         This is the original specification we were given when we took | 
 
 
 
 
 
 | 38 | 
         on the project, and it seems an ideal basis for the problem |

         domain. |

         The Computer Science department has a number of different machines | 
 
 
 
 
 
 | 46 | 
         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 |

        <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. | 
 
 
 
 
 
 | 60 | 
        </p> |

 | 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. |
