## What Fleet Management checks

Fleet Management continuously monitors your collectors and checks three things. Based on these checks, each collector receives a health status.

| Check             | Question it answers                                             |
|-------------------|-----------------------------------------------------------------|
| **Reachability**  | Can Fleet Management communicate with the collector?            |
| **Alerts**        | Are any user-created alerts firing for this collector?          |
| **Config errors** | Did the collector load the remote configuration without errors? |

## Health status indicators

| Status      | Meaning                                               | Action                  |
|-------------|-------------------------------------------------------|-------------------------|
| **Healthy** | All checks passing, collector is operational          | None needed             |
| **Warning** | Collector is inactive or has non-critical alerts      | Investigate soon        |
| **Error**   | Collector has a critical alert or configuration error | Investigate immediately |

> **The traffic light system:** At a glance, you can see which collectors need attention. Green = fine. Yellow = investigate soon. Red = investigate now.
