FlowSphera 1.4.0 release notes

Path analysis — a new page next to Through device: traffic across several devices instead of one.
- Choose a device as the Point of View: its layer-3 neighbours are drawn around it (1, 2 or 3 hops deep), each link as a ribbon (from / to the internet, internal) with the interface and address at both ends. A device with no layer-3 neighbour cannot be chosen.
- Neighbours come from the same data as Through device: interfaces of two devices in one subnet (Settings → Devices → Interfaces) and, without any addresses set, from the records themselves — one device's own addresses and inside networks seen on another's interface, and the same conversation recorded by both. A tunnel between two sites (GRE, IPsec) is found this way too.
- Every link shows what each end sent and the other received: a red dashed line marks a link whose far end sends no NetFlow, or a gap where much less arrived than was sent.
- Path: enter a source and a destination (an address or a network) and get the hops in order — the interfaces each device used, NAT, other exits, the share of conversations each device recorded, and where the path is not seen whole. ⇄ shows the reply direction.
- API: GET /api/topology?pov=&depth=, GET /api/path?src=&dst=.
