Over the coming week we will be making snapshot builds of the |

i-scream central monitoring system from the CVS repository. |

These builds will have quite a few changes from the downloads |

currently available (a document detailing them will be |
| 20 |

released later on), so please give them a whirl. We would be |

grateful if you <a href="mailto:dev@i-scream.org.uk">contacted</a> |
| 22 |

us with any questions or bugs.<br><br> |

Most i-scream components are now functioning to initial |
| 30 |
< |
design parameters and data can now be passed through the |
| 31 |
< |
system and displayed successfully. Documentation is still |
| 32 |
< |
being generated, to allow for future development of the |
| 33 |
< |
i-scream project. Detailed information can usually be |
| 34 |
< |
found in the meeting minutes. Code is viewable via CVS |
| 35 |
< |
to UKC users only. |

see an efficient native host! Credit goes to our new developer |

We've finally put the finishing touches to the new |
| 42 |
> |
<a href="http://rrdtool.eu.org">RRDtool</a> based graphing system. |
| 43 |
> |
It's working well, and has done away with the MySQL database |
| 44 |
> |
backend which took up far too many resources. This new system |
| 45 |
> |
generates the graphs in a more realtime nature, allowing more |
| 46 |
> |
flexible graphs to be generated. This is currently only available |
| 47 |

through <a href="http://www.i-scream.org.uk/cgi-bin/cvs/viewcvs.cgi/cms/source/reports/rrdgraphing/"> |

Our current host development allows us to pass machine statistics |
| 53 |
< |
to our distributed filter arrangement, which then processes the |
| 54 |
< |
data and stores it for later use. An example of such use is the |
| 55 |
< |
historical report generator which produces graphs of machine |
| 37 |
< |
usage over periods of time (viewable in a web browser). Realtime |
| 38 |
< |
clients are also currently being developed - one Java Swing GUI |
| 39 |
< |
version and also a command line version that can run in a terminal |
| 40 |
< |
window. Alerting mechanisms are being put in place to complete the |
| 41 |
< |
i-scream system. |

Work is continuing, in conjunction with the new ihost, to extend |
| 106 |
+ |
the range of i-scream's monitoring. Currently we are adding new |
| 107 |
+ |
features to more accurately monitoring memory and swap usage, |
| 108 |
+ |
along with more disk statistics. We are also planning to improve |
| 109 |
+ |
the rather basic service monitors which are currently in place. |
| 110 |
+ |
There are also many more subtle changes that need to be made to |
| 111 |
+ |
improve the reliability and usefulness of i-scream's monitoring. |

<b>Server security</b><br><br> |
| 116 |
+ |
Security was something mostly overlooked in the original stage |
| 117 |
+ |
of this project (due to the academic nature of the work). However, |
| 118 |
+ |
once in production use this has become an issue, and is being |
| 119 |
+ |
addressed. Initially the plan is to lock down the external points |
| 120 |
+ |
of access (TCP & UDP) in the server to specific hosts. In the |
| 121 |
+ |
longer term, encryption of data would be nice, but would take a |
| 122 |
+ |
lot more time and work. |

The i-scream system is being tested and developed within the |
| 129 |
+ |
Univeristy of Kent Computer Science department by the Systems |
| 130 |
+ |
Group. This has led to many bug fixes and minor feature |
| 131 |
+ |
enhancements, and will hopefully help to aid the long term |
| 132 |
+ |
development of the system. |

The project deadline is 4pm on 29 March. As such, we plan to |
| 140 |

complete the coding process by (at the latest) the end of the |
| 141 |
< |
project week (26/2 - 2/3). This allows time for documentation |

to be tidied up and completed, and printing of the project. |

The i-scream Distributed Central Monitoring System started off as |
| 141 |

a final year project for a group of <a href="http://www.cs.ukc.ac.uk"> |
| 142 |
> |
Computer Science</a> students at the <a href="http://www.ukc.ac.uk"> |
| 143 |

University of Kent at Canterbury</a>, UK. The project was completed at |
| 144 |
> |
4pm on 29 March 2001. It consisted of five lever-arch folders containing |
| 145 |
> |
mostly source code and documentation. The CVS repository was tagged to |
| 146 |

signify this even, however, the project is still being developed by the |

As can be seen in our "<a href="/probdomain.shtml">problem domain</a>" document, the project |

was aimed at the UKC Computer Science department, and as such |
| 154 |

we believe a demonstration to the "customer" is important. We |

plan to do this over the next two weeks, and the feedback given |

we believed that a demonstration to the "customer" was important. The |

feedback from our demonstation was more positive than we had |

anticipated. We believe that the system may now be of interest |
| 157 |

to anybody who wishes to monitor a number of machines on their |
| 158 |

network using a central configuration. The i-scream central |

It later became apparent that we had no name for our project (other |
