python sdk : how to get disks from storage domain
Hello, I'm writing a python script to draw a graph of the disks and virtual machines in relation to their "position" in the data center. I am using pygraphviz to draw the graph, I found the vm and their disks, data centers and their storage domains, but I can not connect the disks to the storage domains. Here's the code I'm using: #! /usr/bin/python import pygraphviz as PG from ovirtsdk.api import API from ovirtsdk.xml import params #per Graphviz: A = PG.AGraph(directed=True, strict=False) A.graph_attr.update(size="800") ######## VERSION = params.Version(major='3', minor='0') URL = 'https://xxx/api' USERNAME = 'xxx' PASSWORD = 'yyyy' api = API ( url=URL, username=USERNAME, password=PASSWORD, insecure=True) for vm in api.vms.list(): for disco in vm.get_disks().list(): A.add_edge(vm.name,disco.name) for dc in api.datacenters.list(): A.add_edge("ovirt-engine", dc.get_name()) for dc_storage in dc.storagedomains.list(): A.add_edge(dc.get_name(), dc_storage.name) api.disconnect() A.write('ovirt_graph.dot') A.layout(prog='dot') A.draw('ovirt_graph.png') # draw png
Hi Giorgio, You can simply do: dc_storage.disks.list() hope that helps Thanks, Raz Tamir Red Hat Israel On Thu, Nov 5, 2015 at 7:41 PM, Giorgio Bart <giorgiobart300@gmail.com> wrote:
