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

i-scream central monitoring system from the CVS repository. |
| 52 |

These builds will have quite a few changes from the downloads |
| 53 |

currently available (a document detailing them will be |
| 54 |

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

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

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

Work has now been finished on a new ihost written in C. This has |
| 65 |
+ |
been in the pipeline for a long time, and we're glad to finally |
| 66 |
+ |
see an efficient native host! Credit goes to our new developer |

We've finally put the finishing touches to the new |
| 76 |
+ |
<a href="http://rrdtool.eu.org">RRDtool</a> based graphing system. |
| 77 |
+ |
It's working well, and has done away with the MySQL database |
| 78 |
+ |
backend which took up far too many resources. This new system |
| 79 |
+ |
generates the graphs in a more realtime nature, allowing more |
| 80 |
+ |
flexible graphs to be generated. This is currently only available |
| 81 |
+ |
through <a href="http://cvs.i-scream.org/cms/source/reports/rrdgraphing/"> |

CVS</a>. |

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

<b>Tuesday 18 Dec 2001</b><br><br> |

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. |

The current system for graphing i-scream data from the i-scream |
| 124 |
< |
system is good, but proving to be unscalable and very resource |
| 125 |
< |
hungry. This is mostly due to the MySQL database backend, |
| 126 |
< |
and the vast quantity of data recorded. The new system |
| 127 |
< |
in development makes use of <a href="http://rrdtool.eu.org/"> |
| 128 |
< |
RRDtool</a> to generate the graphs in realtime. This reduces |
| 129 |
< |
the peak loads of the system, and allows generation of more |
| 78 |
< |
flexible graphs. This work is nearing completetion. |
| 123 |
> |
Work is continuing, in conjunction with the new ihost, to extend |
| 124 |
> |
the range of i-scream's monitoring. Currently we are adding new |
| 125 |
> |
features to more accurately monitoring memory and swap usage, |
| 126 |
> |
along with more disk statistics. We are also planning to improve |
| 127 |
> |
the rather basic service monitors which are currently in place. |
| 128 |
> |
There are also many more subtle changes that need to be made to |
| 129 |
> |
improve the reliability and usefulness of i-scream's monitoring. |
