Health Checks

Duende supports periodic health checks for monitoring daemon status.

Configuration

[health_check]
enabled = true
interval = "30s"  # Check every 30 seconds
timeout = "10s"   # Timeout for each check
retries = 3       # Failures before unhealthy

Implementation

#![allow(unused)]
fn main() {
async fn health_check(&self) -> HealthStatus {
    // Check dependencies
    if !self.db.is_connected() {
        return HealthStatus::unhealthy("Database disconnected");
    }

    // Check internal state
    if self.queue.len() > 10000 {
        return HealthStatus::degraded("Queue backlog");
    }

    // Return healthy with score
    HealthStatus::healthy(5)
}
}
