3.3.2.6.1. JBoss AS 7 and EAP 6 - Memory Pool Resource Service
Overview
Table 3.295. Overview
| Description: | The management interface for a memory pool. A memory pool represents the memory resource managed by the Java virtual machine and is managed by one or more memory managers. |
| Singleton: | no |
| Plugin: | JBossAS7 |
Child Resource Types
none
Connection Properties

Metrics
Table 3.297. Metrics
| Name | Type | Description | Internal Name |
|---|---|---|---|
| Collection Usage - Init | measurement | The amount of memory in bytes that the Java virtual machine initially requests from the operating system for memory management. | collection-usage:init |
| Collection Usage - Used | measurement | The amount of used memory in bytes. | collection-usage:used |
| Collection Usage - Committed | measurement | The amount of memory in bytes that is committed for the Java virtual machine to use. | collection-usage:committed |
| Collection Usage - Max | measurement | The maximum amount of memory in bytes that can be used for memory management. | collection-usage:max |
| Collection Usage Threshold Count | measurement | The number of times that the Java virtual machine has detected that the memory usage has reached or exceeded the collection usage threshold. A memory pool may not support a collection usage threshold. If 'collection-usage-threshold-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'. | collection-usage-threshold-count |
| Collection Usage Threshold Exceeded | measurement | Whether the memory usage of this memory pool after the most recent collection on which the Java virtual machine has expended effort has reached or exceeded its collection usage threshold. A memory pool may not support a collection usage threshold. If 'collection-usage-threshold-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'. | collection-usage-threshold-exceeded |
| Collection Usage Threshold Supported | trait | Whether this memory pool supports a collection usage threshold. | collection-usage-threshold-supported |
| Name | trait | The name representing this memory pool. | name |
| Peak Usage - Init | measurement | The amount of memory in bytes that the Java virtual machine initially requests from the operating system for memory management. | peak-usage:init |
| Peak Usage - Used | measurement | The amount of used memory in bytes. | peak-usage:used |
| Peak Usage - Committed | measurement | The amount of memory in bytes that is committed for the Java virtual machine to use. | peak-usage:committed |
| Peak Usage - Max | measurement | The maximum amount of memory in bytes that can be used for memory management. | peak-usage:max |
| Type | trait | The type of this memory pool. | type |
| Usage - Init | measurement | The amount of memory in bytes that the Java virtual machine initially requests from the operating system for memory management. | usage:init |
| Usage - Used | measurement | The amount of used memory in bytes. | usage:used |
| Usage - Committed | measurement | The amount of memory in bytes that is committed for the Java virtual machine to use. | usage:committed |
| Usage - Max | measurement | The maximum amount of memory in bytes that can be used for memory management. | usage:max |
| Usage Threshold Count | measurement | The number of times that the memory usage has crossed the usage threshold. A memory pool may not support a usage threshold. If 'usage-threshold-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'. | usage-threshold-count |
| Usage Threshold Exceeded | measurement | Whether the memory usage of this memory pool reaches or exceeds its usage threshold value. A memory pool may not support a usage threshold. If 'usage-threshold-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'. | usage-threshold-exceeded |
| Usage Threshold Supported | trait | Whether this memory pool supports usage threshold. | usage-threshold-supported |
| Valid | trait | Whether this memory pool is valid in the Java virtual machine. A memory pool becomes invalid once the Java virtual machine removes it from the memory system. | valid |

You must use the internal name to reference Traits in Dynamic Group Definition expressions.
Configuration Properties

| Name | Description | Required | Internal Name |
|---|---|---|---|
| Collection Usage Threshold | The collection usage threshold value of this memory pool in bytes. A memory pool may not support a collection usage threshold. If 'collection-usage-threshold-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'. | no | collection-usage-threshold |
| Memory Manager Names | The names of the memory managers that manage this memory pool. | yes | memory-manager-names |
| Usage Threshold | The usage threshold value of this memory pool in bytes. A memory pool may not support a usage threshold. If 'usage-threshold-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'. | no | usage-threshold |
