C.2 Interpreting the Units of Metrics Fact Values
The Orchestrate Agent converts most of the Ganglia metrics values to PlateSpin Orchestrate standard units. This allows fact values to be compared in constraints without the need to perform conversions explicitly. In cases where units are not known or cannot be converted, a separate fact with a .units suffix is included. For example:
<fact name="resource.metrics.bytes_in" value="bytes/sec" type="String" />
The following table lists the resource.metrics facts and the units of measure used for each fact value:
