This dashboard provides comprehensive monitoring of your virtual machine host-level system metrics, offering detailed visibility into CPU usage, memory utilization, disk I/O, network performance, and filesystem usage across all your VMs.
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 hosts.
- Disk Performance: Monitor disk I/O operations, usage, and performance metrics.
- Network Activity: Observe network traffic, bandwidth utilization, errors, and internet connections.
- Filesystem Management: Monitor disk space usage, available capacity, and filesystem health.
Metrics Included
Overview Section
- CPU Used: Current CPU utilization value.
- Memory Used (Excluding cache/buffer): Current memory consumption.
Resources Section
- CPU Usage Chart: Real-time CPU utilization breakdown by type.
- Memory Usage Chart: Memory consumption breakdown by type.
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 protocol and state.
Disk Section
- System Disk I/O (Bytes Transferred): Data transfer rates for read and write operations.
- System Disk Operations/s: Disk operations per second.
- Queue Size: Disk I/O queue size.
- Disk Operations Time: Time taken for disk operations.
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:
- host.name: Filter by specific host names
Next Steps
- Set Alerts: Configure alerts for high CPU, memory usage, or disk space to ensure system reliability.
