.NET runtime and system metrics

The metric names and attributes are subject to change due to unstable semantic conventions and current non-conformance by the OTel .NET implementation.

This feature is supported by APM .NET Library versions 6.1.0 and above when OpenTelemetry is enabled. See SolarWinds Observability | Install the .NET APM Library with OpenTelemetry Support (Beta) for how to enable OpenTelemetry. OpenTelemetry can be enabled for .NET Framework applications 4.6.2+ and .NET applications 8+.

.NET Framework 4.6.2+ application metrics

OTel semantic Asp.Net, HttpClient, .NET runtime, and process metrics are collected by the metrics instrumentation. The metrics are prefixed with http.server, httpclient.*, and process.*.

.NET 8+ Application Metrics

OTel semantic Asp.Net Core, HttpClient, .NET runtime, process, database client metrics (Npgsql and SqlClient), and NServiceBus metrics are collected by the metrics instrumentation. The metrics are prefixed with http.server, httpclient.*, process.*, db.client.* and nservicebus.*.
