Example with additional setting for aggregation:

Info collector XML elements: metricAbstract - what metrics can be used in information collector XML element. See 'Sub Types' section of man page

How metrics and validators mentioned above are implemented you can see in section: Implementations of collectors
What is the difference between metrics, validators, collectors you can see in section: Custom collectors
