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
Dashboard Variables
This dashboard includes pre-configured variables for filtering:
- k8s.cluster.name: Filter by Kubernetes cluster name
- k8s.node.name: Filter by specific node names
Next Steps
- Set Alerts: Configure alerts for high CPU, memory usage, or disk space to ensure system reliability.
