Health information for a node

Fields§

§status: NodeStatus

Current health status

§last_healthy_ms: u64

Last successful health check timestamp (unix millis)

§failure_count: u32

Consecutive failure count

§success_count: u32

Consecutive success count

§avg_response_ms: f64

Average response time in milliseconds

§cpu_percent: f32

CPU usage percentage

§memory_percent: f32

Memory usage percentage

§active_connections: u32
