How can I get VM instance running time in openstack via python API? -


i need small billing report usage of vms inside openstack after stopped, far find way flavor information (vcpu, disk, memory) instance name.

and want know vm's startup time calculate now.

are there ways fetch openstack python api ?

it nice if can paste code well.

(i got answer china-openstack community, , shared here)

in novaclient usage module, instance (active or terminated) can fetched list api, detail information fetched via get api, not clear information exposed via python document.

fortunately openstack api : os-simple-tenant-usage tells data structure, uptime want.

 "tenant_usage": {     "server_usages": [         {             ... (skipped)             "uptime": 3600,             "vcpus": 1         }     ],

openstack dashboard (at least folsom version) use api well.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
