SolarWinds Lab Episode #76 (May 2019) - Joe vs. the NetFlow Volcano

Level 18

May 15, 2019

Whether you’re curious if flow monitoring might be helpful, or you’ve been coalescing IPFIX streams of network-activity goodness for years, IT’s reliable, old hand has learned a few new tricks. In this episode, Head Geeks Patrick Hubbard and Leon Adato are joined by Principal Product Manager for NetFlow Traffic Analyzer, Joe Reves, to revisit the basics and rediscover why network engineers use flow monitoring in the first place. They'll discuss how it’s configured, and examine the differences between NetFlow, J-Flow, sFlow, and other protocols. Find out when to use basic flow monitoring, traffic sampling, 95th percentiles, and traffic-based rules to see what’s really happening on your network. Times have changed and, believe it or not, flow monitoring has, too.

About the Author
In my sordid career, I have been an actor, bug exterminator and wild-animal remover (nothing crazy like pumas or wildebeasts. Just skunks and raccoons.), electrician, carpenter, stage-combat instructor, American Sign Language interpreter, and Sunday school teacher. Oh, and I work with computers. Since 1989 (when you got a free copy of Windows 286 on twelve 5¼” floppies when you bought a copy of Excel 1.0) I have worked as a classroom instructor, courseware designer, desktop support tech, server support engineer, and software distribution expert. Then about 14 years ago I got involved with systems monitoring. I've worked with a wide range of tools: Tivoli, Nagios, Patrol, ZenOss, OpenView, SiteScope, and of course SolarWinds. I've designed solutions for companies that were extremely modest (~10 systems) to those that were mind-bogglingly large (250,000 systems in 5,000 locations). During that time, I've had to chance to learn about monitoring all types of systems – routers, switches, load-balancers, and SAN fabric as well as windows, linux, and unix servers running on physical and virtual platforms.
