NetworkIndicator Plugin for Noctalia

A compact Noctalia bar widget that displays current network upload (TX) and download (RX) activity, with optional live throughput values and a hover-activated graph panel.

Features

TX/RX Activity Indicators: Separate icons for upload (TX) and download (RX).
Active/Idle Coloring: Icons switch between "active" and "silent" colors based on a configurable traffic threshold.
Optional Throughput Values: Displays formatted TX/RX speeds as text (shown only when the bar is spacious and horizontal).
Vertical and Horizontal Layouts: Stack TX/RX values on the left of the arrows, or place them side by side with arrows centered in between.
Unit Formatting: Automatically switches between KB/s and MB/s, or can be configured to always display MB/s.
Custom Font: Override the default font for speed values, with optional bold and italic styles.
Network Graph Panel: Hover over the widget to open a live graph showing RX and TX history from the system monitor.
Theme Support: Uses Noctalia theme colors by default, with optional custom colors.
Configurable Settings: Provides a comprehensive set of user-adjustable options.

Installation

Configuration

Access the plugin settings in Noctalia to configure the following options:

Icon Type: Select the icon style used for TX/RX: arrow, arrow-bar, arrow-big, arrow-narrow, caret, chevron, chevron-compact, fold.
Show Values: Display formatted TX/RX speeds as numbers. Automatically hidden on vertical bars and when using "mini" density.
Force Megabytes: Always display values in MB/s instead of switching to KB/s at low traffic levels.
Horizontal Layout: Place TX and RX values side by side instead of stacked.
Minimum Width: Set a minimum width for the widget to prevent resizing when values change.
Content Margin: Horizontal padding on both sides of the widget content.
Show Active Threshold: Set the traffic threshold in bytes per second (B/s) above which TX/RX is considered "active".
Vertical Spacing: Adjust the spacing between the TX and RX elements.
Font Size Modifier: Scale the text size.
Icon Size Modifier: Scale the icon size.
Custom Font: Override the default font with any installed font, with bold and italic options.
Custom Colors: When enabled, configure TX Active, RX Active, RX/TX Inactive, Text, Font, and Background colors.

Technical Details

The widget reads SystemStatService.txSpeed and SystemStatService.rxSpeed; the polling interval is determined by that service.
The graph panel uses SystemStatService.rxSpeedHistory and SystemStatService.txSpeedHistory with NGraph from the Noctalia Shell.
The panel opens on hover with a short delay and closes automatically when the cursor leaves the widget.
