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

summary() is an api method, do:

1. api = API(url='', username='', password='')
2. api.get_summary()
