# Manage a trace

> Compare traces side-by-side, share traces publicly, and view server logs from the trace view in LangSmith.

From the trace view, you can [compare two traces](#compare-traces) side-by-side,[ share a trace publicly](#share-a-trace), and [view the server logs](#view-server-logs) associated with a trace execution.

## Compare traces

You can start comparing traces from two areas in the [UI](https://smith.langchain.com):

1. From the **Runs** tab in the **Tracing** projects view, select checkboxes next to the traces you would like to compare. Then, select **Compare Runs** at the bottom of the page to open a side-by-side comparison view.
2. When you're viewing a trace, select the more <Icon icon="dots-vertical" /> menu to navigate to **Compare**. This will open the trace run table. Select the trace you want to compare against the original trace. The side pane will open with both traces selected in a side-by-side comparison view.

To stop comparing, close the pane or click on **Stop comparing** in the upper right-hand side of the pane.

## Share a trace

<Warning>
  **Sharing a trace publicly will make it accessible to anyone with the link. Make sure you're not sharing sensitive information.**

  If your [self-hosted](/langsmith/self-hosted) or [hybrid](/langsmith/hybrid) LangSmith deployment is within a VPC, then the public link is accessible only to members authenticated within your VPC. For enhanced security, we recommend configuring your instance with a private URL accessible only to users with access to your network.
</Warning>

To share a trace publicly:

1. Open any trace in the [UI](https://smith.langchain.com).
2. Click the **Share** button in the more <Icon icon="dots-vertical" /> menu at the top of the trace view.
3. In the dialog that appears, copy the public link.

Shared traces are accessible to anyone with the link, even without a LangSmith account. They can view the trace but not edit it.

To unshare a trace, use either of the following methods:

1. Open the shared trace, click **Public** in the toolbar at the top of the trace view, then click **Unshare** in the dialog.
2. Go to **Settings** → **Shared URLs** to view all publicly shared traces in your organization. Click **Unshare** next to the trace you want to unshare.

## View server logs

<Note>
  Viewing server logs for a trace only works with the [Cloud SaaS](/langsmith/cloud) and [fully self-hosted](/langsmith/self-hosted) deployment options.
</Note>

When viewing a trace that was generated by a run in LangSmith, you can access the associated server logs directly from the trace view.

In the trace view, use the **See Logs** button in the top right corner, next to the **Run in Studio** button.

Clicking this button will take you to the server logs view for the associated deployment in LangSmith.

The server logs view displays logs from both:

* **Agent Server's own operational logs**: Internal server operations, API calls, and system events
* **User application logs**: Logs written in your graph with:
  * Python: Use the `logging` or `structlog` libraries.
  * JavaScript: Use the re-exported Winston logger from `@langchain/langgraph-sdk/logging`:

    ```javascript theme={null}
    import { getLogger } from "@langchain/langgraph-sdk/logging";

    const logger = getLogger();
    logger.info("Your log message");
    ```

When you navigate from the trace view, the **Filters** box will automatically pre-fill with the Trace ID from the trace you just viewed, so you can quickly filter the logs to see only those related to your specific trace execution.
