What This Dashboard Monitors

This dashboard tracks essential host system metrics to help you:

Monitor System Resources: Track CPU and memory usage across Kubernetes hosts
Disk Performance: Monitor disk I/O operations, usage, and performance metrics
Network Activity: Observe network traffic, bandwidth utilization, and interface statistics
Filesystem Management: Monitor disk space usage, available capacity, and filesystem health
Infrastructure Health: Identify performance bottlenecks and resource constraints at the host level

Metrics Included

Overview Section

CPU Used: Current CPU utilization value
Allocatable CPU: Total CPU resources available for allocation
Memory Used: Current memory consumption in GiB
Allocatable Memory: Total memory available for allocation in GiB

Resources Section

CPU Usage Chart: Real-time CPU utilization breakdown by type (user, idle, system, softirq, wait, steal, interrupt, irq, nice)
Memory Usage Chart: Memory consumption breakdown by type (used, free, cached, slab_reclaimable, buffered, slab_unreclaimable)
CPU Usage by Namespace: CPU utilization per Kubernetes namespace
Memory Usage by Namespace: Memory consumption per Kubernetes namespace
CPU Usage by Pod: CPU utilization per individual pod
Memory Usage by Pod: Memory consumption per individual pod

System Section

System Load Average: System load averages over 1min, 5min, and 15min intervals

Network Section

Network Usage (Bytes): Network traffic in bytes for transmit and receive operations
Network Usage (Packet/s): Network traffic in packets per second
Network Errors: Network error rates and failed transmissions
Network Drops: Dropped network packets
Network Connections: Active network connections by TCP state (TIME_WAIT, ESTABLISHED, LISTEN, etc.)

Disk Section

System Disk I/O (Bytes Transferred): Data transfer rates for read and write operations
System Disk Operations/s: Disk operations per second for various devices
Disk Operations Time: Time taken for disk operations
Queue Size: Disk I/O queue size

Filesystem Section

File System Usage Table: Tabular view showing device, mountpoint, state, and filesystem type
File System Inode Usage Table: Inode utilization showing device, mountpoint, state, and type
