F5 Python SDK: How to get virtual server availability?

Due to my limited Python and SDK experience I am finding it difficult to easily obtain the availability state of a virtual server. Given a 'virtual' object, what is the best/easiest way to return the...

This is brutal to work with!

partition  = 'C25'
pool_name = 'temp_test'
pool  = mgmt.tm.ltm.pools.pool.load(name=pool_name, partition=partition)
stats = pool.stats.load()
for item in stats.entries:
        params = stats.entries.get(item).get('nestedStats').get('entries')

stuff = ['activeMemberCnt','curSessions','serverside.curConns','serverside.maxConns','serverside.totConns','status.enabledState','status.availabilityState']

for item in stuff:
        for key in ('value','description'):
                if key in params[item]:
                        print("'{}': {}".format(item,params[item][key]))

OUTPUT:
'activeMemberCnt': 1
'curSessions': 0
'serverside.curConns': 0
'serverside.maxConns': 0
'serverside.totConns': 0
'status.enabledState': enabled
'status.availabilityState': available

    Have you tried the Stats module?

    >>> from f5.utils.responses.handlers import Stats
>>> p = b.tm.ltm.pools.pool.load(name='testpool')
>>> ps = Stats(p.stats.load())
>>> ps.stat.curSessions['value']
0
>>> ps.stat.status_availabilityState['description']
u'offline'
>>> ps.stat.status_enabledState['description']
u'enabled'

    Hi Jason ,

    I tested this for VIP stats and its not working ...

    vis = vip.tm.ltm.virtuals.get_collection()

    vi = vis.virtual.load()

    ps = Stats(vi.stats.load())

    error :

    vi = vis.virtual.load()

    AttributeError: 'list' object has no attribute 'virtual'

    Can you please help me on this .. i know in earlier posts it was mentioned about F5 versions... just checking if that has been fixed ?
