Bandwidth Monitors

Bandwidth Monitors display live upload and download throughput for a router, gateway, network interface, or other device. They appear in the Main View between the Internet Dashboard (above) and Latency Monitors (below).

What can be monitored

A Bandwidth Monitor can pull data from:

• Your internet router via UPnP (auto-discovered during First Time Setup) or SNMP.
• A local network interface on your Mac (Wi-Fi, Ethernet, USB tethering, VPN).
• SNMP-enabled network devices (switches, access points, NAS, servers) added manually via Configuration Assistant.

Section header

The header bar above the monitors holds controls for the whole Bandwidth Monitors section:

From left to right:

Control	Description
Show / Hide	Collapses or expands the entire Bandwidth Monitors section.
New Monitor	Adds a new Bandwidth Monitor via the Configuration Assistant.
Counts	Summarises monitors by status, with a colored dot for each: green for Active, yellow for Warning, red for Error, and grey for Disabled.
Split Graph	Toggles between a single combined graph and a separate graph for each monitor.
Shared Y Axis	Puts every monitor’s graph on the same vertical scale so throughput can be compared directly.
Open History	Opens the History view for the monitors in this section.

Reading the graph

Each monitor shows live upload (↑) and download (↓) throughput, plus a graph of recent activity. Hover over an expanded graph to reveal the graph toolbar below.

A single monitor packs more detail than it first appears:

Along the top of each monitor, from left to right:

• Disclosure triangle — expands or collapses the monitor’s graph, leaving just the title and throughput visible.
• Status light — a colored dot showing the monitor’s current state: green for Active, yellow for No Data or Initializing, red for Error, and grey for Disabled.
• Symbol — the icon representing device or interface being monitored. This can be configured in Settings → Bandwidth Monitor.
• Name — the monitor’s label. Set this in Settings → Bandwidth Monitor.
• Download speed — current inbound throughput, marked with a down arrow (↓).
• Upload speed — current outbound throughput, marked with an up arrow (↑).

The graph itself adds a couple more details:

• Fuel gauges — the slim bars beside the monitor title fill up to show current upload and download speed relative to the device’s maximum bandwidth. Enable or disable them from Settings → Display.
• Maximum bandwidth lines — the dashed lines mark the maximum inbound and outbound bandwidth for the device, with optional numeric labels. This shows the configured theoretical maximum bandwidth for the given device or interface. Configure the maximum bandwidth under Bandwidth Options.

Configuring

Add, remove, and customize Bandwidth Monitors from Settings → Bandwidth Monitor, where you can adjust polling intervals, units, colors, alert thresholds, and more.

Graph toolbar

The same graph toolbar appears on both Bandwidth Monitors and Latency Monitors. Hover over an expanded graph to reveal it:

From left to right:

Control	Description
Zoom out	Zooms the graph out, showing more time.
Zoom in	Zooms the graph in, showing less time.
Share	Shares the graph via Mail, Messages, AirDrop, etc.
History	Opens the History view for this target.
Settings	Opens the settings for this monitor in Settings → Bandwidth Monitor.
