Hi Michael ,
Thanks for ur continuous help. I have one more query here
I want to fetch the host elements like ..
Type
address
status
No. of CPUs
cpu-type
cpu - name-topology-cores-sockets
memory
summary
version
Is is the correct way of doing to get these details?
hosts=api.hosts.list()
for host in hosts:
type=api.hosts.get(host.id http://host.id).type
address=api.hosts.get(host.id http://host.id).address
no, please use getter methods instead as they're encapsulating attributes that
may be
called differently in python,
for instance 'type' attribute in python renamed to 'type_' cause 'type' is
preserved name.
you can see all available get_X() methods by running code bellow:
# print [token for token in type(host.superclass).__dict__.keys() if
token.startswith('get_')]
I got some exception :
address=api.hosts.get(host.id http://host.id).get_address()
AttributeError: 'NoneType' object has no attribute 'get_address'
this can only happen if your host lookup has failed.
Please suggest me the correct way of doing it if have referred

print statistic[i].name
print statistic[i].description
print statistic[i].unit
print statistic[i].values.value[0].datum
i=i+1;
summary=api.get_summary()
print summary
How I can print the summary , its only return the Object??
this is summary object structure:
summary
vms
total/total
active/active
/vms
hosts
total/total
active/active
/hosts
users
total/total
active/active
/users
storage_domains
total/total
active/active
/storage_domains
/summary
you can access properties directly, like this:
summary.hosts.active
Thanks,
Romil

statistics=params.Host(host.name http://host.name
http://host.name http://host.name).get_statistic()
1. first you need to fetch the host to see it's statistics (by
doing params.Host(...) you creating
host parameters holder which is needed for adding new host to
the system)
2. get_x() getters used to access object attributes, while
collections are exposed as properties, do
1. myhost = api.hosts.get(name=xxx)
2. myhost.statistics.list()
3. loop over returned collection of statistics to find what you're
looking for
- note, statistic objects are complex types, you can look for data
at:
statistics[i].unit // the unit of the holder data
statistics[i].values.value[0].datum // actual data
print statistics
summary=params.Host(host.name http://host.name
http://host.name http://host.name).get_summary()
summary() is an api method, do:
1. api = API(url='', username='', password='')
2. api.get_summary()
print summary
Output is : none
Thanks
