11 # Maps and Globe
12
13 Four geographic views, all driven by the same aggregation engine as the Sankey and Time-Series:
14
15 - **Country map** — countries connected by edges weighted by traffic
16 - **State map** — same, at state/province granularity
17 - **City map** — same, at city level (down to street-level granularity, depending on your GeoIP database)
18 - **Globe** — a 3D view of city-level connections rendered as arcs over the globe
19
20 Use these to spot geographic patterns at a glance — unexpected destinations, asymmetric traffic, CDN routing.

23
24 Country map with top-N pushed to 500, so practically every country with traffic shows up. Edge thickness is bandwidth aggregated per country pair.
25
26 ## How they work
27
28 For each map view, the dashboard:
29
30 1. Forces a specific aggregation. You don't pick `group_by` for these views — the view picks for you.
31 2. Runs the aggregation across your time range and filters.
32 3. Renders the top-N (25/50/100/200/500) results as edges on the map.
33 4. Same aggregation drives the side-panel list of countries / cities. The list and the map are two views of the same data.
34
35 The forced aggregations are:
36
37 | View | Forced group-by |
38 |---|---|
39 | Country map | `SRC_COUNTRY`, `DST_COUNTRY` |
40 | State map | `SRC_COUNTRY`, `SRC_GEO_STATE`, `DST_COUNTRY`, `DST_GEO_STATE` |
41 | City map | `SRC_COUNTRY`, `SRC_GEO_STATE`, `SRC_GEO_CITY`, latitude, longitude (source + destination) |
42 | Globe | Same as city map |
43
44 Edge width is proportional to your sort metric (bytes or packets). The geographic coordinates needed to draw cities and arcs come from the response itself — they're already enriched into each flow record by the time the dashboard renders. You don't need a separate city-coordinates database in the dashboard.
45
46 ## Country and state vs city / globe
47
48 The country map and state map can use the rollup tiers. They're cheap over long time windows.
49
50 The city map and the globe **need raw-tier data**. City, latitude, and longitude are dropped from the rollup tiers (1m / 5m / 1h) to keep cardinality manageable. So:
51
52 - Country / state map over the last 30 days — fine, uses the 1-hour tier.
53 - City map over the last 30 days — likely empty. Raw-tier retention defaults to its own 10GB / 7d limits; busy collectors often hit the raw-tier size cap before 7 days.
54
55 If your city map looks empty over a long window, try the country map first to confirm data is arriving, then narrow the time range until the city map fills in.
56
57 ## Tooltips
58
59 Hover over a country, state, city, or arc to see a tooltip. The tooltip shows the same fields as the underlying row — endpoints, byte and packet counts. Click does **not** drill down to a different view; the maps are read-only with respect to navigation. To change perspective (e.g., "show me traffic for this country only"), use the filter ribbon to add a `SRC_COUNTRY` or `DST_COUNTRY` selection.

63 State map with top-N at 500, zoomed over the US. The tooltip on the link between Attica (Greece) and California shows bidirectional traffic — bytes and packets in each direction.

67 City map with top-N at 500, zoomed over Europe. Dozens of European cities appear connected by edges weighted by bandwidth.

73 ## Things to know
74
75 ### GeoIP is required
76
77 Without a GeoIP database, country / state / city / coordinate fields are empty and the maps are blank. Native packages include a stock DB-IP database — see the [DB-IP integration card](/src/crates/netflow-plugin/integrations/db-ip_ip_intelligence.md) and the [Enrichment Intel Downloader](/docs/network-flows/intel-downloader.md). Source builds need the operator to run the downloader once.
78
79 ### CDN traffic shifts
80
81 Your traffic to a SaaS provider may resolve to one country today and another tomorrow because the CDN's routing changed. This is normal CDN behaviour, not a security incident. ASN-based aggregation is more stable for cloud / CDN traffic than country-based — see the [Anti-patterns page](/docs/network-flows/anti-patterns.md) "Geographic firewall of shame".
82
83 ### Bidirectional traffic on the map
84
85 Bidirectional traffic between two endpoints produces two separate flow records (one per direction) and renders as two distinct edges (A→B and B→A). The two directions are usually asymmetric in volume — for example, a download is large in one direction and small in the other. To see only one direction, filter on a specific source or destination.
86
87 ### Globe vs City Map
88
89 The globe and city map render the same data with the same table beneath. The 2D city map is best for precise comparisons within a continent. The 3D globe is best when distance and great-circle paths matter — transcontinental traffic, undersea cable corridors, intercontinental CDN routing. Pick the one that fits the question.
90
91 ## What controls are available
92
93 - **Time range** — Netdata's global time picker
94 - **Filters** — facet selections + autocomplete + full-text search
95 - **Top-N** — 25 / 50 / 100 / 200 / 500
96 - **Sort by** — bytes or packets (determines edge weight and the side-list ranking)
97 - **Group-by** — locked to the view-specific aggregation; not user-configurable for maps
98
99 ## Things that go wrong
100
101 - **City map empty.** Time range exceeds raw-tier retention. Narrow the range, or use country/state map for a wider view.
102 - **Ireland or Singapore showing up unexpectedly.** Probably AWS/GCP/Azure shifting CDN routing. ASN-based aggregation is more stable.
103 - **A whole country disappears.** Your filter excluded it. Check the filter ribbon.
104 - **No data on globe but city map works.** Both should fail or succeed identically — they consume the same response. If they diverge, that's a dashboard bug worth reporting.
