
• configurable decision rules
• hability to change configuration during runtime without restart
• better control over telemetry pipelines
• extensibility for custom selection logic

Main Goals

• Reduce unnecessary telemetry
• Improve signal-to-noise ratio
• Help reduce Application Insights ingestion costs
• Provide customizable filtering behavior
• Support ASP.NET Core and .NET applications
• Allow rule-based telemetry selection
• Support advanced telemetry processing scenarios

Features

• Configurable telemetry filtering
• Rule-based telemetry selection
• Extensible filtering pipeline
• Support for custom logic
• Integration with Application Insights
• ASP.NET Core integration
• Flexible runtime behavior
• Designed for high-volume environments

Installation

Install-Package TelemetrySelector.Community

or

dotnet add package TelemetrySelector.Community

##Note

We suggest you to install

• the TelemetrySelector.Community.Extensions.DependencyInjection library for dependecy injection
• the TelemetrySelector.Community.Serialization.Json for json serialization

Both libraries extend on TelemetrySelector.Community and provide additional functionaly that is commonly required by applications.

Basic Example

builder.Services.AddTelemetrySelector();

...

app.UseMiddleware<TelemetryItemTagger>();

See the ASP.NET Core web app created as an example on how to use, configure and synchronize multiple application instances.
