The alerting section of the i-scream monitoring system now makes |
| 17 |
|
|
full use of an externally developed IRC bot for it's IRC |
| 18 |
|

connectivity. To find out more about this IRC bot, please visit |

Java ACL (Access Control List) code has been added to the util |
| 26 |
|
|
package of the i-scream server. This code will ultimately allow |
| 27 |
|
|
the server to be more secure when exposed to the Internet. More |

<b>Tuesday 18 Dec 2001</b><br><br> |
| 34 |
|
|
The i-scream ihost package has undergone significant changes to |
| 35 |
|
|
make it more flexible and modular. It now incorporates plugins |
| 36 |
|
|
which can be written in any language, and automatically XML |
| 37 |
|
|
encodes data it is given (as opposed to the hardcoded approach |
| 38 |
|
|
in the old version). It has also been made more robust, and |
| 39 |
|
|
where possible optimised to reduce the load on the host system. |

<b>Historical/Realtime graphing package</b><br><br> |

The current system for graphing i-scream data from the i-scream |
| 72 |
|
|
system is good, but proving to be unscalable and very resource |
| 73 |
|
|
hungry. This is mostly due to the MySQL database backend, |
| 74 |
|
|
and the vast quantity of data recorded. The new system |
| 75 |
|
|
in development makes use of <a href="http://rrdtool.eu.org/"> |
| 76 |
|
|
RRDtool</a> to generate the graphs in realtime. This reduces |
| 77 |
|
|
the peak loads of the system, and allows generation of more |
| 78 |
|
|
flexible graphs. This work is nearing completetion. |

<b>Server security</b><br><br> |
| 83 |
|
|
Security was something mostly overlooked in the original stage |
| 84 |
|
|
of this project (due to the academic nature of the work). However, |
| 85 |
|
|
once in production use this has become an issue, and is being |
| 86 |
|
|
addressed. Initially the plan is to lock down the external points |
| 87 |
|
|
of access (TCP & UDP) in the server to specific hosts. In the |
| 88 |
|
|
longer term, encryption of data would be nice, but would take a |
| 89 |
|
|
lot more time and work. |

The i-scream system is being tested and developed within the |
| 96 |
|
|
Univeristy of Kent Computer Science department by the Systems |
| 97 |
|
|
Group. This has led to many bug fixes and minor feature |
| 98 |
|
|
enhancements, and will hopefully help to aid the long term |
| 99 |
|
|
development of the system. |

The i-scream Distributed Central Monitoring System started off as |
| 108 |
tdb |
1.28 |
a final year project for a group of <a href="http://www.cs.ukc.ac.uk"> |
| 109 |
|
|
Computer Science</a> students at the <a href="http://www.ukc.ac.uk"> |
| 110 |
|
|
University of Kent at Canterbury</a>, UK. The project was completed at |
| 111 |
|
|
4pm on 29 March 2001. It consisted of five lever-arch folders containing |
| 112 |
|
|
mostly source code and documentation. The CVS repository was tagged to |
| 113 |
|
|
signify this even, however, the project is still being developed by the |
| 114 |
|
|
<a href="acknowledgements.shtml">core development team</a>. |

As can be seen in our "<a href="/probdomain.shtml">problem domain</a>" document, the project |
| 120 |
tdb |
1.6 |
was aimed at the UKC Computer Science department, and as such |
| 121 |
pjm2 |
1.22 |
we believed that a demonstration to the "customer" was important. The |
| 122 |
pjm2 |
1.12 |
feedback from our demonstation was more positive than we had |
| 123 |
tdb |
1.27 |
anticipated. We believe that the system may now be of interest |
| 124 |
|
|
to anybody who wishes to monitor a number of machines on their |
| 125 |
|
|
network using a central configuration. The i-scream central |
| 126 |
|
|
monitoring system is now being used by the UKC Computer Science |
| 127 |
|
|
department, and their feedback is being used to further improve |
| 128 |
|
|
the product. |

The name <i>i-scream</i> arose from a meeting whereupon one member |
| 134 |
|
|
of the <a href="acknowledgements.shtml">development team</a> felt a strange urge to draw an ice cream on the discussion board. |
| 135 |
tdb |
1.1 |
It later became apparent that we had no name for our project (other |
| 136 |
|
|
than 'The Project'). It seemed only natural to name our project after |
| 137 |
|
|
the ice cream that had been oh-so-randomly drawn on the white board. |
| 138 |
|
|
Copyright issues immediately ruled out anything involving Mr Whippy, |
| 139 |
pjm2 |
1.14 |
so we had to settle for <i>i-scream</i>. And thus, we were left with a cunning |
| 140 |
tdb |
1.1 |
play on words - it still sounded like <i>ice cream</i>, yet also |
| 141 |
tdb |
1.26 |
served as a functional description of our system - namely, one which |
| 142 |
tdb |
1.1 |
screams at somebody if something has gone wrong... |
