Over the coming week we will be making snapshot builds of the |
| 48 |
i-scream central monitoring system from the CVS repository. |
| 49 |
These builds will have quite a few changes from the downloads |
| 50 |
currently available (a document detailing them will be |
| 51 |
released later on), so please give them a whirl. We would be |
| 52 |
grateful if you <a href="mailto:dev@i-scream.org">contacted</a> |
| 53 |
us with any questions or bugs.<br><br> |
| 54 |

Work has now been finished on a new ihost written in C. This has |
| 62 |
been in the pipeline for a long time, and we're glad to finally |
| 63 |
see an efficient native host! Credit goes to our new developer |
| 64 |
<a href="/who.shtml">Pete</a>. Until we update the downloads |
| 65 |
pages you can download the new ihost |

We've finally put the finishing touches to the new |
| 73 |
<a href="http://rrdtool.eu.org">RRDtool</a> based graphing system. |
| 74 |
It's working well, and has done away with the MySQL database |
| 75 |
backend which took up far too many resources. This new system |
| 76 |
generates the graphs in a more realtime nature, allowing more |
| 77 |
flexible graphs to be generated. This is currently only available |
| 78 |
through <a href="http://cvs.i-scream.org/cms/source/reports/rrdgraphing/"> |
| 79 |
CVS</a>. |

Java ACL (Access Control List) code has been added to the util |

package of the i-scream server. This code will ultimately allow |
| 86 |
the server to be more secure when exposed to the Internet. More |

Work is continuing, in conjunction with the new ihost, to extend |
| 121 |
the range of i-scream's monitoring. Currently we are adding new |
| 122 |
features to more accurately monitoring memory and swap usage, |
| 123 |
along with more disk statistics. We are also planning to improve |
| 124 |
the rather basic service monitors which are currently in place. |
| 125 |
There are also many more subtle changes that need to be made to |
| 126 |
improve the reliability and usefulness of i-scream's monitoring. |

<b>Server security</b><br><br> |
| 131 |
Security was something mostly overlooked in the original stage |
| 132 |
of this project (due to the academic nature of the work). However, |
| 133 |
once in production use this has become an issue, and is being |
| 134 |
addressed. Initially the plan is to lock down the external points |
| 135 |
of access (TCP & UDP) in the server to specific hosts. In the |
| 136 |
longer term, encryption of data would be nice, but would take a |
| 137 |
lot more time and work. |

The i-scream system is being tested and developed within the |
| 144 |
Univeristy of Kent Computer Science department by the Systems |
| 145 |
Group. This has led to many bug fixes and minor feature |
| 146 |
enhancements, and will hopefully help to aid the long term |
| 147 |
development of the system. |

The i-scream Distributed Central Monitoring System started off as |
| 156 |
a final year project for a group of <a href="http://www.cs.kent.ac.uk"> |
| 157 |
Computer Science</a> students at the <a href="http://www.kent.ac.uk"> |
| 158 |
University of Kent at Canterbury</a>, UK. The project was completed at |
| 159 |
4pm on 29 March 2001. It consisted of five lever-arch folders containing |
| 160 |
mostly source code and documentation. The CVS repository was tagged to |
| 161 |
signify this even, however, the project is still being developed by the |
| 162 |
<a href="acknowledgements.shtml">core development team</a>. |

| 167 |
As can be seen in our "<a href="/probdomain.shtml">problem domain</a>" document, the project |
| 168 |
was aimed at the UKC Computer Science department, and as such |
| 169 |
we believed that a demonstration to the "customer" was important. The |
| 170 |
feedback from our demonstation was more positive than we had |
| 171 |
anticipated. We believe that the system may now be of interest |
| 172 |
to anybody who wishes to monitor a number of machines on their |
| 173 |
network using a central configuration. The i-scream central |
| 174 |
monitoring system is now being used by the UKC Computer Science |
| 175 |
department, and their feedback is being used to further improve |
| 176 |
the product. |

The name <i>i-scream</i> arose from a meeting whereupon one member |
| 182 |
of the <a href="acknowledgements.shtml">development team</a> felt a strange urge to draw an ice cream on the discussion board. |
| 183 |
It later became apparent that we had no name for our project (other |
| 184 |
than 'The Project'). It seemed only natural to name our project after |
| 185 |
the ice cream that had been oh-so-randomly drawn on the white board. |
| 186 |
Copyright issues immediately ruled out anything involving Mr Whippy, |
| 187 |
so we had to settle for <i>i-scream</i>. And thus, we were left with a cunning |
| 188 |
play on words - it still sounded like <i>ice cream</i>, yet also |
| 189 |
served as a functional description of our system - namely, one which |
| 190 |
screams at somebody if something has gone wrong... |
