These custom configurations let you control how data is collected and recorded. We've included various examples: ## Configuring your OTEL Tracing * [Configure OTEL Tracer](/docs/ax/observe/tracing/configure/configure-otel-tracer) * [Batch vs Simple Span Processor](/docs/ax/observe/tracing/configure/batch-vs-simple-span-processor) * [Advanced OTEL Tracing Examples](/docs/ax/observe/tracing/configure/advanced-tracing-otel-examples) ## Customize Spans Regardless of whether you use automatic or manual instrumentation, you can customize your spans with additional attributes that capture relevant context: * [Add inputs and outputs](/docs/ax/observe/tracing/configure/input) * [Add evals](/docs/ax/observe/tracing/configure/evals-on-traces) * [Add prompt templates & variables](/docs/ax/observe/tracing/configure/instrumenting-prompt-templates-and-prompt-variables) * [Add attributes, metadata and tags](/docs/ax/observe/tracing/configure/add-attributes-metadata-and-tags) * [Add events, exceptions and status](/docs/ax/observe/tracing/configure/add-events-exceptions-and-status-to-spans) * [Add cost tracking](/docs/ax/observe/tracing/configure/add-cost-tracking) * [Add latent metadata](/docs/ax/observe/tracing/configure/logging-latent-metadata) ## Sensitive Data Handling When working with **sensitive data**, you can also enforce data protection by masking or redacting span attributes: * [Mask span attributes](/docs/ax/observe/tracing/configure/masking-span-attributes) * [Redact sensitive data from traces](/docs/ax/observe/tracing/configure/redact-sensitive-data-from-traces) If you don’t find what you’re looking for here, check out the [OTEL](https://opentelemetry.io/docs/) docs.
