This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.
pmacct is a small set of multi-purpose passive network monitoring tools. It
can account, classify, aggregate, replicate and export forwarding-plane data,
ie. IPv4 and IPv6 traffic; collect and correlate control-plane data via BGP
and BMP; collect infrastructure data via Streaming Telemetry. Each component
works both as a standalone daemon and as a thread of execution for correlation
purposes (ie. enrich NetFlow with BGP data).
