This is the original specification we were given when we took |

on the project, and it seems an ideal basis for the problem |

The Computer Science department has a number of different machines |
| 46 |
tdb |
1.1 |
running a variety of different operating systems. One of the tasks |
| 47 |
|
|
of the systems administrators is to make sure that the machines |
| 48 |
|
|
don't run out of resources. This involves watching processor loads, |
| 49 |
|
|
available disk space, swap space, etc. |
| 50 |
|
|
</p> |
| 51 |
|
|
|
| 52 |
|
|
<p align="justify"> |
| 53 |
|
|
It isn't practicle to monitor a large number of machines by logging |
| 54 |
|
|
on and running commands such as 'uptime' on the unix machines, or |
| 55 |
|
|
by using performance monitor for NT servers. Thus this project is |
| 56 |
|
|
to write monitoring software for each platform supported which |
| 57 |
|
|
reports resource usage back to one centralized location. System |
| 58 |
|
|
Administrators would then be able to monitor all machines from this |
| 59 |
|
|
centralised location. |

|
|
</p> |
| 61 |
|
|
|
| 62 |
|
|
<p align="justify"> |
| 63 |
|
|
Once this basic functionality is implemented it could usefully be |
| 64 |
|
|
expanded to include logging of resource usage to identify longterm |
| 65 |
|
|
trends/problems, alerter services which can directly contact |
| 66 |
|
|
sysadmins (or even the general public) to bring attention to problem |
| 67 |
|
|
areas. Ideally it should be possible to run multiple instances of |
| 68 |
|
|
the reporting tool (with all instances being updated in realtime) |
| 69 |
|
|
and to to be able to run the reporting tool as both as stand alone |
| 70 |
|
|
application and embeded in a web page. |

This project will require you to write code for the unix and Win32 |
| 75 |
|
|
APIs using C and knowledge of how the underlying operating systems |
| 76 |
|
|
manage resources. It will also require some network/distributed |
| 77 |
|
|
systems code and a GUI front end for the reporting tool. It is |
| 78 |
|
|
important for students undertaking this project to understand the |
| 79 |
|
|
importance of writing efficient and small code as the end product |
| 80 |
|
|
will really be most useful when machines start run out of processing |
| 81 |
|
|
power/memory/disk. |

John Cinnamond (email jc) whose idea this is, will provide technical |

|
|
support for the project. |
