.NET 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 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+ runtime metrics

The process and .NET runtime metrics are collected by the metrics instrumentation. The metrics are prefixed with process.* and process.runtime.*.

.NET 8 runtime metrics

OTel semantic process and .NET runtime metrics are collected by the metrics instrumentation. The metrics are prefixed with process.* and process.runtime.*.

.NET 9+ runtime metrics

OTel semantic process and .NET runtime metrics are collected by the metrics instrumentation. The metrics are prefixed with process.* and dotnet.*.

.NET Framework 4.6.2+ application metrics

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

.NET 8+ application metrics

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