13 QWG Monitoring Templates Discussion

- Integration of templates related to monitoring tools : who support them ? who use them ? For Nagios we have to different set of templates based on 2 slightly different approaches : how we evaluate them and if possible merge them ? how information defined once in quattor can be used to configure both client and server for a range of monitoring services. For example, being able to configure a logical group of machines once and then have that translated into the appropriate lemon (or nagios or ganglia) configuration.

Speaker: Michel Jouvin (LAL / IN2P3)

19 NCM Component Updates

A review of changes to core components over the last 6 months. Morgan Stanley: we've made a number of enhancements to some core components. Many of these patches have now been submitted back into the trunk. This talk runs through the status of the changes to illustrate what new features are available with the cron, download and rootpw components, and the ccm, spma and ncm-ncd subsystems, and to get feedback on a couple of proposals: subclassing components and component status tracking (for testing if a configuration is up-to-date).

Speaker: Nick Williams (Morgan Stanley)

Wrap-up

26 European FP7 Project for Quattor

Although the community is doing a good job in maintaining the quattor toolkit, the community lacks resources to expand, streamline, and document it. This fall there will be an FP7 Infrastructures call related to software for the European Grid Infrastructure. This scope of this call will include more than just the gLite middleware and will likely have an explict reference to deployment and management of grid services. Support gained from such a project would allow us to dedicate effort to improve significantly the toolkit. This discussion is to determine if there is interest in submitting such a proposal and if so, what the program of work should be.

Speaker: Cal Loomis (CNRS/LAL)

27 Improving Quattor's Accessibility

Although a powerful systems management toolkit, quattor suffers from the impression that it is difficult to understand and to use, especially for people new to systems management. The aim of the discussion is to determine how the community can make the quattor toolkit easier to use and thus more accessible to system administrators.

Speaker: Cal Loomis (CNRS/LAL)

Slides 20090311-quattor-accessibility-v1.pdf 20090311-quattor-accessibility-v1.ppt

28 Quattor Software Process

The quattor community already has in place some tools to help with software maintenance and development as well as an automatic build system. The standard tools (bug tracking, code versioning, etc.) will probably converge to a coherent set with the move to the SourceForge repository. However, additional techniques such as static analysis and consistent use of unit tests could help improve the overall quality of the quattor toolkit. This short presentation and following discussion aims to converge on additional tools and/or techniques that the community would like to use during the development and release process.

Speaker: Cal Loomis (CNRS/LAL)
