We've finally put the finishing touches to the new |

<a href="http://rrdtool.eu.org">RRDtool</a> based graphing system. |
| 29 |

It's working well, and has done away with the MySQL database |

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 |

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 |
| 44 |
< |
client is also available (Conient) and alert information can be |
| 45 |
< |
displayed to the public via dynamic web pages. |

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. |

<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. |

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. |

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, |
| 71 |
< |
the project is still being developed by the <a href="acknowledgments.shtml">core development team</a> |
| 72 |
< |
as we have found the system to be very useful in practice. We would |
| 73 |
< |
love to hear of ideas for extra features that we may include in the |
| 74 |
< |
next builds. |

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 |
|
It later became apparent that we had no name for our project (other |
| 157 |
|
Copyright issues immediately ruled out anything involving Mr Whippy, |
| 158 |
|
so we had to settle for <i>i-scream</i>. And thus, we were left with a cunning |
| 159 |
|
play on words - it still sounded like <i>ice cream</i>, yet also |

served as a functional decription of our system - namely, one which |
