16 +        Over the coming week we will be making snapshot builds of the
17 +        i-scream central monitoring system from the CVS repository.
18 +        These builds will have quite a few changes from the downloads
19 +        currently available (a document detailing them will be
20 +        released later on), so please give them a whirl. We would be
21 +        grateful if you <a href="mailto:dev@i-scream.org">contacted</a>
22 +        us with any questions or bugs.<br><br>

30 +        Work has now been finished on a new ihost written in C. This has
31 +        been in the pipeline for a long time, and we're glad to finally
32 +        see an efficient native host! Credit goes to our new developer
33 +        <a href="/who.shtml">Pete</a>. Until we update the downloads

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

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

34        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.

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