FlowSphera 1.9.5 release notes

Templates belong to their domain

17 October 2026
  • Templates belong to their domain (core 1.5.0). A NetFlow v9 template id is unique only within its source ID, an IPFIX one within its observation domain: line cards of a router or virtual systems of a firewall may each define template 256 with another layout. FlowTrack kept one template per id and device, so such devices could have their records read with another card's layout. Now templates, the sampling rate sent in options records and the duplicate detection by the direction field are kept per domain; when only one domain sends the sampler options (some devices send them under another source ID than the flows), that rate applies to all. Templates saved by earlier versions serve any domain until the device resends them (within minutes). Devices with one domain, like FortiGate and MikroTik, count exactly as before.
