DataModelObject

protected DataModelObject(DataModel model)

Method Detail

containsField

public boolean containsField(java.lang.String fieldName)

Checks whether there is a field with the given name in this data model object.

Parameters:

fieldName - name of the field to check for.

Returns:

true if there is such a field; false otherwise.

createLocalAccelerationJob

public Job createLocalAccelerationJob()

Local acceleration is tsidx acceleration of a data model object that is handled manually by a user. You create a job which generates an index, and then use that index in your pivots on the data model object. The namespace created by the job is 'sid={sid}' where {sid} is the job's sid. You would use it in another job by starting your search query with | tstats ... from sid={sid} | ... The tsidx index created by this job is deleted when the job is garbage collected by Splunk. It is the user's responsibility to manage this job, including cancelling it.

Returns:

a Job writing a tsidx index.

createLocalAccelerationJob

public Job createLocalAccelerationJob(java.lang.String earliestTime)

Local acceleration is tsidx acceleration of a data model object that is handled manually by a user. You create a job which generates an index, and then use that index in your pivots on the data model object. The namespace created by the job is 'sid={sid}' where {sid} is the job's sid. You would use it in another job by starting your search query with | tstats ... from sid={sid} | ... The tsidx index created by this job is deleted when the job is garbage collected by Splunk. It is the user's responsibility to manage this job, including cancelling it.

Parameters:

earliestTime - A time modifier (e.g., "-2w") setting the earliest time to index.

Returns:

a Job writing a tsidx index.

getCalculations

public java.util.Map<java.lang.String,DataModelCalculation> getCalculations()

Return the calculations done by this data model object to produce fields. Each calculation has a unique ID assigned to it by splunkd, which is the key in the returned map. For most purposes you will probably only want the values.

Returns:

a map of calculation IDs to DataModelCalculation objects.

getCalculation

public DataModelCalculation getCalculation(java.lang.String calculationId)

Fetch a calculation by its unique ID.

Parameters:

calculationId - a splunkd assigned unique ID for this calculation.

Returns:

a DataModelCalculation object.

getConstraints

public java.util.Collection<DataModelConstraint> getConstraints()

Returns:

a collection of the constraints limiting events that will appear in this data model object.

getDataModel

public DataModel getDataModel()

Fetch the data model on which this object is defined.

Returns:

A DataModel instance containing this object.

getDisplayName

public java.lang.String getDisplayName()

Returns:

the human readable name of this data model object.

getField

public DataModelField getField(java.lang.String fieldName)

Fetch a single field of a given name from this data model object.

Parameters:

fieldName - Name of the field to fetch.

Returns:

A DataModelField object, or null if there is no field of the given name.

getAutoExtractedFields

public java.util.Collection<DataModelField> getAutoExtractedFields()

Get a collection of objects specifying all the fields that were automatically extracted from events (as opposed to generated by calculations in a data model).

Returns:

a collection of DataModelField objects.

getFields

public java.util.Collection<DataModelField> getFields()

Return all the fields, whether input or created by calculations.

Returns:

a collection of DataModelField objects.

getQuery

public java.lang.String getQuery()

getName

public java.lang.String getName()

Returns:

Splunk's identifier for this data model object.

getLineage

public java.lang.String[] getLineage()

Data model objects can inherit from other data model objects in the same data model (or from a couple of global base objects such as BaseEvent and BaseTransaction). The lineage is a list of data model object names tracing this inheritance, starting with the most remote ancestor and ending with this object.

Returns:

An array of names, starting with this object's name, followed by the names up the hierarchy.

getParentName

public java.lang.String getParentName()

Returns the name of the parent of this object.

Returns:

a String giving the name.

getParent

public DataModelObject getParent()

Returns:

the data model object this one inherits from if it is a user defined data model object in the same data model; otherwise returns null (for example if the data model object inherits from BaseEvent or BaseTransaction).

createPivotSpecification

public PivotSpecification createPivotSpecification()

Create a PivotSpecification on this data model object.

Returns:

a PivotSpecification instance.

runQuery

public Job runQuery()

Start a job that fetches all the events of this data model object.

Returns:

a Job object.

runQuery

public Job runQuery(JobArgs args)

Start a job that fetches all the events of this data model object.

Parameters:

args - arguments specifying behavior of the job.

Returns:

a Job object.

runQuery

public Job runQuery(java.lang.String querySuffix)

Start a job that applies querySuffix to all the events in this data model object.

Parameters:

querySuffix - a search query, starting with a '|' that will be appended to the command to fetch the contents of this data model object (e.g., "| head 3").

Returns:

a Job object.

runQuery

public Job runQuery(java.lang.String querySuffix,
                    JobArgs args)

Start a job that applies querySuffix to all the events in this data model object.

Parameters:

querySuffix - a search query, starting with a '|' that will be appended to the command to fetch the contents of this data model object (e.g., "| head 3").

args - arguments to control the job.

Returns:

a Job object.
