System Monitoring

The System Dashboard is your real-time telemetry center for monitoring server health. It provides live metrics, historical charts, hardware inventory, diagnostic tools, and automated alert rules — all in a wide-format layout designed for at-a-glance server awareness.

Key features

Overview metric strip

At the top of the System Dashboard, a row of KPI tiles gives you an instant snapshot of server health:

These tiles update in real time. A status indicator in the page header shows whether telemetry streaming is active.

Bandwidth history

The bandwidth history section occupies the largest area of the System Dashboard. It displays time-series charts showing network throughput for your selected interface, powered by vnStat.

Key capabilities:

• Time range selection — Choose from predefined ranges or use the timeseries player controls to scrub through historical data
• Multiple interfaces — If your server has more than one network interface, select which one to chart from the command bar
• Chart interaction — Hover over data points to see exact values. The chart updates in real time when viewing the current time window

The health sidebar next to the bandwidth chart shows a compact summary of CPU, memory, and storage health with status badges.

CPU and memory panels

Below the bandwidth chart, dedicated CPU and memory panels display:

• Real-time utilization — Live-updating charts showing current CPU and memory usage
• Historical data — Time-series charts with the same range controls as the bandwidth section
• Per-core breakdown — CPU charts show individual core utilization when expanded
• Thermal data — CPU temperature readings when hardware sensors are available

System inventory

The system inventory panel displays your server’s hardware and software details:

• Hardware — CPU model, core/thread count, total memory, disk capacity
• Operating system — Distribution, kernel version, hostname
• Service uptime — How long the server has been running since last reboot
• Mount points — Configured storage mount points with usage breakdown

Software RAID monitoring

On servers with Linux software RAID (mdadm) arrays, the System Dashboard displays a dedicated RAID panel with live array status, member disk health, and rebuild progress. The panel appears automatically when RAID arrays are detected — no configuration is required. On servers without software RAID, the panel is hidden entirely with zero overhead.

Array overview

Each detected array shows key identification and status information:

Drive SMART health

For each member disk in an array, the panel collects S.M.A.R.T. data to assess drive health. SMART data refreshes every 5 minutes (independently of the 15-second array status updates) because the underlying smartctl probes are resource-intensive. Both SATA/SAS and NVMe drives are supported.

Health indicators

The RAID panel uses a color-coded health system derived from array state, SMART data, and mismatch counts:

Rebuild progress

When an array is rebuilding, resyncing, reshaping, or running a consistency check, the panel displays a progress indicator with:

• Percentage complete — how far the operation has progressed (0–100%)
• Speed — current throughput of the rebuild operation (e.g., 185000K/sec)
• Estimated time remaining — projected finish time based on current speed

The array state changes to “rebuilding” and the health status is set to “critical” for the duration of the operation, ensuring visibility.

System users

This section shows Linux user accounts currently connected to the server and their active sessions. Each entry displays the username, terminal, connection time, and source IP address.

Health cards

The health cards provide deeper analysis for three key resource areas:

• CPU Health — Load averages, governor settings, per-core utilization, and thermal status
• Memory Health — Detailed breakdown of used, cached, buffered, and available memory plus swap usage
• Storage Health — Per-mount usage, inode consumption, and growth trends

Each card includes a status indicator (healthy, warning, or critical) based on current utilization thresholds.

Quick actions

The quick actions section provides one-click access to common system operations:

Monitor rules

Monitor rules let you set up automated alerts when server resources cross defined thresholds. You can create rules for:

• CPU usage — Alert when CPU exceeds a percentage for a sustained period
• Memory usage — Alert when RAM usage crosses a threshold
• Disk usage — Alert when storage consumption reaches a warning level

Each rule can trigger configurable actions, such as sending a notification to admins.

APT runner

The APT Runner is a slide-out panel for managing operating system package updates:

• Pending updates — View a list of available system package updates
• Apply updates — Run package updates with live output streaming
• Update history — Review previously applied updates

Diagnostics

The diagnostics section allows you to generate a comprehensive diagnostic bundle that captures system state, logs, and configuration information. This bundle is useful when troubleshooting issues with the QuickBox support team.

Click Generate Diagnostics to create the bundle, which can then be downloaded as a file.
