The Health Check API provides a simple endpoint to verify that the FreeTAKServer REST API is running and responsive.

​
Check API status

Simple health check endpoint that returns the API running status.

​

​
Authentication

This endpoint does not require authentication.

​

​
Use Cases

​
Monitoring and Alerting

Use the /Alive endpoint in your monitoring systems to check if FreeTAKServer is responsive: 
#!/bin/bash
response=$(curl -s -o /dev/null -w "%{http_code}" http://localhost:19023/Alive)
if [ $response -eq 200 ]; then
  echo "FreeTAKServer is running"
else
  echo "FreeTAKServer is down"
fi

​
Load Balancer Health Checks

Configure your load balancer to use /Alive as the health check endpoint to verify backend servers are operational.

​
Docker Health Checks

Include the health check in your Docker configuration: 
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
  CMD curl -f http://localhost:19023/Alive || exit 1

​
Kubernetes Liveness Probe

livenessProbe:
  httpGet:
    path: /Alive
    port: 19023
  initialDelaySeconds: 30
  periodSeconds: 10
For more detailed server status information, use the WebSocket endpoints:
  • serverHealth - Get CPU, memory, and disk usage
  • systemStatus - Get detailed service status information
  • serviceInfo - Get status of all FTS services
These WebSocket endpoints require authentication and provide real-time server metrics.
