+ 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.

+ The downloads will be available on our snapshot server :-

+ 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. +

- 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.
