Work has now been finished on a new ihost written in C. This has |
| 17 |
+ |
been in the pipeline for a long time, and we're glad to see an |
| 18 |
+ |
efficient host at last! Credit goes to our new developer |
| 19 |

<a href="/who.shtml">Pete</a>. Until we update the downloads |
| 20 |
+ |
pages you can download the new ihost |
| 21 |

We've finally put the finishing touches to the new |
| 28 |
+ |
<a href="http://rrdtool.eu.org">RRDtool</a> based graphing system. |
| 29 |
+ |
It's working well, and has done away with the MySQL database |
| 30 |
+ |
backend which took up far too many resources. This new system |
| 31 |
+ |
generates the graphs in a more realtime nature, allowing more |
| 32 |
+ |
flexible graphs to be generated. This is currently only available |
| 33 |
+ |
through <a href="http://www.i-scream.org.uk/cgi-bin/cvs/viewcvs.cgi/cms/source/reports/rrdgraphing/" |
| 34 |
+ |
CVS</a>. |

The alerting section of the i-scream central monitoring system |
| 47 |
|
now makes full use of an externally developed IRC bot for it's IRC |

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 |
| 92 |
< |
system is good, but proving to be unscalable and very resource |
| 93 |
< |
hungry. This is mostly due to the MySQL database backend, |
| 94 |
< |
and the vast quantity of data recorded. The new system |
| 95 |
< |
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. |
| 91 |
> |
Work is continuing, in conjunction with the new ihost, to extend |
| 92 |
> |
the range of i-scream's monitoring. Currently we are adding new |
| 93 |
> |
features to more accurately monitoring memory and swap usage, |
| 94 |
> |
along with more disk statistics. We are also planning to improve |
| 95 |
> |
the rather basic service monitors which are currently in place. |
