Struct GpuMemoryDashboard 

pub struct GpuMemoryDashboard { /* private fields */ }

GPU Memory Dashboard for monitoring and visualization.

Provides real-time GPU memory tracking with allocation history, per-kernel usage, and memory pressure alerts.

Example

use ringkernel_core::observability::GpuMemoryDashboard;

let dashboard = GpuMemoryDashboard::new();

// Track an allocation
dashboard.track_allocation(
    1,
    "input_queue",
    65536,
    GpuMemoryType::QueueBuffer,
    0,
    Some("processor_kernel"),
);

// Get current stats
let stats = dashboard.get_device_stats(0);
println!("GPU 0 utilization: {:.1}%", stats.utilization());

// Generate Grafana panel JSON
let panel = dashboard.grafana_panel();
