Download. pavel-odintsov / gist:69108021e4c09599606e. In NetFlow v9 and IPFIX, templates are used instead of a fixed set of fields (like PROTO).See collector.py on how to handle these.. Example: to start the collector run python3 -m netflow.collector -p 9000 -D. This will start a collector instance at port 9000 in debug mode. After you collected some data, the collector exports them into GZIP files, simply named Both Probe and Collector; While capturing packets, turning into flows, and exporting them towards a list of collectors, nProbe can also collect flows sent by remote probes and add them to the flow cache. netflow-collector GitHub Gist: instantly share code, notes, and snippets. Learn more about NetFlow Collectors and modern approaches … NetFlow is a UDP protocol, so one of the things a NetFlow administrator will want to do is monitor how many UDP packets are being dropped by the collector; this can be in indication that the collector host is either not fast enough or that the collector process is not given a high enough scheduling priority (not something that we will concern ourselves right now). In this case, we'd have to investigate, why. Screenshot: Pros: Light weight tool works on Windows. Open Source.

Point your flow exporter to this port on your host and after some time the first ExportPackets should appear (the flows need to expire first). Earlier, I reviewed the open source (OSS) NetFlow collector, as summarized in this article. Now you know udp is reaching to the container. These can be used on the CLI with python3 -m netflow.collector and python3 -m netflow.analyzer. By importing netflow.v1, netflow.v5 or netflow.v9 you have direct access to the respective parsing objects, but at the beginning you probably will have more success by running the reference collector (example below) and look into its code.
