Hi Paul, thanks for your email. I'm curious, was MonAMI done within the context of some EU grid project?
In principle we have nothing against new packages providing new functionality. And making a component look like an OSCAR package is not too difficult. Unfortunately we are somewhat behind in documenting the new package format, the best you can get is at https://svn.oscar.openclustergroup.org/trac/oscar/wiki/BuildOpkg Foreign packages can be added with the help of OPD, so if you want to package MonAMI and build the RPMs for the supported distributions, this would be great. We can help you with packaging and adding it's reference to some OPD repository. You'll need some web space to provide the package to other OSCAR users. And if it turns out that the package is interesting and used by many people, we can also think about integrating it fully into OSCAR. Can you please give some more details on MonAMI? I understand it runs resource measurement programs in /etc/monami.d/. Does it do that in fixed or variable periods of time? Variable per metric? How about the announcement of the results to the monitoring program (eg. ganglia): is it done at fixed periods of time? What happens if a metric measurement doesn't return or takes too long? Does MonAMI by any means aggregate check results? Thanks, best regards, Erich On Tuesday 31 October 2006 19:01, Paul Millar wrote: > [NB.
