Saisei IPFIX Support

Managing a network without having the necessary tools for visibility and control is similar to playing Russian roulette. You know a problem is going to occur, you’re just not sure when or how to find it. With the volume of mobile, cloud, and Internet of Things traffic increasing on a daily basis, visibility into network usage, user behavior, and application performance becomes critical for providers to monitor and optimize. Packets and ports are no longer the metrics by which the network is judged—the future is about flows. No wonder more and more vendors are asking the question, “What is IPFIX?”and then choosing to export it. Saisei Networks (pronounced Sī•sā:, Japanese for “Rebirth”) is one of them.

Tracking Network Traffic in Real-Time Data Granularity

Tracking Network Traffic in Real-Time Data Granularity

I talk to customers daily about forensic data granularity as it relates to collecting and reporting on NetFlow exports. I am often asked about how we store data and what is the resource impact on collecting flow data.

What is Data Granularity?

Data granularity is the level of depth represented by the data collected. High granularity means that you get a minute by minute detail accounting level of the transactions traversing the network. Lower granularity zooms out into more of a summary view of the data and transactions.

Why is this important?

Cisco ASR 9000 Configuration NetFlow Guide

Posted in Cisco Performance Monitoring, netflow configuration, sFlow on February 2nd, 2016 by Jeff

Cisco ASR 9000 Configuration Guide

One of the best parts about working in Tech Support for a company that analyzes NetFlow, is that I get the opportunity to work with a wide variety of vendors and models. Today most vendors are supporting at least one form of NetFlow. Whether that’s version 5, version 9 or IPFIX. No matter what version of NetFlow, we’re awarded the ability to capture and analyze the traffic on our network in almost real-time. Today I wanted to take a look at the founders of the NetFlow protocol, Cisco, and their Cisco ASR 9000 configuration.

One important thing to note about the ASR9k, is it supports sampled NetFlow. There’s a bit of controversy surrounding sampled NetFlow however. Some people prefer it because it alleviates the possible performance penalty incurred by enabling NetFlow exports. Others would prefer getting a more complete picture of their network traffic. Mainly this will depend on the traffic volume of your network. It is important to note though, that sample NetFlow will substantially decrease the CPU utilization needed to account for NetFlow packets. That being said, let’s dig into getting your Cisco ASR 9000 configured! Read more »

Splunk Competitors

Our IT department recently went through the process of evaluating Splunk competitors such as Elasticsearch and a couple of other vendors. Although we had our list of required features, the more pricey solutions demonstrated clear benefits over the cheaper more affordable systems.
