Java Virtual Machines (JVM)
The fields in the JVM data model describe generic Java server platforms.
Note: A dataset is a component of a data model. In versions of the Splunk platform prior to version 6.5.0, these were referred to as data model objects.
Tags used with JVM event datasets
The following tags act as constraints to identify your events as being relevant to this data model. For more information, see How to use these reference tables.
Dataset name | Tag name |
---|---|
JVM | jvm |
|
threading |
|
runtime |
|
os |
|

Fields for JVM event datasets
The following table lists the extracted and calculated fields for the event datasets in the model. Note that it does not include any inherited fields. For more information, see How to use these reference tables.
The key for using the column titled "Notes" or "Abbreviated list of example values" is as follows:
- Recommended: Add-on developers make their best effort attempts to map these event fields. If these fields are not populated, then the event is not very useful.
- Required: Add-on developers must map these event fields when using the pytest-splunk-addon to test for CIM compatibility. See pytest-splunk-addon documentation.
- Prescribed values: Permitted values that can populate the fields, which Splunk is using for a particular purpose. Other valid values exist, but Splunk is not relying on them.
- Other values: Other example values that you might see.
