16     Work has now been finished on a new ihost written in C. This has
17 tdb 1.32 been in the pipeline for a long time, and we're glad to finally
18     see an efficient native host! Credit goes to our new developer
19 tdb 1.31 <a href="/who.shtml">Pete</a>. Until we update the downloads
20     pages you can download the new ihost

27     We've finally put the finishing touches to the new
28     <a href="http://rrdtool.eu.org">RRDtool</a> based graphing system.
29     It's working well, and has done away with the MySQL database
30     backend which took up far too many resources. This new system
31     generates the graphs in a more realtime nature, allowing more
32     flexible graphs to be generated. This is currently only available
33 tdb 1.32 through <a href="http://www.i-scream.org.uk/cgi-bin/cvs/viewcvs.cgi/cms/source/reports/rrdgraphing/">
34 tdb 1.31 CVS</a>.

41 tdb 1.31 to make full downloads, including source, available on this site.

46 tdb 1.30 The alerting section of the i-scream central monitoring system
47     now makes full use of an externally developed IRC bot for it's IRC
48 tdb 1.28 connectivity. To find out more about this IRC bot, please visit

55     Java ACL (Access Control List) code has been added to the util
56     package of the i-scream server. This code will ultimately allow
57     the server to be more secure when exposed to the Internet. More

71     page provides a static example of what the i-scream reports (alerts,
72     historical graphs, and live data) could look like on a production system.

91 tdb 1.31 Work is continuing, in conjunction with the new ihost, to extend
92     the range of i-scream's monitoring. Currently we are adding new
93     features to more accurately monitoring memory and swap usage,
94     along with more disk statistics. We are also planning to improve
95     the rather basic service monitors which are currently in place.
96 tdb 1.32 There are also many more subtle changes that need to be made to
97     improve the reliability and usefulness of i-scream's monitoring.

101 tdb 1.28 <b>Server security</b><br><br>
102     Security was something mostly overlooked in the original stage
103     of this project (due to the academic nature of the work). However,
104     once in production use this has become an issue, and is being
105     addressed. Initially the plan is to lock down the external points
106     of access (TCP & UDP) in the server to specific hosts. In the
107     longer term, encryption of data would be nice, but would take a
108     lot more time and work.

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

126 pjm2 1.14 The i-scream Distributed Central Monitoring System started off as
127 tdb 1.28 a final year project for a group of <a href="http://www.cs.ukc.ac.uk">
128     Computer Science</a> students at the <a href="http://www.ukc.ac.uk">
129     University of Kent at Canterbury</a>, UK. The project was completed at
130     4pm on 29 March 2001. It consisted of five lever-arch folders containing
131     mostly source code and documentation. The CVS repository was tagged to
132     signify this even, however, the project is still being developed by the
133     <a href="acknowledgements.shtml">core development team</a>.
134 tdb 1.6 </p>

136     <p align="justify">
137 pjm2 1.15 <a href="screenshots/"><img border="0" src="screenshots/thumbnail-ihost-main.gif" width="100" height="51" align="right"></a>
138 tdb 1.18 As can be seen in our &quot;<a href="/probdomain.shtml">problem domain</a>&quot; document, the project
139 tdb 1.6 was aimed at the UKC Computer Science department, and as such
140 pjm2 1.22 we believed that a demonstration to the &quot;customer&quot; was important. The
141 pjm2 1.12 feedback from our demonstation was more positive than we had
142 tdb 1.27 anticipated. We believe that the system may now be of interest
143     to anybody who wishes to monitor a number of machines on their
144     network using a central configuration. The i-scream central
145     monitoring system is now being used by the UKC Computer Science
146     department, and their feedback is being used to further improve
147     the product.

152 pjm2 1.14 The name <i>i-scream</i> arose from a meeting whereupon one member
153     of the <a href="acknowledgements.shtml">development team</a> felt a strange urge to draw an ice cream on the discussion board.
154 tdb 1.1 It later became apparent that we had no name for our project (other
155     than 'The Project'). It seemed only natural to name our project after
156     the ice cream that had been oh-so-randomly drawn on the white board.
157     Copyright issues immediately ruled out anything involving Mr Whippy,
158 pjm2 1.14 so we had to settle for <i>i-scream</i>. And thus, we were left with a cunning
159 tdb 1.1 play on words - it still sounded like <i>ice cream</i>, yet also
160 tdb 1.26 served as a functional description of our system - namely, one which
161 tdb 1.1 screams at somebody if something has gone wrong...
