Tracing Overview

Sending Traces

Langtrace SDK allows you to group related operations together using the `@with_langtrace_root_span` decorator for Python or `WithLangTraceRootSpan` for Typescript.

Grouping Traces

Grouping Operations

The Langtrace SDK gives you the ability to pass user feedback from your application as scores for measuring accuracy.

Passing User Feedback

Pass User Feedback

Learn how to attach user ids to traces in Langtrace. You can use the `withAdditionalAttributes` or `inject_additional_attributes` function to pass user ids. This can inturn be used within Langtrace for filtering and grouping traces.

Attach User Id

Attach User IDs to Traces

Learn how to attach prompt ids and prompt versions to traces in Langtrace. You can use the `withAdditionalAttributes` or `inject_additional_attributes` function to pass prompt ids / versions. This can inturn be used within Langtrace for filtering and grouping traces.

Attach Prompt Id / Version

Attach Prompt IDs and Versions to Traces

You can add additional attributes to traces in Langtrace by simply wrapping your code with the `withAdditionalAttributes` or `inject_additional_attributes` function. This will add the specified attributes to the trace spans.

Additional Attributes

Add Additional Attributes to Traces

You can disable tracing for specific functions per vendor by passing the `disable_tracing_for_functionss` parameter in `Langtrace.init` function. The `object` should have the vendor name as the `key` and an `array` of **function names** as the `value`.

Disable Function Tracing

Disable Tracing For Functions

Disable Tracing For Specific Vendors

Disable Tracing For Prompts & Completions

Learn how to ett custom span names to traces in Langtrace. You can use the `inject_additional_attributes` function to set custom span names to traces. This name will be appended to the operation name and will be identifed as the name of the span in the trace.

Set Custom Span Name

Set custom span names to traces

Langtrace SDK allows you to pass a session ID to traces to filter them later.

Filtering Traces by Session ID

Langtrace lets you store and version prompts, making it easy to manage and reuse them across your applications.

Manage Prompts

Langtrace lets you store and version Zod schemas for tool calling, making it easy to manage and reuse them across your applications.

Langtrace has a model playground where you can interate on your prompts with different models and model settings to see how they perform.

Model Playground

Langtrace allows you run evaluations on annotated datasets and get insights on the performance of your application.

Evaluations

Langtrace allows you compare evaluations run on different models to understand the performance of your application across different models.

Compare Evaluations

Langtrace allows you to create tests and manually annotate your traces to evaluate the performance and create datasets for running evaluations.

Annotations

Langtrace supports a variety of LLMs, Frameworks and Vector databases.
