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
threading
|____ Runtime

|____ OS

|____ Compilation

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.

Dataset name Field name Data type Description Possible values
JVM jvm_description string A description field provided in some data sources.
JVM tag string This automatically generated field is used to access tags from within datamodels. Add-on builders do not need to populate it.
Threading cm_enabled boolean Indicates whether thread contention monitoring is enabled. true, false, 1, 0
Threading cm_supported boolean Indicates whether the JVM supports thread contention monitoring. true, false, 1, 0
Threading cpu_time_enabled boolean Indicates whether thread CPU time measurement is enabled. true, false, 1, 0
Threading cpu_time_supported boolean Indicates whether the Java virtual machine supports CPU time measurement for the current thread. true, false, 1, 0
Threading current_cpu_time number CPU-space time taken by the JVM, in seconds.
Threading current_user_time number User-space time taken by the JVM, in seconds.
Threading daemon_thread_count number The JVM's current daemon count.
Threading omu_supported boolean Indicates whether the JVM supports monitoring of object monitor usage. true, false, 1, 0
Threading peak_thread_count number The JVM's peak thread count.
Threading synch_supported boolean Indicates whether the JVM supports monitoring of ownable synchronizer usage. true, false, 1, 0
Threading thread_count number The JVM's current thread count.
Threading threads_started number The total number of threads started in the JVM.
Runtime process_name string Process name of the JVM process.
Runtime start_time timestamp Start time of the JVM process.
Runtime uptime number Uptime of the JVM process, in seconds.
Runtime vendor_product string The JVM product or service. This field can be automatically populated by the the vendor and product fields in your raw data.
Runtime version string Version of the JVM.
OS committed_memory number Amount of memory committed to the JVM, in bytes.
OS cpu_time number Amount of CPU time taken by the JVM, in seconds.

OS max_file_descriptors number Maximum file descriptors available to the JVM.
OS open_file_descriptors number Number of file descriptors opened by the JVM.
OS os string OS that the JVM is running on.
OS os_architecture string OS architecture that the JVM is running on.
OS os_version string OS version that the JVM is running on.
OS physical_memory number Physical memory available to the OS that the JVM is running on, in bytes.
OS swap_space number Swap memory space available to the OS that the JVM is running on, in bytes.
OS system_load number System load of the OS that the JVM is running on.
OS total_processors number Total processor cores available to the OS that the JVM is running on.
Compilation compilation_time number Time taken by JIT compilation, in seconds.
Classloading current_loaded number The current count of classes loaded in the JVM.
Classloading total_loaded number The total count of classes loaded in the JVM.
Classloading total_unloaded number The total count of classes unloaded from the JVM.
Memory heap_committed number Committed amount of heap memory used by the JVM, in bytes.
Memory heap_initial number Initial amount of heap memory used by the JVM, in bytes.
Memory heap_max number Maximum amount of heap memory used by the JVM, in bytes.
Memory heap_used number Heap memory used by the JVM, in bytes.
Memory non_heap_committed number Committed amount of non-heap memory used by the JVM, in bytes.
Memory non_heap_initial number Initial amount of non-heap memory used by the JVM, in bytes.
Memory non_heap_max number Maximum amount of non-heap memory used by the JVM, in bytes.
Memory non_heap_used number Non-heap memory used by the JVM, in bytes.
Memory objects_pending number Number of objects pending in the JVM, in bytes.
