WildFly 10.0 Model Reference

The management interface for the thread system of the Java virtual machine.

Runtime only resource This resource is runtime only and doesn't have any persistent configuration.

Attributes (15)

all-thread-ids All live thread IDs. If a security manager is installed and the caller does not have ManagementPermission("monitor"), then a "read-attribute" operation reading this attribute will fail, and the value for this attribute in the result for the "read-resource" operation will be "undefined".

Attribute	Value

Nillable	false
Expressions Allowed	false
Storage	runtime
Access Type	read-only

current-thread-cpu-time The total CPU time for the current thread in nanoseconds, or -1 if "thread-cpu-time-enabled" is "false". A Java virtual machine implementation may not support CPU time measurement. If "thread-cpu-time-supported", is "false" trying to read this attribute via the "read-attribute" operation will result in failure, and the value of this attribute in the result of a "read-resource" operation will be "undefined".

current-thread-user-time The CPU time that the current thread has executed in user mode in nanoseconds, or -1 if "thread-cpu-time-enabled" is "false". A Java virtual machine implementation may not support CPU time measurement. If "thread-cpu-time-supported", is "false" trying to read this attribute via the "read-attribute" operation will result in failure, and the value of this attribute in the result of a "read-resource" operation will be "undefined".

get-thread-infos Returns the thread info for each thread whose ID is in the input list.

Request Parameter	Type	Required	Expressions Allowed	Default value	Description
ids	LIST	true	false		A list of thread ids.
max-depth	INT	true	false	0	The maximum number of entries in the stack trace to be dumped. Integer.MAX_VALUE could be used to request the entire stack to be dumped.
locked-monitors	BOOLEAN	true	false	false	A list of detyped representations java.lang.management.MonitorInfo objects, each of which represents an object monitor currently locked by the thread.
locked-synchronizers	BOOLEAN	true	false	false	A list of detyped representations java.lang.management.LockInfo objects, each of which represents an ownable synchronizer currently locked by the thread.

Reply properties

A list of detyped representations of java.lang.management.ThreadInfo objects, each containing information about a thread whose ID is in the corresponding element of the input list of IDs. An element will be "undefined" if the thread of the given ID is not alive or it does not exist.

read-resource Reads a model resource's attribute values along with either basic or complete information about any child resources

Request Parameter	Type	Required	Expressions Allowed	Default value	Description
recursive	BOOLEAN	false	false		Whether to include complete information about child resources, recursively. If absent, false is the default
recursive-depth	INT	false	false		The depth to which information about child resources should be included.
proxies	BOOLEAN	false	false	false	Whether to include remote resources in a recursive query (i.e. host level resources in a query of the domain root; running server resources in a query of a host). If absent, false is the default.
include-runtime	BOOLEAN	false	false	false	Whether to include runtime attributes (i.e. those whose value does not come from the persistent configuration) in the response. If absent, false is the default.
include-defaults	BOOLEAN	false	false	true	Boolean to enable/disable default reading. In case it is set to false only attribute set by user are returned ignoring undefined.
attributes-only	BOOLEAN	false	false	false	Whether or not to only read the attributes on the specified resource. Cannot be used in conjunction with 'recursive' or 'recursive-depth'.
include-aliases	BOOLEAN	false	false	false	If 'true' and recursive, include children which are aliases.
