How to Collect .NET Application Logs with OpenTelemetry

Observability is essential for maintaining and scaling modern applications. With .NET 8, Microsoft has enhanced support for observability using OpenTelemetry. In this post, we explore how to monitor .NET 8 applications logs with SigNoz , an open-source observability platform, using the OpenTelemetry Protocol (OTLP) exporter. OpenTelemetry in .NET 8 OpenTelemetry (OTel) is a vendor-neutral standard for collecting telemetry data (logs, metrics, and traces) from cloud-native applications. In .NET 8, OpenTelemetry is natively supported through the System.Diagnostics namespace and enhanced via the OpenTelemetry NuGet packages. It allows for: Automatic instrumentation of ASP.NET Core and HTTP clients Manual instrumentation with activities and tags Exporters to send data to backend systems like SigNoz An image displaying .NET integration with SigNoz flow .NET 8 supports native logging correlation with OpenTelemetry, making it easier to link logs with traces automatically.
