Most i-scream components are now functioning to initial |
16 |

design parameters and data can now be passed through the |
17 |

system and displayed successfully. Documentation is still |
18 |

being generated, to allow for future development of the |

i-scream project. Detailed information can usually be |
20 |

found in the meeting minutes. Code is viewable via CVS |

Our current host development allows us to pass machine statistics |
56 |
< |
to our distributed filter arrangement, which then processes the |
57 |
< |
data and stores it for later use. An example of such use is the |
58 |
< |
historical report generator which produces graphs of machine |
59 |
< |
usage over periods of time (viewable in a web browser). Realtime |
60 |
< |
clients are also currently being developed - one Java Swing GUI |
61 |
< |
version and also a command line version that can run in a terminal |
62 |
< |
window. Alerting mechanisms are being put in place to complete the |
41 |
< |
i-scream system. |

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

<a href="http://rrdtool.eu.org">RRDtool</a> based graphing system. |
69 |

It's working well, and has done away with the MySQL database |
70 |

backend which took up far too many resources. This new system |
71 |
+ |
generates the graphs in a more realtime nature, allowing more |
72 |

flexible graphs to be generated. This is currently only available |

Work is continuing, in conjunction with the new ihost, to extend |
116 |
+ |
the range of i-scream's monitoring. Currently we are adding new |
117 |
+ |
features to more accurately monitoring memory and swap usage, |
118 |
+ |
along with more disk statistics. We are also planning to improve |
119 |
+ |
the rather basic service monitors which are currently in place. |
120 |
+ |
There are also many more subtle changes that need to be made to |
121 |
+ |
improve the reliability and usefulness of i-scream's monitoring. |

<b>Server security</b><br><br> |
126 |
+ |
Security was something mostly overlooked in the original stage |
127 |
+ |
of this project (due to the academic nature of the work). However, |
128 |
+ |
once in production use this has become an issue, and is being |
129 |
+ |
addressed. Initially the plan is to lock down the external points |
130 |
+ |
of access (TCP & UDP) in the server to specific hosts. In the |
131 |
+ |
longer term, encryption of data would be nice, but would take a |
132 |
+ |
lot more time and work. |

The i-scream system is being tested and developed within the |
139 |
+ |
Univeristy of Kent Computer Science department by the Systems |
140 |
+ |
Group. This has led to many bug fixes and minor feature |
141 |
+ |
enhancements, and will hopefully help to aid the long term |
142 |
+ |
development of the system. |

complete the coding process by (at the latest) the end of the |

The i-scream Distributed Central Monitoring System started off as |

a final year project for a group of <a href="http://www.cs.kent.ac.uk"> |
152 |

Computer Science</a> students at the <a href="http://www.kent.ac.uk"> |
153 |

University of Kent at Canterbury</a>, UK. The project was completed at |
154 |

4pm on 29 March 2001. It consisted of five lever-arch folders containing |
155 |

mostly source code and documentation. The CVS repository was tagged to |

to anybody who wishes to monitor a number of machines on their |
