Network Weathermap NG

Draw your network as a live map: nodes for your sites and devices, links for the circuits between them, and colors that change with real traffic. Network Weathermap NG turns any Grafana time series — interface throughput, utilization, error rates — into a classic network weathermap, built and edited entirely inside the Grafana panel editor.

If you have used PHP Network Weathermap, the concepts (nodes, links, color scales) will feel immediately familiar.

What you can do with it

• NOC wall displays — a single at-a-glance map of your backbone, WAN, or campus network, colored by live utilization.
• WAN and backbone monitoring — see both directions of every circuit independently, so an asymmetric saturation stands out.
• Capacity planning — color links by percentage of provisioned bandwidth and spot the circuits trending toward saturation.
• Incident triage — node status coloring flags down devices, and per-link dashboard links jump straight to the detailed dashboard for that circuit.
• Historical review — scrub the timeline slider to replay link values across the selected time range and see when traffic shifted.

How it works

Each link has two sides, A and Z, and each side is driven by one query from the panel:

• A side shows traffic flowing A → Z (for example, bits sent on the A device's interface).
• Z side shows traffic flowing Z → A (for example, bits received on the A device's interface).

Every side gets a bandwidth (a fixed number or another query), and the link segment is colored by the color scale — either percentage of bandwidth or absolute thresholds.

Nodes are the endpoints: label them, give them icons (networking, server, database, and computer icon sets are bundled), and optionally color them from a status metric.

Setting up a map

1. Add the panel to a dashboard and add one query per link direction. Give each query a clear name or legend — you pick queries by name in the editor.
2. Open the panel options and expand Edit Weathermap.
3. Under Nodes, add your nodes, then drag them into position on the canvas (a snappable grid with alignment guides is available).
4. Under Links, add a link, choose its A and Z nodes, and assign each side its query and bandwidth.
5. Under Color Scale, define your thresholds — green/yellow/red utilization bands, or absolute values.
6. Save the dashboard. The map updates with every dashboard refresh.

Feature highlights

Links

• Independent A/Z sides with per-side queries, bandwidth, labels, and direction labels (for example Inbound / Outbound).
• Multiple parallel links between the same two nodes.
• Curved routing with VIA points — double-click a link on the canvas to add one, right-click to remove.
• Value display modes: last, average, minimum, maximum, or 95th percentile over the dashboard time range, with configurable decimal places and units.
• Optional dynamic stroke width, animated traffic flow, and gradient coloring.
• Port/interface labels so the physical circuit is visible on the map.

Nodes

• Icons with adjustable size, padding, and constant spacing.
• Status coloring from a metric: color the node border, background, or both, with configurable value-to-color threshold mappings.
• Per-node dashboard links (open in the same or a new tab) for drill-down.

Tooltips

• Hovering a link shows both directions with inbound/outbound graphs.
• Add extra metric rows to link and node tooltips — errors, discards, latency, packet loss, or anything else you can query.

Panel

• Pan, zoom, and multi-select with mouse or trackpad (macOS-compatible controls).
• Timeline slider to replay link values across the selected time range.
• Custom background color or image, adjustable fonts, and a movable, resizable color-scale legend.
• One-click SVG export of the map.

Data sources

The panel reads standard Grafana data frames, so it works with Prometheus, InfluxDB, Graphite, Zabbix, MySQL/PostgreSQL, and any other data source that returns time series. Each link side expects a single numeric series.

Requirements

Grafana 11.0.0 or later.
