Dashboard

Dashboard

The Dashboard is your central hub for monitoring UAVcast-Pro's status and your Raspberry Pi's system health. It provides real-time information about services, system resources, and network connectivity.

Overview​

The Dashboard displays several information cards that update in real-time:

  • System Information - Raspberry Pi model, OS version, and hostname
  • Memory Usage - RAM utilization with percentage and available memory
  • Storage - SD card usage and available disk space
  • Network Statistics - Bandwidth usage for all active network interfaces
  • Service Status - Real-time status of all UAVcast-Pro services
  • CPU Metrics - Temperature, voltage, and throttling status

System Information Card​

Displays essential system details:

  • Device Model: Raspberry Pi model (e.g., Raspberry Pi 4 Model B)
  • OS Version: Current Raspberry Pi OS version
  • Hostname: Network hostname of your device
  • Uptime: How long the system has been running
  • CPU Architecture: Confirms 64-bit operation (aarch64)

Memory Usage​

Real-time RAM monitoring:

  • Used Memory: Current memory consumption
  • Total Memory: Total available RAM
  • Percentage: Memory utilization percentage
  • Visual Meter: Progress bar or graph showing usage
Performance

If memory usage consistently exceeds 80%, consider:

  • Closing unnecessary applications
  • Disabling unused services
  • Upgrading to a Raspberry Pi with more RAM

Storage Information​

SD card space monitoring:

  • Used Space: How much storage is consumed
  • Available Space: Free space remaining
  • Total Capacity: SD card size
  • Percentage: Storage utilization
Low Storage

UAVcast-Pro requires free space for:

  • Log files
  • Video recordings (if enabled)
  • Database operations
  • System updates

Maintain at least 1GB of free space for optimal operation.

Network Statistics​

Real-time bandwidth monitoring for all network interfaces:

  • Interface Name: eth0 (Ethernet), wlan0 (WiFi), usb0 (Modem), zt0 (ZeroTier), etc.
  • Upload Speed: Current data transmission rate
  • Download Speed: Current data reception rate
  • Total Uploaded: Cumulative data sent since boot
  • Total Downloaded: Cumulative data received since boot

Statistics update every 10 seconds by default.

Service Status​

Real-time status of UAVcast-Pro services:

Each service shows a status indicator:

  • 🟢 Green: Service running normally
  • 🔴 Red: Service stopped or error
  • 🟡 Yellow: Service starting/stopping

CPU Metrics​

Temperature Monitoring​

Displays current CPU temperature with color-coded warnings:

  • Green (< 60°C): Normal operation
  • Yellow (60-75°C): Elevated temperature
  • Orange (75-80°C): High temperature
  • Red (> 80°C): Critical - throttling likely
Overheating

If CPU temperature consistently exceeds 75°C:

  • Ensure proper ventilation
  • Add a heatsink or cooling fan
  • Avoid direct sunlight
  • Check case airflow

Voltage and Throttling Detection​

The dashboard monitors power supply health:

  • Under-voltage Detected: Power supply cannot provide sufficient voltage
  • CPU Throttling: Performance reduced due to heat or power issues
Power Supply Issues

Under-voltage indicates an inadequate power supply. This can cause:

  • System instability
  • Crashes and reboots
  • SD card corruption
  • Service failures

Solution: Use a quality 5V/3A power supply or UBEC. Do not power from servo rail.

Throttling Icons​

  • 🟢 Green: No throttling, optimal performance
  • 🔴 Red: Active throttling or under-voltage detected
