- The "project" stage of i-scream has finished, leaving the
- system in a completed state. Since then the goals have
- changed from completing a project to producing a useful
- and functional product.
- <b><a href="documentation/">Documentation</a></b> is
- available for people wanting to try out the i-scream
- system, and our code is availabel via <a href="cvs.shtml">CVS</a>.
- Our progress during the project can be found in the meeting minutes.
- Work is still continuing to adapt and improve the i-scream central
- monitoring system as a product for use in networked environments.
+ <b>Thursday 7 Feb 2002</b><br><br>
+ The alerting section of the i-scream monitoring system now makes
+ full use of an externally developed IRC bot for it's IRC
+ connectivity. To find out more about this IRC bot, please visit
+ the authors website at <a href="http://www.jibble.org">

- The i-scream Distributed Central Monitoring System Reports
- are no longer visible on the web. You may view some of the
- output in the <b><a href="screenshots/">screen shots</a></b>
- section or you can sample some static example content on the
- <a href="reports/"><b>Reports Demo</b></a> pages.
- You may view the latest information about each machine,
- historical 24-hour reports and alerts for each machine. If
- you would like your i-scream web reports to be linked from this
- site, then please email us at

+ <b>Tuesday 8 Jan 2002</b><br><br>
+ Java ACL (Access Control List) code has been added to the util
+ package of the i-scream server. This code will ultimately allow
+ the server to be more secure when exposed to the Internet. More
+ details can be found <a href="http://www.cs.ukc.ac.uk/people/staff/tdb/#acl">
+ here</a> on the authors website.

- Our current host development allows us to pass machine statistics
- to our distributed filter arrangement, which then processes the
- data and stores it for later use. An example of such use is the
- historical report generator which produces graphs of machine
- usage over periods of time. A real-time
- client is also available (Conient) and alert information can be
- displayed to the public via dynamic web pages.
+ <b>Tuesday 18 Dec 2001</b><br><br>
+ The i-scream ihost package has undergone significant changes to
+ make it more flexible and modular. It now incorporates plugins
+ which can be written in any language, and automatically XML
+ encodes data it is given (as opposed to the hardcoded approach
+ in the old version). It has also been made more robust, and
+ where possible optimised to reduce the load on the host system.

+ <b>Historical/Realtime graphing package</b><br><br>
+ <a href="screenshots/"><img border="0" src="screenshots/thumbnail-reports-raptor-load15.gif" width="100" height="107" align="left"></a>
+ The current system for graphing i-scream data from the i-scream
+ system is good, but proving to be unscalable and very resource
+ hungry. This is mostly due to the MySQL database backend,
+ and the vast quantity of data recorded. The new system
+ in development makes use of <a href="http://rrdtool.eu.org/">
+ RRDtool</a> to generate the graphs in realtime. This reduces
+ the peak loads of the system, and allows generation of more
+ flexible graphs. This work is nearing completetion.

+
+ <p align="justify">
+ <b>Server security</b><br><br>
+ Security was something mostly overlooked in the original stage
+ of this project (due to the academic nature of the work). However,
+ once in production use this has become an issue, and is being
+ addressed. Initially the plan is to lock down the external points
+ of access (TCP & UDP) in the server to specific hosts. In the
+ longer term, encryption of data would be nice, but would take a
+ lot more time and work.

+ <b>Testing and Development</b><br><br>
+ <a href="screenshots/"><img border="0" src="screenshots/thumbnail-winhost-main.gif" width="100" height="62" align="right"></a>
+ The i-scream system is being tested and developed within the
+ Univeristy of Kent Computer Science department by the Systems
+ Group. This has led to many bug fixes and minor feature
+ enhancements, and will hopefully help to aid the long term
+ development of the system.

<a href="screenshots/"><img border="0" src="screenshots/thumbnail-reports-raptor-latest-misc.gif" width="100" height="104" align="left"></a>
The i-scream Distributed Central Monitoring System started off as
- a final year project for a group of <a href="http://www.cs.ukc.ac.uk">Computer Science</a> students at
- the <a href="http://www.ukc.ac.uk">University of Kent at Canterbury</a>, UK.
- The project deadline was 4pm on 29th March 2001. Most of the group
- met very early that morning to compile the project into five
- lever arch folders. The project, consisting of source code, user,
- maintenance and other documents, was handed in at 3pm. The CVS
- repository was tagged to signify the project's completion, however,
- the project is still being developed by the <a href="acknowledgements.shtml">core development team</a>
- as we have found the system to be very useful in practice. We would
- love to hear of ideas for extra features that we may include in the
- next builds.
