LMTV LIVE | Distributed Network Monitoring with Raspberry Pi (with Panos Vouzis of NetBeez)



YouTube LIVE start time: Wednesday, August 9, 2017 - 9: 30 AM (PST)


Netbeez Single-board computers, like the Raspberry Pi or Odriod, are getting widespread adoption within the network engineering community thanks to their computational power (approximately 1 GHz) and low cost (less than $50 per unit). As a result, more and more companies are deploying these devices within their enterprise networks and using them as monitoring sensors to collect analytics on network performance, wireless networks, and cloud services.

Panos Vouzis is a cofounder of NetBeez which provides network performance monitoring designed for network managers primarily interested in early fault detection and quick troubleshooting of complex wide area networks.

Distributed network monitoring with IP SLA (by Stefano Gridelli)

Distributed network monitoring with IP SLA!

The Cisco IP Service Level Agreement (IP SLA) technology is nothing new to network engineers. In its basic operations, IP SLA enables routers and switches to use a protocol like ICMP to check end-to-end response time between the device itself and a destination IP device.

As stated in the Cisco IP SLA configuration guide, “IP SLAs uses active traffic monitoring—the generation of traffic in a continuous, reliable, and predictable manner—for measuring network performance”.

One of the most common uses of IP SLA is configuring floating static routes to determine the preferred active link or, in HSRP, to assure that the router with the highest priority to take over that gateway function has access to the default route.

What to Look for in a Network Monitoring Tool (by Stefano Gridelli)


What-to-look-for-in-a-seller


Before working on NetBeez with my team, I was a system administrator for many years and then a network engineer. In both positions, I had to select, configure, and maintain a variety of network monitoring tools for various purposes: server monitoring, network management and monitoring, and application troubleshooting. This experience gave me a clear understanding of how monitoring tools differ.

If you are in the market for a network monitoring tool, you will quickly notice that there are a lot of choices. Probably hundreds of them, and choosing the right one is not easy .. Following are some things to consider when selecting a network monitoring tool.

First, you must be aware that there are three major categories of network monitoring tools: SNMP-based, flow-based, and active/synthetic.

Distributed Command Line Interface for EASY Distributed Testing! (by Panos Vouzis)

Distributed Command Line Interface - Easy Distributed Testing!

In the best case scenario, you will need to troubleshoot a networking issue at the same location you are. This is rarely the case though. In most cases, you will receive a ticket about an issue affecting a user at a remote location. In these cases, the network engineer's best friends are command line utilities such as ping, traceroute, and iPerf.

Let’s take the scenario in which a user in Austin opens a ticket  about how he can’t access an application that runs at your data center in Scottsdale, which is where you are located. A ping and a traceroute from Scottsdale to Austin gets you started with troubleshooting, but what you really need is the ping and traceroute from Austin towards your data center in Scottsdale.

And if you are able to walk an employee in Austin through the steps to run a ping and a traceroute command on a console and send you the results, it would most likely take you 20 minutes. This is about 19 minutes longer than it would take for you to just run the tests yourself if you’d had access to the machine. Actually this is what many folks do. Today with low-cost platforms such as the Raspberry Pi, this is easier that it used to be.

Deploying and managing dozens of these units can be a hassle. In addition, if you need to troubleshoot multiple locations at the same time, it is cumbersome to log in to one unit, run a ping and traceroute, and then repeat this several times.
