Your switch doesn't support flow? We show how you can monitor it anyway!

Flow based monitoring (NetFlow, sFlow, jFlow, IPFIX...) is a powerful method to get detailed information about the traffic on your switches and firewalls. It not only delivers data about the sheer amount of traffic, but also what kind of traffic it is, where it comes from and where it goes to. Using flow monitoring you can get top lists of users, connections or protocols. However, not every switch, router, or firewall supports flow protocols. Most flow protocol supporting devices are expensive high-end series, while older devices or budget series don't support it. You can find more information about flow monitoring at the Paessler manual https://www.paessler.com/manuals/prtg/flow_monitoring.

A Step-by-Step Guide: Figure Out Who’s Hogging Your Bandwidth

One of the most common (and frustrating!) questions a sysadmin needs to answer is: who is hogging all my bandwidth?

The network is slow, users are complaining, and your internet connection is at 100% (again...).  You need to figure out who or what is hogging all the bandwidth, and you need to do it fast. In this article, I'll explain the different methods that are available in different situations, and how to use SNMP, RMON, flow and packet sniffing to track down the culprits.

If You Use SNMP a Lot and Don't Know What SMI Is, Then Read This!

I wouldn't be surprised if you told me you have fallen in love with SNMP. Because it is so universal in network administration. Because it is a powerful all-round talent that supplies you with nearly every kind of information you need about whatever network device. Surely you love SNMP, if you know how to set it up on your machine. And if you know what OIDs are and what you need the MIB (files) for. And if your setup is fine, SNMP works reliably (at least it should), and you can live happily ever after.

How to use Windows’ built-in IP Address Management Server

One of the more general requirements placed on every administrator is that of always maintaining an overview.
