# DRE Settings

> Control automatic investigation, re-investigation sensitivity, and the default severity for manually logged Incidents.

Open **DRE → Settings** to control when DRE investigates and how it treats new evidence. These settings affect RCA behavior; they do not disable Pulse detection or Incident creation.

The page is one scroll with a **Behaviour** group and, when your workspace has it, a **Policies** group. Runbooks are not here — they live on their own [Runbooks](/guide/incident/runbooks) page.

## Re-investigation sensitivity

Choose how readily DRE starts a new investigation when an existing Incident receives more evidence:

| Option       | Behavior                                                              |
| ------------ | --------------------------------------------------------------------- |
| Conservative | Re-investigate only when the new evidence strongly changes the case.  |
| Balanced     | Use the recommended balance between responsiveness and repeated work. |
| Sensitive    | Re-investigate with a lower threshold for meaningful new evidence.    |

## DRE auto-investigates

Use the On Duty toggle to control automatic RCA.

* **On:** eligible Pulse-created Incidents can start RCA automatically.
* **Off:** Pulse continues to detect, correlate, and create Incidents, but analysis waits until a person clicks **Investigate**.

Turning On Duty back on applies to future routing decisions. Incidents created while it was off do not automatically form a backlog of RCA work. A person can always start RCA manually.

## Default manual severity

Choose the initial severity for newly logged manual Incidents, from **Critical**, **High**, **Medium**, **Low**, or **Info**. The default is **Medium**. The person logging the Incident can change it before creation.

## Policies

Some workspaces also show a Policies section. Policies control which proposed operational actions DRE can allow, pause for approval, or deny. If the section is not available, use the runbook effects and workspace approval controls exposed to your account.
