How can I monitor resource of VMs on Openstack by Splunk?

[Takajian]

I would like to get resource information of Virtual Machine on Openstack? Has anybody ever tried this? I am not sure how can I get such information from Openstack. It may be done by API or command execution as scripted input or syslog although I am not sure. Any advice is appreciated.

No answer here, but we're also looking for an app of some sort to monitor our Openstack installation.
