This dashboard provides comprehensive monitoring of host-level system metrics for Kubernetes environments, offering detailed visibility into CPU usage, memory utilization, disk I/O, network performance, and filesystem usage across all nodes in your cluster.
📝 Note
To use this dashboard, you need to set up the data source and send telemetry to SigNoz. Follow the Host Metrics guide to get started.

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
