+ Work has now been finished on a new ihost written in C. This has
+ been in the pipeline for a long time, and we're glad to finally
+ see an efficient native host! Credit goes to our new developer
+ <a href="/who.shtml">Pete</a>. Until we update the downloads
+ pages you can download the new ihost
+ <a href="http://ukc.i-screma.org.uk/snapshots/ihost-1.0rc1.tar.gz">

- Several central components are now functioning to initial
- design parameters and data can now be passed through the
- system successfully. Many planning and design decisions
- are still being made, along with various specification
- documents. Detailed information can usually be found in
- the meeting minutes. Code is viewable via CVS to UKC
- users only.

+ We've finally put the finishing touches to the new
+ <a href="http://rrdtool.eu.org">RRDtool</a> based graphing system.
+ It's working well, and has done away with the MySQL database
+ backend which took up far too many resources. This new system
+ generates the graphs in a more realtime nature, allowing more
+ flexible graphs to be generated. This is currently only available
+ through <a href="http://www.i-scream.org.uk/cgi-bin/cvs/viewcvs.cgi/cms/source/reports/rrdgraphing/">
+ CVS</a>.

- 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 (viewable in a web browser). Realtime
- clients are also currently being developed - one Java Swing GUI
- version and also a command line version that can run in a terminal
- window.

+ The alerting section of the i-scream central monitoring system

+ 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">

+ <b>Extending monitoring facilites</b><br><br>
+ <a href="screenshots/"><img border="0" src="screenshots/thumbnail-reports-raptor-load15.gif" width="100" height="107" align="left"></a>
+ Work is continuing, in conjunction with the new ihost, to extend
+ the range of i-scream's monitoring. Currently we are adding new
+ features to more accurately monitoring memory and swap usage,
+ along with more disk statistics. We are also planning to improve
+ the rather basic service monitors which are currently in place.
+ There are also many more subtle changes that need to be made to
+ improve the reliability and usefulness of i-scream's monitoring.

+ <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.

+ <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.

- <center><h3>Naming History</h3></center>

<p align="justify">
- The name <b>i-scream</b> arose from a meeting whereupon one member
- of our group randomly chose to draw an ice cream on the white board.
+ <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 was completed at
+ 4pm on 29 March 2001. It consisted of five lever-arch folders containing
+ mostly source code and documentation. The CVS repository was tagged to
+ signify this even, however, the project is still being developed by the
+ <a href="acknowledgements.shtml">core development team</a>.
+ </p>
+
+ <p align="justify">
+ <a href="screenshots/"><img border="0" src="screenshots/thumbnail-ihost-main.gif" width="100" height="51" align="right"></a>
+ As can be seen in our "<a href="/probdomain.shtml">problem domain</a>" document, the project
+ was aimed at the UKC Computer Science department, and as such
+ we believed that a demonstration to the "customer" was important. The
+ feedback from our demonstation was more positive than we had
+ anticipated. We believe that the system may now be of interest
+ to anybody who wishes to monitor a number of machines on their
+ network using a central configuration. The i-scream central
+ monitoring system is now being used by the UKC Computer Science
+ department, and their feedback is being used to further improve
+ the product.

+ The name <i>i-scream</i> arose from a meeting whereupon one member
+ of the <a href="acknowledgements.shtml">development team</a> felt a strange urge to draw an ice cream on the discussion board.
It later became apparent that we had no name for our project (other
than 'The Project'). It seemed only natural to name our project after
the ice cream that had been oh-so-randomly drawn on the white board.
Copyright issues immediately ruled out anything involving Mr Whippy,

play on words - it still sounded like <i>ice cream</i>, yet also
