Compatibility and requirements

Make sure that you have the correct requirements for the OpenTelemetry C++ instrumentation. See Prerequisities.

Migrate to the OpenTelemetry instrumentation for C++

To migrate from the Splunk instrumentation for C++ to the OpenTelemetry instrumentation for C++, follow these steps:

1. Deactivate the Splunk instrumentation for C++.

2. Install and activate the OpenTelemetry instrumentation for C++. See Instrument your C++ application for Splunk Observability Cloud.

3. Update your configuration settings.

4. Restart the server and application.

Deactivate the Splunk instrumentation for C++

Because the Splunk instrumentation for C++ is a wrapper for the OpenTelemetry instrumentation, there isn’t an official process for uninstalling.

Instead, you can remove the Splunk Distribution of OpenTelemetry C++ repository and its submodules. When you install and configure your application for OpenTelemetry C++, remove any code that uses the Splunk distribution and replace it with new code for OpenTelemetry C++ instrumentation.

Change configuration settings

Options passed through splunk::OpenTelemetryOptions are no longer supported.

If you passed any options through splunk::OpenTelemetryOptions, change these options to environment variables.

For example, imagine you had the following option in your C++ code:

splunk::OpenTelemetryOptions options = splunk::OpenTelemetryOptions().WithServiceName("my-service")

To change the option to an environment variable, delete the code and run the following command:

export OTEL_SERVICE_NAME="my-service"
