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
