A Blast from the Past: Processing Patterns for Predictive Business, March 2006

For*readers interested in complex event processing and a few of the challenges the industry faces, here is a presentation from 28 months back called Processing Patterns for Predictive Business.** This presentation was delivered at the first Workshop on Event Processing - Presentations*at IBM Research Labs, Yorktown Heights, March 14-16th 2006.
The same key points of that presentation are still relevant today:
1. Event-Decision Processing is Computationally Intensive
2. CEP requires a Number of Technologies:
  • Distributed Computing, Publish/Subscribe and SOA
  • Hierarchical, Cooperative Inference Processing
  • High Speed, Real Time Processing with State Management
  • Event-Decision Architecture for Complex Situations and Events
  • There is no single “CEP Solution” or “CEP Product” (in the market place then, and today)
3. CEP needs a Common Vocabulary and Functional Architecture based on Mature, Industry-Standard Inference Models
4. Processing and Integration Patterns for CEP need to be Developed and Formalized
Since March of 2006 a number of other challenges*has surfaced.* I will elaborate on this challenges in a future post.

NAME
httppower - communicate with HTTP based power distribution units SYNOPSIS
httppower [--url URL] DESCRIPTION
httppower is a helper program for powerman which enables it to communicate with HTTP based power distribution units. It is run interac- tively by the powerman daemon. OPTIONS
-u, --url URL Set the base URL. INTERACTIVE COMMANDS
The following commands are accepted at the httppower> prompt: auth user:pass Authenticate to the base URL with specified user and password, using ``basic'' HTTP authentication which sends the user and password over the network in plain text. seturl URL Set the base URL. Overrides the command line option. get [URL-suffix] Send an HTTP GET to the base URL with the optional URL-suffix appended. post [URL-suffix] key=val[&key=val]... Send an HTTP POST to the base URL with the optional URL-suffix appended, and key-value pairs as argument. FILES
/usr/sbin/httppower /etc/powerman/powerman.conf ORIGIN
PowerMan was originally developed by Andrew Uselton on LLNL's Linux clusters. This software is open source and distributed under the terms of the GNU GPL. SEE ALSO
