16 The alerting section of the i-scream monitoring system now makes
17 full use of an externally developed IRC bot for it's IRC
18 connectivity. To find out more about this IRC bot, please visit
19 the author's website at <a href="http://www.jibble.org">

25 Java ACL (Access Control List) code has been added to the util
26 package of the i-scream server. This code will ultimately allow
27 the server to be more secure when exposed to the Internet. More
28 details can be found <a href="http://www.cs.ukc.ac.uk/people/staff/tdb/#acl">
29 here</a> on the author's website.

34 The i-scream ihost package has undergone significant changes to
35 make it more flexible and modular. It now incorporates plugins
36 which can be written in any language, and automatically XML
37 encodes data it is given (as opposed to the hardcoded approach
38 in the old version). It has also been made more robust, and
39 where possible optimised to reduce the load on the host system.

47 Details of the i-scream central monitoring system can be found
48 on the <b><a href="features.shtml">features and overview</a></b> page.
49 A variety of <b><a href="screenshots">screen shots</a></b> from the
50 system show some of the key features in use. The <b><a href="reports">reports demo</a></b>
51 page provides a static example of what the i-scream reports (alerts,
52 historical graphs, and live data) could look like on a production system.

57 The latest source code is available in the <b><a href="cvs.shtml">CVS</a></b>
58 repository, with binary downloads on the downloads page. The
59 <b><a href="documentation">documentation</a></b> page has details of
60 installation, use and maintenance for the end user and developer.

71 The current system for graphing i-scream data from the i-scream
72 system is good, but proving to be unscalable and very resource
73 hungry. This is mostly due to the MySQL database backend,
74 and the vast quantity of data recorded. The new system
75 in development makes use of <a href="http://rrdtool.eu.org/">
76 RRDtool</a> to generate the graphs in realtime. This reduces
77 the peak loads of the system, and allows generation of more
78 flexible graphs. This work is nearing completetion.

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

95 The i-scream system is being tested and developed within the
96 Univeristy of Kent Computer Science department by the Systems
97 Group. This has led to many bug fixes and minor feature
98 enhancements, and will hopefully help to aid the long term
99 development of the system.

107 The i-scream Distributed Central Monitoring System started off as
108 a final year project for a group of <a href="http://www.cs.ukc.ac.uk">
109 Computer Science</a> students at the <a href="http://www.ukc.ac.uk">
110 University of Kent at Canterbury</a>, UK. The project was completed at
111 4pm on 29 March 2001. It consisted of five lever-arch folders containing
112 mostly source code and documentation. The CVS repository was tagged to
113 signify this even, however, the project is still being developed by the
114 <a href="acknowledgements.shtml">core development team</a>.

118 <a href="screenshots/"><img border="0" src="screenshots/thumbnail-ihost-main.gif" width="100" height="51" align="right"></a>
119 As can be seen in our &quot;<a href="/probdomain.shtml">problem domain</a>&quot; document, the project
120 was aimed at the UKC Computer Science department, and as such
121 we believed that a demonstration to the &quot;customer&quot; was important. The
122 feedback from our demonstation was more positive than we had
123 anticipated. We believe that the system may now be of interest
124 to anybody who wishes to monitor a number of machines on their
125 network using a central configuration. The i-scream central
126 monitoring system is now being used by the UKC Computer Science
127 department, and their feedback is being used to further improve
128 the product.

133 The name <i>i-scream</i> arose from a meeting whereupon one member
134 of the <a href="acknowledgements.shtml">development team</a> felt a strange urge to draw an ice cream on the discussion board.
135 It later became apparent that we had no name for our project (other
136 than 'The Project'). It seemed only natural to name our project after
137 the ice cream that had been oh-so-randomly drawn on the white board.
138 Copyright issues immediately ruled out anything involving Mr Whippy,
139 so we had to settle for <i>i-scream</i>. And thus, we were left with a cunning
140 play on words - it still sounded like <i>ice cream</i>, yet also
141 served as a functional description of our system - namely, one which
142 screams at somebody if something has gone wrong...
