+ Over the coming week we will be making snapshot builds of the
+ i-scream central monitoring system from the CVS repository.
+ These builds will have quite a few changes from the downloads
+ currently available (a document detailing them will be
+ released later on), so please give them a whirl. We would be
+ grateful if you contacted
+ us with any questions or bugs.
+ Work has now been finished on a new ihost written in C. This has
+ been in the pipeline for a long time, and we're glad to finally
+ see an efficient native host! Credit goes to our new developer
+ Pete. Until we update the downloads
+ pages you can download the new ihost

+ We've finally put the finishing touches to the new
+ RRDtool based graphing system.
+ It's working well, and has done away with the MySQL database
+ backend which took up far too many resources. This new system
+ generates the graphs in a more realtime nature, allowing more
+ flexible graphs to be generated. This is currently only available
+ through
+ CVS.

Java ACL (Access Control List) code has been added to the util
package of the i-scream server. This code will ultimately allow
the server to be more secure when exposed to the Internet. More

- 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.

Current Work
- Historical/Realtime graphing package
+ Extending monitoring facilites
- The current system for graphing i-scream data from the i-scream
- system is good, but proving to be unscalable and very resource
- hungry. This is mostly due to the MySQL database backend,
- and the vast quantity of data recorded. The new system
- in development makes use of
- RRDtool 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.
+ Work is continuing, in conjunction with the new ihost, to extend
+ the range of i-scream's monitoring. Currently we are adding new
+ features to more accurately monitoring memory and swap usage,
+ along with more disk statistics. We are also planning to improve
+ the rather basic service monitors which are currently in place.
+ There are also many more subtle changes that need to be made to
+ improve the reliability and usefulness of i-scream's monitoring.
