27 <        All i-scream components now function to initial
28 <        design parameters and our system is regarded to be complete.
29 <        <b><a href="documentation/">Documentation</a></b> is available to assist third party programmers
30 <        in producing Hosts for use with the i-scream server.
31 <        Our progress during the project can be found in the meeting minutes.

40 <        The i-scream Distributed Central Monitoring System <a href="http://raptor.ukc.ac.uk/~pjm2/reports">Reports</a>
41 <        are now visible on the web.  If you are <b>not</b> a local user, then you may

31 <        You may view the latest information about each machine, historical 24-hour
32 <        reports and alerts for each machine.  Our own i-scream server is running constantly,
33 <        along with several hosts to enable plenty of data harvesting.  If you would

46 <        Our current host development allows us to pass machine statistics
47 <        to our distributed filter arrangement, which then processes the
48 <        data and stores it for later use.  An example of such use is the
49 <        historical report generator which produces graphs of machine
50 <        usage over periods of time.  A real-time
45 <        client is also available (Conient) and alert information can be
46 <        displayed to the public via dynamic web pages.

91 +        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 +        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 +        <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          The i-scream Distributed Central Monitoring System started off as
127 <        a final year project for a group of <a href="http://www.cs.ukc.ac.uk">Computer Science</a> students at
128 <        the <a href="http://www.ukc.ac.uk">University of Kent at Canterbury</a>, UK.
129 <        The project deadline was 4pm on 29th March 2001.  Most of the group
130 <        met very early that morning to compile the project into five
131 <        lever arch folders.  The project, consisting of source code, user,
132 <        maintenance and other documents, was handed in at 3pm.  The CVS
133 <        repository was tagged to signify the project's completion, however,
72 <        the project is still being developed by the <a href="acknowledgements.shtml">core development team</a>
73 <        as we have found the system to be very useful in practice.  We would
74 <        love to hear of ideas for extra features that we may include in the
75 <        next builds.
