public interface WLDFHarvesterManagerRuntimeMBean
Provides statistical information relative to a particular configured Harvester instance, and a means to retreive an on-demand snapshot of configured attribute values.

retrieveSnapshot()
Retrieves a snapshot of values for attributes configured in this Harvester instance at the moment the request is made; these values are returned to the caller and not persisted in the WLDF archive. |

Map<ObjectName,AttributeList> retrieveSnapshot() throws JMException
Retrieves a snapshot of values for attributes configured in this Harvester instance at the moment the request is made; these values are returned to the caller and not persisted in the WLDF archive. The Harvester instance does not need to be actively polling for this call to be made.
The returned Map contains a list of instances collected from and the set of values harvested from each instance. The map key is the ObjectName of MBean instance that the values were retrieved from, and the value for each key is an AttributeList containing the attributes and values retrieved from that instance.
Each returned snapshot will contain an implicit entry accessed by the reserved key "serverTimestamp"; its AttributeList payload will consist of a single attribute of the name "serverTimestamp", where the value for that "attribute" will be the timestamp in milliseconds, relative to the server, that the snapshot request was made.
NOTE that the attribute names in the returned AttributeList instances may not map to an actual attribute on the target MBean. For example, this would be the case where the attribute of a WLDFHarvestedTypeBean is actually an attribute expression, or in the case above where the snapshot timestamp is returned as an "attribute" of the WLDFHarvesterManagerRuntimeMBean instance it was requested from.
JMException
