Project News

- Most i-scream components are now functioning to initial - design parameters and data can now be passed through the - system and displayed successfully. Documentation is still - being generated, to allow for future development of the - i-scream project. Detailed information can usually be - found in the meeting minutes. Code is viewable via CVS - to UKC users only. + Wednesday 11 February 2004

+ libstatgrab 0.8.2 has been released.

- The i-scream Distributed Central Monitoring System Reports - are now visible on the web. You may view the latest information - about each machine, historical 24-hour reports and alerts for - each machine. Please remember that this is work in progress - still, so the only data currently viewable is our own data that - has been harvested by our own testing. Also note that historical - reports are only available for periods during which our server - was running. + Tuesday 15 July 2003

+ We have moved the i-scream support and bug tracking to a new + facility on the i-scream server. For further details please + see this page.

+ +

+ Sunday 8 June 2003

+ The i-scream website, email, and cvs facilities are now all + run from a FreeBSD server.
+ + Powered By FreeBSD + +

+ +

+ Tuesday 4 February 2003

+ 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 :-
+ + http://snapshots.i-scream.org/. +

- Our current host development allows us to pass machine statistics - to our distributed filter arrangement, which then processes the - data and stores it for later use. An example of such use is the - historical report generator which produces graphs of machine - usage over periods of time (viewable in a web browser). Realtime - clients are also currently being developed - one Java Swing GUI - version and also a command line version that can run in a terminal - window. Alerting mechanisms are being put in place to complete the - i-scream system. + Saturday 1 June 2002

+ 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 + + here.

+ +

+ Tuesday 21 May 2002

+ 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. +

+ +

+ Tuesday 8 Jan 2002

+ 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 + details can be found + here on the author's website. +

About i-scream

+

- Builds of the i-scream Distributed Central Monitoring System - are now available for download from this - website. These are still very much in development and should - only be used by people who have been in communication with the - development team. + + Details of the i-scream central monitoring system can be found + on the features and overview page. + A variety of screen shots from the + system show some of the key features in use. The reports demo + page provides a static example of what the i-scream reports (alerts, + historical graphs, and live data) could look like on a production system.

+ +

+ + The latest source code is available in the CVS + repository, with binary downloads on the downloads page. The + documentation page has details of + installation, use and maintenance for the end user and developer. + We value feedback and comments from you, so please drop us an e-mail + to dev@i-scream.org. +

Current Work

+ +

+ Extending monitoring facilites

+ + 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. +

+

+ Server security

+ Security was something mostly overlooked in the original stage + of this project (due to the academic nature of the work). However, + once in production use this has become an issue, and is being + addressed. Initially the plan is to lock down the external points + of access (TCP & UDP) in the server to specific hosts. In the + longer term, encryption of data would be nice, but would take a + lot more time and work. +

+ +

+ Testing and Development

+ + The i-scream system is being tested and developed within the + Univeristy of Kent Computer Science department by the Systems + Group. This has led to many bug fixes and minor feature + enhancements, and will hopefully help to aid the long term + development of the system. +

Project History

The project was completed at + 4pm on 29 March 2001. It consisted of five lever-arch folders containing + mostly source code and documentation. The CVS repository was tagged to + signify this even, however, the project is still being developed by the + core development team.

Naming History

It later became apparent that we had no name for our project (other than 'The Project'). It seemed only natural to name our project after the ice cream that had been oh-so-randomly drawn on the white board. Copyright issues immediately ruled out anything involving Mr Whippy, - so we had to settle for i-scream. And thus, we were left with a cunning + so we had to settle for i-scream.
