Provides information about harvestable and harvested attributes, types, and instances. Harvestable means potentially available for harvesting; harvested means explicitly designated for harvesting. These terms apply to types, instances, and the attributes within those types. In addition, the interface provides access to sampling and snapshot statistics. All statistics are base on data collected during the current server session.
If you use the getMBeanInfo operation in MBeanTypeServiceMBean, supply the following value as this MBean's fully qualified interface name:
weblogic.management.runtime.WLDFHarvesterRuntimeMBean
Since 9.0.0.0
No factory methods. Instances of this MBean are created automatically.
You can access this MBean from the following MBean attributes:

This section describes the following attributes:
The average amount of time, in nanoseconds, spent in sampling cycles.
| Privileges | Read only |
| Type | long |
The number of collected data samples in the current snapshot.
| Privileges | Read only |
| Type | long |
Whether or not the sampling time for the most recent data sample differed significantly enough from the average to be considered a statistical outlier.
| Privileges | Read only |
| Type | boolean |
The elapsed time, in nanoseconds, of a snapshot.
| Privileges | Read only |
| Type | long |
The start time, in nanoseconds, of a snapshot.
| Privileges | Read only |
| Type | long |
The set of all known types, regardless of whether the types are currently configured for harvesting. The set includes the WebLogic Server MBeans, which are always present, plus any other types that can be discovered. MBeans that are not WebLogic Server MBeans will require instances to exist in order to discover the type.
| Privileges | Read only |
| Type | class java.lang.String[] |
The maximum sampling time, in nanoseconds.
| Privileges | Read only |
| Type | long |
The minimum sampling time, in nanoseconds.
| Privileges | Read only |
| Type | long |
The name of this configuration. WebLogic Server uses an MBean to implement and persist the configuration.
| Privileges | Read only |
| Type | java.lang.String |
The multiplicative factor used to determine a statistical outlier. If the actual sampling time exceeds this the session average multiplied by the outlier detection factor, then the sampling time is considered to be a statistical outlier.
| Privileges | Read only |
| Type | float |
Return the immediate parent for this MBean
| Privileges | Read/Write |
| Type |
The current global sample period, in nanoseconds.
| Privileges | Read only |
| Type | long |
The number of configured data samples that have been collected so far in this server session.
| Privileges | Read only |
| Type | long |
The total number of sampling cycles taken thus far.
| Privileges | Read only |
| Type | long |
The total amount of time, in nanoseconds, spent in sampling cycles.
| Privileges | Read only |
| Type | long |
The number of times withing this server session that the sampling time differed significantly enough from the average to be considered a statistical outlier. The Harvester removes these values form the ongoing averages.
| Privileges | Read only |
| Type | long |
Returns the type of the MBean.

| Type | java.lang.String |
This section describes the following operations:
The set of attributes that are currently being harvested for the specified type. The specified type must be explicitly configured for harvesting.
The returned set of attributes usually matches the corresponding set of attributes configured for harvesting; but if an error occurs when harvesting an attribute, that attribute will be omitted from the returned set.
| Operation Name | "getCurrentlyHarvestedAttributes" |
| Parameters | Object [] {
type }
where:
|
| Signature | String [] {
"java.lang.String" } |
| Returns |
class |
weblogic.diagnostics.harvester.HarvesterException$MissingConfigurationType
weblogic.diagnostics.harvester.HarvesterException$HarvestingNotEnabled
weblogic.diagnostics.harvester.HarvesterException$AmbiguousTypeName
The set of instances that are currently being harvested for the specified type. The type must be configured for harvesting.
The returned set of instances usually matches the corresponding set of instances configured for harvesting; but if an error occurs when harvesting an instance, that instance will be omitted from the returned set.
| Operation Name | "getCurrentlyHarvestedInstances" |
| Parameters | Object [] {
type }
where:
|
| Signature | String [] {
"java.lang.String" } |
| Returns |
class |
weblogic.diagnostics.harvester.HarvesterException$MissingConfigurationType
weblogic.diagnostics.harvester.HarvesterException$HarvestingNotEnabled
weblogic.diagnostics.harvester.HarvesterException$AmbiguousTypeName
The set of attributes that are eligible for harvesting for the specified type. The specified type does not need to be currently configured for harvesting. For MBeans other than WebLogic Server MBeans, returns null until at least one instance has been created.
The returned array represents a list of pairs. The first element in each pair is the attribute name and the second element is the class name of the attribute's type.
| Operation Name | "getHarvestableAttributes" |
| Parameters | Object [] {
type }
where:
|
| Signature | String [] {
"java.lang.String" } |
| Returns |
class |
weblogic.diagnostics.harvester.HarvesterException$HarvestableTypesNotFoundException
weblogic.diagnostics.harvester.HarvesterException$AmbiguousTypeName
weblogic.diagnostics.harvester.HarvesterException$TypeNotHarvestable
The type associated with a particular harvestable instance.
| Operation Name | "getHarvestableType" |
| Parameters | Object [] {
instanceName }
where:
|
| Signature | String [] {
"java.lang.String" } |
| Returns | String
|
weblogic.diagnostics.harvester.HarvesterException$HarvestableInstancesNotFoundException
weblogic.diagnostics.harvester.HarvesterException$AmbiguousInstanceName
The set of instances that are eligible for harvesting for the specified type at the time of the call. The type does not need to be currently configured for harvesting.
The caller should be aware that instances come and go. This method returns only those instances that exist at the time of the call.
For MBeans that are not WebLogic Server MBeans, returns null until at least one instance has been created.
| Operation Name | "getKnownHarvestableInstances" |
| Parameters | Object [] {

| Signature | String [] {
"java.lang.String" } |
| Returns |
class |
weblogic.diagnostics.harvester.HarvesterException$HarvestableTypesNotFoundException
