Dashboard

Dashboard

Dashboard
The Dashboard displays real‑time metrics for the selected server. The interface is organized into tabs, each dedicated to a specific group of parameters.

To conserve system resources, a lazy loading mechanism is implemented: collapsed (inactive) tabs do not fetch or update any data. This reduces network and server‑side overhead, which is especially beneficial when monitoring multiple servers or handling a large set of metrics.

Below you will find a detailed description of each tab and other dashboard capabilities.

Metrics

Metrics

This section displays the following metrics for the selected server:

  • CPU Usage – Current processor load as a percentage (e.g., 0.6%).
  • Memory – RAM usage in the format used / total MB (e.g., 346 / 1986 MB).
  • Load Average – Average system load over 1, 5, and 15 minutes. A value like 0.05 indicates virtually no pending processes.
  • CPU Cores Usage – Visual representation of each CPU core’s load (percentage or graphical).
  • CPU History (20 samples) – Chart showing overall CPU usage over the last 20 measurement points (helps detect short‑term spikes).
  • Memory Usage – Memory usage chart including:
    • Used RAM
    • Free RAM
    • Swap usage

Disk I/O Performance

Disk I/O Performance

This section displays real‑time I/O activity for all disks attached to the server.

Parameters:

  • Active – name of the active disk (if multiple disks are active, they are shown accordingly)
  • Read / Write – current read and write speed in MB/s
  • Queue – I/O operation queue length (a high value may indicate a disk performance bottleneck)
  • Total Read / Total Write – total amount of data read and written since monitoring started (in MB)

Important feature:

  • Newly connected disks appear in this section automatically
  • When a disk is disconnected, it automatically disappears from the list

Physical Disks & Partitions

Physical Disks & Partitions

This section displays information about all physical disks attached to the server and their partitions.

Disk parameters:

  • SMART – disk self‑test status (e.g., PASSED / OK or error)
  • Disk name and model – e.g., sda - VMware Virtual S
  • Total disk size – full disk capacity
  • Total Usage – total used space on the disk in percentage and volume (used / total)

Partition parameters (shown as a tree with indentation):

  • Partition name – e.g., sda1, sda2
  • Filesystem type – ext4, swap, unknown, etc.
  • Mount point – path where the partition is mounted (e.g., /, [SWAP])
  • Used – used space in percentage and as used / total

Display features:

  • Partitions are visually grouped under their parent physical disk
  • Swap partitions show [SWAP] as the mount point
  • If filesystem information is unavailable, unknown is shown

RAID Arrays

RAID Arrays

This section displays information about all software or hardware RAID arrays detected on the server.

Parameters for each array:

  • Array name – e.g., md0, md1
  • RAID type – array level (RAID 0, 1, 5, 10, etc.)
  • Total size – available array capacity
  • Status – array state (active, degraded, recovering, etc.)
  • Devices – number of active devices in the array (active / total expected)
  • Device list – names of disks belonging to the array

Color status indicators:

  • Green / ✓ icon – array is healthy and operating normally
  • Red / error indication – the array has errors (e.g., failed disk or sync failure)
  • Yellow – the array is in a write‑protected state. This typically occurs after a reboot if the array was not mounted automatically. In this state, writing to the array is impossible until it is manually mounted or automatically recovered.

LVM Volumes

LVM Volumes

This section displays information about all Logical Volume Manager (LVM) volumes on the server. The interface is divided into two main areas: Volume Groups and Logical Volumes.

Volume Groups:

  • Group name – e.g., vg_data, vg_data2
  • Total size – full capacity of the volume group
  • Used – used space within the group
  • PV – number of Physical Volumes in the group
  • LV – number of Logical Volumes in the group
  • Usage percentage – e.g., 100% used

Logical Volumes:

  • Volume name – e.g., lvhome1
  • Parent group – the volume group the logical volume belongs to (e.g., vg_data)
  • Size – capacity of the logical volume
  • FS – filesystem type (e.g., ext4, xfs)
  • Mount status – whether the volume is mounted (e.g., Not mounted, /mnt/data)

Overall status:

  • The top line of the section shows the general LVM state (e.g., ✓ Active)

Network Interfaces

Network Interfaces

This section displays information about all network interfaces available on the server.

Parameters for each interface:

  • Interface name – e.g., enp1s0, wlp2s0
  • IP address – current IPv4 address of the interface (if no address is assigned, N/A is shown)
  • RX (Receive) – total amount of data received since monitoring started (in MB)
  • TX (Transmit) – total amount of data transmitted since monitoring started (in MB)
  • MAC address – physical address of the network interface

Display features:

  • Interfaces without an assigned IP address show N/A in the IP field
  • Wireless interfaces (wlp*) may display additional information when connected
  • RX/TX values accumulate from the start of monitoring or since the interface came up

System Information

System Information

This section displays basic information about the server’s status and configuration.

Parameters:

  • Uptime – continuous system operation time since the last boot (format: days hours:minutes:seconds)
  • Hostname – network name of the server (e.g., bkp01.local)
  • Kernel – operating system kernel version (e.g., 4.9.0-13-marvell)
  • Processes – total number of running processes on the system
  • Version – version Mini Bucket (e.g., 3.5.5)

Purpose:

These parameters allow quick assessment of:

  • How long the server has been running without a reboot
  • Server identification on the network
  • Kernel compatibility and update level
  • Overall load (indirectly, via process count)
  • Current software version in use

Top Menu (upper right corner)

Top Menu (upper right corner)

In the upper right corner of the dashboard there is a menu button providing access to additional functions and sections.

Menu items:

  • Diag Utils – monitoring utilities and testing tools. Allow you to perform system diagnostics, check hardware status, and identify potential issues.
    More details: https://mini-bucket.ru/wiki/knowledge-base/diagnose/diagnose/
  • System Checker – checks installed packages and configuration for proper Mini Bucket operation with your server. Helps ensure all dependencies are satisfied and the system is configured correctly.
  • License – license agreement. Displays the software terms of use.
  • Donation – link to the project support page. Allows you to provide financial assistance to the developers.
  • Refresh – forces an immediate update of all metrics on the dashboard without waiting for the next automatic refresh cycle.
