Re: [Openstack] Kwapi architecture

[François Rossigneux]

Hello Krishnaprasad, I recently updated and published the documentation of Kwapi: https://kwapi.readthedocs.org/ And I created a project home page here: https://launchpad.net/kwapi As Simon said, Kwapi aims at monitoring physical machines, with wattmeters. It is not aware of the VMs running on physical hosts, neither of their resource usage (% CPU). Kwapi doesn't depend of OpenStack components, except the API plugin which is able to check Keystone tokens. However, your idea is really interesting and I will be happy if this feature could be implemented in Kwapi. So I suggest to create a new plugin (or adapt the API plugin). Every x seconds, for each known host, it will get the resource usage of each running VM. The probes names will have to be configured properly, so that the probes names = the Nova hostnames. Each measurement will be split into multiple measurements, one for each VM. Please feel free to create a blueprint here: https://blueprints.launchpad.net/kwapi/+addspec Regards, François Le 26/07/2013 16:34, Simon Pasquier a écrit : Hello Krishnaprasad, I forwarded your message to Francois who's maintaining the kwapi project. I presume you've already seen this page which presents the kwapi architecture: http://www.xlcloud.org/bin/view/XLcloudProjectManagement/EEA Francois will confirm or infirm but as I understand, there has been no short-term plan for kwapi to monitor the energy consumption of the VM.

On the web I found that, Ceilometer has Kwapi that measures the power on hosts (compute nodes) and for VMs, the implementation is under progress.   Can I get a feedback from the community regarding the following questions? a)      Where can I find the Kwapi architecture for the energy prediction in VMs? b)      Where can I find information regarding components specified in the Kwapi architecture? c)       Can I get to know the overall progress in the implementation for the energy prediction in VMs?   Currently, we are outlining an architecture for measuring the energy in VMs and in this regard, the answers to above questions will be helpful.   Thanks Krishnaprasad _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp -- Simon Pasquier Software Engineer Bull, Architect of an Open World Phone: + 33 4 76 29 71 49 http://www.bull.com _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp -- François Rossigneux Ingénieur Inria Projet XLcloud http://perso.ens-lyon.fr/francois.rossigneux
