Thanks a lot Micheal. Works like a charm :)
How does one know that you need to access first field in
statistic.get_values().get_value()[0].datum.
Are these documented any place ?
you can see this in api [1] there is a collection of values
represented by <value> place-hoder, you can find discussion
on statistics api modelling at the old rhevm-api [2] mailing list.
<values type="...">
<value>
<datum>...</datum>
</value>
</values>
[1] GET http://server:[port]/api/hosts/xxx/statistics
[2] https://lists.fedorahosted.org/pipermail/rhevm-api/

Deepthi
