Deprecation of Coralogix NLog SDK
Published: February 16, 2026
Effective: June 30, 2026
Deprecation notice
As part of our continued investment in open standards and long-term observability best practices, Coralogix will deprecate the Coralogix NLog SDK on June 30, 2026.
The Coralogix NLog SDK is deprecated in favor of the OpenTelemetry .NET SDK, which is now the recommended and supported approach for collecting logs, metrics, and traces from .NET applications.
Action is required to ensure continued support and compatibility.
Why this is happening
The observability ecosystem has converged on OpenTelemetry as the industry standard for telemetry collection. Maintaining proprietary SDKs alongside OpenTelemetry creates duplication and limits access to new capabilities.
By standardizing on OpenTelemetry, Coralogix can provide:
- A vendor-neutral, CNCF-backed standard
- Unified collection of logs, metrics, and traces
- Faster access to new ecosystem features and integrations
- Long-term stability and community-driven innovation
- Consistent configuration across languages and platforms
What's affected
The Coralogix-maintained NLog SDK is deprecated.
After the effective date, this SDK will no longer be supported or maintained.
What you need to do
Migrate to OpenTelemetry for .NET
Replace the Coralogix NLog SDK with OpenTelemetry .NET instrumentation.
What will happen after June 30, 2026?
- The Coralogix NLog SDK will no longer be supported.
- No bug fixes, updates, or security patches will be provided.
- Compatibility with newer .NET versions is not guaranteed.
- Support requests related to the deprecated SDK may be declined.
- Existing applications may continue to function, but migration is strongly recommended.
