Networking 101: What is a VLAN?

The idea of a VLAN, or Virtual Local Area Network, is simple enough, right? It’s hard to imagine any work in a modern networking/IT space without having encountered, set up, or managed a VLAN. Well if that’s all you needed to know about VLANs, we’d be done here, but there’s a bit more to it. To cover our bases: In most modern networks the primary purpose of the LAN is to provide connectivity to a wider network, most notably the internet.

Synthetic web tests - Moving up the stack

In this short explainer and demo, Kentik's Phil Gervasi shows how Kentik is moving up the stack to monitor application activity on the network. Phil explains the differences between proactive and passive network monitoring and demonstrates three new synthetic tests that relate to app performance monitoring. Kentik's suite of application-focused synthetic tests give you proactive visibility into application activity on your network. Using the HTTP test, Page Load test, and Synthetic Transaction Monitoring, you can monitor a user's digital experience and troubleshoot problems as they happen.

Log Forwarding with HAProxy and Syslog
