16            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

27            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 i-scream ihost package has undergone significant changes to  
         make it more flexible and modular. It now incorporates plugins  
         which can be written in any language, and automatically XML  
         encodes data it is given (as opposed to the hardcoded approach  
         in the old version). It has also been made more robust, and  
         where possible optimised to reduce the load on the host system.

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