Real-Time Predictive Analytics for Web Servers

We recently made the decision to move to Zabbix to monitor one of our busy production Apache web servers.  One of the things we need to do in the future is try to predict system outages and take corrective actions before the system actually goes down.
For example, recently a busy server experenced an outage that [...]

Twenty Four CEP Public Presentations on SlideShare

For archiving purposes, I have uploaded 24 public CEP presentations that I presented over an 18 month period at various conferences from March 14, 2006 to September 21, 2007.  These presentations can be viewed here.  For example, my first public CEP presentation:

So far, I have placed [...]

TIBCO BusinessEvents 3.0

I was pleased to read the Paul Vincent’s post, TIBCO BusinessEvents 3.0.    TIBCO has always had a forward thinking vision for distributed computing and this release of BE 3.0 is another step in the right direction.  TIBCO now has the only commercial-off-the-shelf (COTS) event processing platform on the market that supports distributed event processing, multi-agent [...]

CEP is Not Low Latency Messaging, EAI or ESB

In respose to CEP is Not BPM, BAM, BRE, BRMS or SOA, fellow blogger Mark Palmer posts, Smart Order Routing and CEP - Made for Each Other.   Mark does a good job describing his perspective on smart order routing (SOR), yet his counterpoint that SOR is “complex event processing” is quite unconvincing.
I agree with Mark that SOR is important [...]

The Kum Bai Ya of Event Processing

Kindred spirit Marc Adler mentions being a bit ”turned off” by the sniping back-and-forth in the CEP/EP blog-o-sphere.  This was exactly how I felt in early 2006 when folks were sniping back and forth about SQL standards and event stream processing (ESP).  A group of vendors had created some stream processing engines and all were in “power positioning” mode with the acronyms “ESP” and ”CEP”, hoping to ride [...]

The Bot Hunter: An Event Processing Challenge (Bot or Not)

Recently we penned The Attack of the Spiders from the Clouds where we mentioned how cloud computing infrastructures can be used to stage malicous or accidential network attacks.
Today I challenge our CEP/ESP/EP vendors (or SIs) to create the following solution to detect and block rogue bots on Apache web sites.   I will install and test [...]

CEP is to Architecture as SOA is to Architecture

I am often asked pointed questions (mostly from the stream processing crowd) like, ” What product does CEP?”  Sometime it seems my answer determines the fate of that relationship, as my feet are grilled over the CEP-fire to be beat of jungle drums!  The amount of money I have lost in deals that did not [...]

A Brief Introduction to Blackboard Architectures

A blackboard architecture is a distributed computing architecture where distributed applications, modelled as intelligent agents, share a common data structure called the “blackboard” and a scheduling/control process. The blackboard can be either centeralized or distributed, depending on the requirements and constraints of the application(s).
To solve a complex problem in the blackboard-style, the intelligent [...]
