Server Monitor

The server monitoring feature connects to remote Linux servers via SSH to collect and display real-time system metrics, helping operators quickly assess server health.

Note: Server monitoring only supports Linux remote servers, as it relies on the /proc filesystem and Linux-specific commands. SSH credentials (password or key) are required.

Opening the Monitor

Once an SSH connection is established, the monitoring panel can be opened from the following entry points:

Entry Point	Action
Tab Context Menu	Right-click an SSH terminal tab → Server Monitor
Panel Menu	Click the ... button on the panel header → Open Server Monitor
Sidebar Context Menu	Right-click an SSH connection → Open Server Monitor
Monitor Sidebar	The "Monitor" tab in the left sidebar follows the current active SSH session and shows CPU / memory / network. Click Open Full Monitor to enter the full monitoring page

The server monitor opens as an independent tab alongside terminal, file transfer, and other tabs. It supports drag-to-reorder.

Interface Overview

The monitoring panel is organized into nine tabs — Performance, Processes, Ports, Disks, Network, Services, System Info, Hardware, IPMI — freely switchable via the top tab bar.

Performance

Displays four core metrics — CPU, Memory, Disk, and Network — in real time, refreshing every second, with 60-point line charts showing the last 1 minute of history. Below the CPU / Network / Disk sections are collapsible All Cores / All Network Cards / All Disks detail lists, expandable per core, per network card, and per mount point.

CPU

• Total usage percentage with line chart
• Core count
• Total process count and file handle count
• 1-minute, 5-minute, and 15-minute load averages

Memory

• Total, used, available, and usage percentage
• Cached and buffers usage

Disk

• Root filesystem (/) total, used, and usage percentage

Network

• Receive and transmit rates in bytes per second, calculated from the delta between consecutive samples

Processes

Lists the top 30 processes by CPU usage, refreshing every second.

Feature	Description
Sorting	Sorted by CPU descending by default
Search	Filter by process name, username, or PID
Pause	Click the pause button to stop refresh; click again to resume
Send Signal	The Send Signal button on the right of each row, or open the detail drawer by clicking the row and send from the bottom
Process Detail	Click any process row to open a detail drawer from the right

Process Detail

Clicking a process opens a slide-in drawer with the following information:

• Basic Info — PID, PPID, name, state, thread count, executable path, working directory, full command line, start time
• File Descriptors — Total count with a breakdown by category (files, sockets, pipes, anonymous, devices)
• Virtual Memory — VmRSS, VmSize, VmPeak, VmData, VmStk, VmExe, VmLib
• CPU & Context Switches — CPU ticks, voluntary/involuntary context switch counts
• I/O Statistics — Read/write character and byte counts

Sending Signals

At the bottom of the process detail drawer, you can choose a signal type and send it to the process:

Signal	Number	Description
TERM	15	Graceful termination (default)
KILL	9	Force kill
HUP	1	Hangup, commonly used to reload configuration
INT	2	Interrupt, equivalent to Ctrl+C

A confirmation dialog appears before sending. Force kill (KILL) includes an additional warning.

Ports

Manual refresh. Lists all listening TCP/UDP ports.

Column	Description
Protocol	TCP / UDP
Local Address	Listening address and port
Process	Process PID and name

Disks

Manual refresh. Displays all block devices in a tree structure.

Column	Description
Name	Device name; sub-partitions are indented
Type	disk / part / rom
Size	Total device capacity
Mount Point	Mount path
Used / Usage	Used space and percentage
Media	HDD / SSD / ROM
Filesystem	ext4, xfs, etc.
UUID	Device UUID
Vendor / Model	Hardware information

Network

Manual refresh. Lists all network interfaces.

Column	Description
Name	Interface name (eth0, wlan0, etc.)
State	UP / DOWN
MAC	MAC address
Speed	Interface speed (Mbps)
Type	Physical / Bridge / Bond / Virtual / Loopback
Bond Master	Parent bond interface (if applicable)
IP Addresses	List of bound IP addresses

Services

View and manage system services on systemd hosts:

• The list shows Unit / State / Startup / Description, with search and refresh support
• Each service can be started / stopped / restarted / enabled at boot / disabled at boot / have its logs viewed; dangerous actions require confirmation
• Logs support auto-scrolling; clicking a service row opens its details

System Info

Displays the server's static configuration information along with a live clock:

Category	Content
System	User, uptime, operating system, version, kernel version, hostname, local IP
CPU	CPU model, core count, architecture, CPU frequency, total memory, total disk
Clock	Timezone, host clock (ticking in real time), clock skew (a positive value means the host clock is ahead of the local machine)

Clock skew helps spot hosts whose NTP is unsynchronized or whose clocks have drifted, which is useful when troubleshooting certificate validation and log ordering issues.

Hardware

Displays hardware information in a tree table grouped by category: processors, memory, storage, network, display & audio, buses, and more. Columns are ID / Class / Vendor / Device / Driver / Serial / Capacity / Version, with search support.

IPMI

Collects the server's out-of-band management information via ipmitool, in three parts:

• Device Info — Product, manufacturer, serial number, part number
• Network — IPMI network configuration
• Sensors — Sensor / Value / Unit / Status / Source, with search support

A notice is shown when ipmitool is not installed on the host.
