For example do not use <type>.image but image:<type>, where type is your variable name.

User-defined sample metadata (nova only)
=========================================
Users are allowed to add additional metadata to samples of nova meter.
These additional metadata are stored in 'resource_metadata.user_metadata.*' of the sample
To do so, users should add nova user metadata prefixed with 'metering.':
::
$ nova boot --meta metering.custom_metadata=a_value my_vm
Note: The name of the metadata shouldn't exceed 256 characters otherwise it will be cut off.
Also, if it has '.', this will be replaced by a '_' in ceilometer.
