Trend Prediction in Network Monitoring Systems

Posted on 03/04/09 19 Comments

Following up on Real-Time Predictive Analytics for Web Servers I thought we should “move up a level” and look at various open network monitoring platforms with trend prediction capabilities. Our web server management team picked Zabbix to monitor a busy production server and then we started to look into adding predictive analytics afterwards.   Alberto recommended [...]

Apache Mahout: Real-Time Decisioning in the MapReduce Framework

Posted on 01/14/09 2 Comments

Here is a bit of good news for the complex event processing space.  Folks on the Apache Mahout developers mailing list are showing an accelerated interest in topics related to real-time decision-making, starting with a Markov decision process. The Hidden Markov Model (HMM) is listed under “non map-reduce algorithms” on the Mahout wiki.  The developer’s [...]

The Motivation Behind Adaptive Analytics and CEP

Posted on 10/11/08 17 Comments

This is a continuation of The Genesis of Complex Event Processing: Asymmetric Capabilities and CEP, Event Noise and Asymmetric Event Processing where I have been discussing the motivation behind CEP and adaptive analytics in cyberspace. Around the same time that Professor Luckham and his team was working on CEP applications in network management and security [...]
