Deprecation of Coralogix Serilog 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 Serilog SDK on June 30, 2026.

The Coralogix Serilog 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 a proprietary SDK 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 following Coralogix-maintained Serilog SDK is deprecated:

  • Coralogix.Serilog

This SDK may currently be used in:

  • .NET applications that use Serilog with a Coralogix sink
  • Applications configured with Coralogix-specific endpoints and credentials
  • CI/CD pipelines that install Coralogix NuGet packages

After the effective date, this SDK will no longer be supported or maintained.

What you need to do

Migrate to OpenTelemetry for Serilog

Replace the Coralogix Serilog SDK with OpenTelemetry .NET instrumentation.

What will happen after June 30, 2026?

  • The Coralogix Serilog 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.
