Dasein Cloud
by Thijs Metsch 23 Jun '13

23 Jun '13

Hi, Just to inform you that there is a cool project going on called Dasein-Cloud. http://dasein-cloud.sourceforge.net/ On the website it reads: Dasein Cloud is an Open Source Java API made available by enStratus Networks LLC under the terms of the Apache License 2.0. This API specifies cloud-independent interfaces for enabling an application to access resources across multiple clouds. If you are interested have a look - and it might be great to implement OCCI in their someday!

Status on OCCI - OpenStack Folsom

Dear All, I've successfully installed OpenStack for CentOS 6.3 (Folsom) and now I was trying to add the OCCI support since we want to implement some APIs for testing the interoperability with other cloud solutions. I was following the instructions reported in this link: https://github.com/tmetsch/occi-os and suggested by Florian Feldhaus. Unfortunately the distribution i was looking for (occi-os-folsom) seems not be available in the repo. $ pip-python install occi-os-folsom Downloading/unpacking occi-os-folsom Could not find any downloads that satisfy the requirement occi-os-folsom *No distributions at all found for occi-os-folsom* Storing complete log in /root/.pip/pip.log From repo the only available distribution is the previous one .. $ pip-python install openstackocci Downloading/unpacking openstackocci *Downloading openstackocci-essex-1.1.tar.gz* Running setup.py egg_info for package openstackocci Requirement already satisfied (use --upgrade to upgrade): distribute in /usr/lib/python2.6/site-packages (from openstackocci) Installing collected packages: openstackocci Running setup.py install for openstackocci Successfully installed openstackocci Cleaning up...

Re: [occi-wg] Dedicated call on OCCI and Monitoring

I re-read the "collector centric" revision and I found that the absence of a resource (i.e. an accountable entity) in a configuration that was considered as typical was not a good idea. However, the simplification of the simplest case was clearly desirable. So I slightly modified the model: the CollectorSet mixin has been moved from the Collector to the Sensor. So that now the sensor describes how the metrics are published. I modified the label of the CollectorSet to PublisherSet for consistency. In the new model the simplest case is now "one collector + one sensor". There are less constraints that must be implemented (which means lower computatonal cost), compared to both recent models (the one presented during the confcall and the collector centric one labelled with "Focus on single stage"). The new version of the doc has been checked out on the repo (monitoring branch), and can be downloaded using the direct link: http://redmine.ogf.org/projects/occi-wg/repository/revisions/monitoring/raw… The typo on the presentation (that is now slightly obsolete) has been fixed. I will revise it soon to make adherent to the doc.

Notes on monitoring call
by Augusto Ciuffoletti 05 Apr '13

05 Apr '13

Hi all, here following is a short memo I did for myself about last call. I can add further points, if needed: please let me know. Subtyping vs Collection: in the document the collection is used to denote a subtyping relationship between mixins: this is inconsistent with sect. 4.4.8 in the core document (collection is for instances). Use subtyping/related as defined in 4.4.4 in the core document. Add a statement about this in the doc. The simplest case has an interest since it models existing cases (like Cloudwatch). Maybe I will add an appendix with the figures illustrated in the paper, but avoiding volatile references. I did not reply to a question about how to browse a mixin sub-type. There is one bug: AggregatorSet instead of "Computetool" in the "POST". In fact the example is incomplete in that respect, and an example should be added to the document. Although conceptually clear, the exact format for a query is not explicit in the documents I know. Basically this is a GET with a filter: my guess is the following. > GET /-/monitoring/aggregatorset HTTP/1.1 > ... > term = "threshold" Not very powerful, but probably good for the task. Right? Bye Augusto -- Augusto Ciuffoletti Dipartimento di Informatica Università di Pisa 56100 - Pisa (Italy)
