Migrate from the SignalFx Tracing Library for Ruby 🔗

The SignalFx Ruby tracing library is deprecated and will reach End of Support on September 30th, 2023. Replace it with the agent from the Splunk Distribution of OpenTelemetry Ruby.

The agent of the Splunk Distribution of OpenTelemetry Ruby is based on the OpenTelemetry Instrumentation for Ruby, an open-source project that uses the OpenTelemetry API.

Read the following instructions to learn how to migrate to the Splunk Ruby OTel agent.

Compatibility and requirements 🔗

The Splunk Distribution of OpenTelemetry Ruby requires Ruby 2.5 and higher. See OpenTelemetry Ruby compatibility and requirements.

Migrate to the Splunk Distribution of OpenTelemetry Ruby 🔗

To migrate from the SignalFx Tracing Library for Ruby to the Splunk Distribution of OpenTelemetry Ruby, follow these steps:

  1. Remove the tracing library packages. See Remove the SignalFx Tracing Library for Ruby.

  2. Deploy the Splunk Distribution of OpenTelemetry Ruby. See Deploy the Splunk Ruby agent.

  3. Migrate your existing configuration. See Migrate settings for the Splunk Ruby OTel agent.

Note

Semantic conventions for span names and attributes change when you migrate. For more information, see Migrate from SignalFx Smart Agent to the Splunk Distribution of OpenTelemetry Collector.
