Network monitoring tools are a critical aspect of today’s network-driven world. There are different industry standards to monitor the traffic that passes through networks, and sFlow is one such standard. sFlow is used for monitoring high speed switched networks and gives complete visibility into the use of networks.
Users can glean rich information using this standard, that in turn, can eventually lead to performance optimization, protection against security threats, understanding bandwidth usage and more.
Since sFlow is an important industry standard, many companies have come up with tools that collect and analyze this network information.
Here’s a look into the top sFlow collectors & analyzers for traffic and bandwidth analysis.
Here’s the Top sFlow Collectors & Analyzers of 2018:
