Effective traffic analysis of the industry standard sFlow

 

 

 

i NetFlow is a protocol for collecting, aggregating and recording traffic flow data in a network. NetFlow data provide a more granular view of how bandwidth and network traffic are being used than other monitoring solutions, such as SNMP. NetFlow was developed by Cisco and is embedded in Cisco’s IOS software on the company’s routers and switches and has been supported on almost all Cisco devices since the 11.1 train of Cisco IOS Software.

Productivity is the Alpha and the Omega

When heavily-utilized computer networks become slower or crash, corporate productivity is impaired, often resulting in financial losses.

Networks which quickly and accurately process and exchange data are an absolute must, and can guarantee trouble-free workflows and the proper “time to market” of your product. For high-traffic networks, it is therefore a good idea to monitor data traffic and available bandwidth. To do so, you can use the industry standard sFlow, and monitor professionally with PRTG.

 

sFlow technology

sFlow works similarly to Cisco’s NetFlow, and was first introduced by HP. It stands for “sampled flow,” and uses statistical samples of data traffic to ensure scalability for interfaces with large amounts of data.

sFlow technology puts little strain on the CPU load and data line, and allows for the collection of detailed data. Because PRTG fully supports sFlow Version 5 (the most common version), switches and routers supplying data via sFlow can be monitored with a great deal of ease. PRTG offers several possibilities for individually processing the bandwidth consumption data that is gained as a result of its monitoring, as well as for the data’s subsequent presentation. PRTG lets you configure your dashboard so you can keep a constant eye on your data consumption!

 

Detect causes of traffic

With 24/7 network monitoring, you can identify the major causes of traffic and eliminate bottlenecks. PRTG’s data analysis even allows for suspicious traffic to be detected. The combination of sFlow and PRTG effectively prevents downtime and provides valuable indicators which will enable you to optimize the overall performance of your network.

With PRTG, everyone will work with peace of mind.

How sFlow monitoring works

The sFlow protocol is an industry standard for monitoring data packets in computer networks. Bandwidth utilization data is recorded and summarized inside the router or switch of the device (these processes are referred to as “flows”), while relevant information is sent as UDP packets to PRTG for statistical processing and presentation. With sFlow, you won’t analyze all your data traffic, but only every nth data packet. This method is called “sampling,” and is obligatory for sFlow. With NetFlow, sampling can be configured as required.

When it comes to monitoring bandwidth in high-traffic networks, flow monitoring is recommended the most, for in general it uses very little CPU and can provide in-depth data analysis while consuming minimal amounts of bandwidth.

To use sFlow monitoring, your network device must support sFlow version 5 and be configured to allow flow data to be sent to PRTG.
