When you start an investigation from an Error Tracking issue, Bits analyzes the error, including its stack trace and related telemetry. If you set up [Source Code Integration](https://docs.datadoghq.com/source_code.md), Bits also analyzes your source code. It then reports the likely root cause and the impact of the issue. To list all investigations triggered from Error Tracking, open [Investigations](https://app.datadoghq.com/bits-ai/investigations) and filter on Source: Error Tracking Issue. ## Prerequisites{% #prerequisites %} - To view investigations, you need the [Bits Investigations Read permission](https://docs.datadoghq.com/account_management/rbac/permissions.md#bits-ai). To start investigations, you need the [Bits Investigations Write permission](https://docs.datadoghq.com/account_management/rbac/permissions.md#bits-ai). - To let Bits read the code that was running when the error occurred, set up [Source Code Integration](https://docs.datadoghq.com/source_code.md). Bits can investigate without source code access, but the root cause analysis is less precise. - To generate code fixes, set up [Bits Code](https://docs.datadoghq.com/bits_ai/bits_code/setup.md), which needs write access to your repository and the [Bits Code Write permission](https://docs.datadoghq.com/account_management/rbac/permissions.md#bits-ai). ## Investigate an Error Tracking issue{% #investigate-an-error-tracking-issue %} To investigate an Error Tracking issue with Bits Investigation: 1. In the [Error Tracking Explorer](https://app.datadoghq.com/error-tracking), click an issue to open the issue panel. 1. On the Review tab, click Investigate this issue in the Bits Investigation banner. {% image source="https://docs.dd-static.net/images/error_tracking/bits_investigation/start_investigation.7449d689ec86fb69d45da7d4c5345ac8.png?auto=format&fit=max&w=850 1x, https://docs.dd-static.net/images/error_tracking/bits_investigation/start_investigation.7449d689ec86fb69d45da7d4c5345ac8.png?auto=format&fit=max&w=850&dpr=2 2x" alt="The Bits Investigation banner on the Review tab of an Error Tracking issue, with the Investigate this issue button." /%} While the investigation runs, the banner shows its progress and who triggered it. An investigation usually takes a few minutes. 1. When the investigation completes, review the findings in the banner: - **Root cause**: The most likely cause of the error, based on the evidence Bits gathered. - **Impact**: How the error affects your users and services. For a completed investigation, the banner displays the root cause and impact side by side: {% image source="https://docs.dd-static.net/images/error_tracking/bits_investigation/investigation_summary.cfeb16f2e17991118bf65244a9f70eb3.png?auto=format&fit=max&w=850 1x, https://docs.dd-static.net/images/error_tracking/bits_investigation/investigation_summary.cfeb16f2e17991118bf65244a9f70eb3.png?auto=format&fit=max&w=850&dpr=2 2x" alt="The Review tab of an Error Tracking issue, showing the root cause and impact found by Bits Investigation." /%} If the available data is insufficient to support a conclusion, Bits marks the investigation as inconclusive. 1. (Optional) To see the full investigation, click View Investigation in the banner. The investigation page shows the conclusion, suggested next steps, and a timeline of the evidence: {% image source="https://docs.dd-static.net/images/error_tracking/bits_investigation/investigation_report.c45653ecee0c4b3c1264787ae2bc943e.png?auto=format&fit=max&w=850 1x, https://docs.dd-static.net/images/error_tracking/bits_investigation/investigation_report.c45653ecee0c4b3c1264787ae2bc943e.png?auto=format&fit=max&w=850&dpr=2 2x" alt="The Bits Investigation page for an Error Tracking issue, showing the conclusion, root cause, impact, a suggested next step, and the timeline." /%} To ask follow-up questions about the investigation, use Bits Chat. For more information, see [Chat with Bits Investigation](https://docs.datadoghq.com/bits_ai/bits_investigation/chat_bits_investigation.md). For more information about how Bits reaches its conclusion and how to explore the investigation steps, see [How Bits investigates](https://docs.datadoghq.com/bits_ai/bits_investigation/investigate_issues.md#how-bits-investigates) in Investigate Issues. ## Fix the issue in code{% #fix-the-issue-in-code %} When the root cause is in your code, Bits Investigation uses [Bits Code](https://docs.datadoghq.com/bits_ai/bits_code.md) to generate a fix. The fix appears as a suggested next step on the investigation page, with a summary of the change and its diff. A code fix next step includes actions to open a pull request or keep working on the fix: {% image source="https://docs.dd-static.net/images/error_tracking/bits_investigation/code_fix_next_step.15e76eedd708a4355eac6ee1b5b34178.png?auto=format&fit=max&w=850 1x, https://docs.dd-static.net/images/error_tracking/bits_investigation/code_fix_next_step.15e76eedd708a4355eac6ee1b5b34178.png?auto=format&fit=max&w=850&dpr=2 2x" alt="A suggested next step with a code fix generated by Bits Code, showing a summary, a diff, and the Create PR and View in Bits Code buttons." /%} From the next step, you can: - Click Create PR to open a pull request with the fix. - Click View Full Diff to review all changed files. - Click View in Bits Code to iterate on the fix in a Bits Code session. Bits Code never merges changes automatically. Review and test generated code before you merge it. ## Further reading{% #further-reading %} Additional helpful documentation, links, and articles: - [Learn about Bits Investigation](https://docs.datadoghq.com/bits_ai/bits_investigation.md) - [Chat with Bits Investigation](https://docs.datadoghq.com/bits_ai/bits_investigation/chat_bits_investigation.md) - [Generate code fixes with Bits Code](https://docs.datadoghq.com/bits_ai/bits_code.md) - [Set up Source Code Integration](https://docs.datadoghq.com/source_code.md)
