## 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                                                  |
|-------------------|----------------------------------------------------------------------|
| **Check-in**      | Has the collector contacted Fleet Management in the last 30 minutes? |
| **Alerts**        | Are any user-created alerts firing for this collector?               |
| **Config errors** | Did the collector load its remote configuration without errors?      |

> Fleet Management doesn’t create alerts. It surfaces active alerts you’ve created in your stack.

## Health status indicators

| Status      | Color  | Meaning                                                     | Action                  |
|-------------|--------|-------------------------------------------------------------|-------------------------|
| **Healthy** | Green  | All checks passing, collector is operational.               | None needed             |
| **Warning** | Yellow | Non-critical alert, or the collector hasn’t checked in.     | Investigate soon        |
| **Error**   | Red    | Critical alert, or a remote configuration error.            | Investigate immediately |
| **Unknown** | Gray   | Collector hasn’t reported any telemetry yet (no heartbeat). | Confirm it started      |

> **A quick glance tells you what needs attention.** Green is fine, yellow needs a look soon, and red needs investigating now. Gray means a collector hasn’t reported in yet, so check that it started and can reach Grafana Cloud.
