# System Status

<figure><img src="/files/RIUeHlEPKxnsgEClvdL7" alt=""><figcaption></figcaption></figure>

The system status tab appears in the bottom panel of Vozilla. It gives real-time feedback on the state of the system to help debug issues with setup.

The dots have 4 possible states:

* Green
  * No issues were detected
* Amber
  * Warning: something isn't functioning as expected
  * This could be a blocking issue, or might be something you can ignore depending on you specific setup
  * Hover to read the warning message
* Red
  * Critical: the system will not function properly without this missing field
  * You need to address this if you want to fly the drone
* Gray
  * No data is available
  * Most likely this data comes from a different data source than the one you are connected with

### Data Sources

There are two information sources: **mavlink** and the **Theseus Edge API**

#### Theseus Edge API

This is a service that runs on the edge device. You need to be connected to the edge device over ethernet to be able to access this data source.

#### MAVLink

If you connect to the flight controller over mavlink in vozilla (see [MAVLink](/gcs-software/mavlink.md#connecting-with-vozilla)) you'll be able to see a limited number of the status indicators.

* [VPS Diag](/gcs-software/mavlink/monitoring-vps-health-over-mavlink.md)
* Vozilla Mav
  * shows [heartbeat information](https://mavlink.io/en/messages/common.html#MAV_STATE) of cyclops and the flight controller

### User customization

You can customize the view to display only the status fields relevant to you're connection mode or use case.
