Intelligent Management: health controller custom properties
You can use health controller custom properties to change the behavior of your health controller. For example, you can change the amount of time that passes before a runtime task that is generated for a health issue expires.
_CEE_DMPTARG
The _CEE_DMPTARG custom property specifies the location that is used for thread dumps on z/OS® systems.
Value | Description |
---|---|
Scope | Application server |
Valid value | A string that indicates the location where you want to save the thread dumps |
com.ibm.ws.xd.hmm.controller.ControlConfig.approvalTimeOutMinutes
The com.ibm.ws.xd.hmm.controller.ControlConfig.approvalTimeOutMinutes custom property specifies the number of minutes for the approval timeout of runtime tasks for the health controller.
Set the Java™ virtual machine (JVM) custom property when you are using the supervise reaction mode. This property specifies the number of minutes that can pass before a runtime task for the health controller expires. If you set the value to 5 minutes or less, the default value of 30 minutes is automatically used instead. If you do not take any actions on the runtime task, the task expires in the number of minutes that is specified in this property. If the runtime task expires when the health condition still exists, a new runtime task is generated.
Value | Description |
---|---|
Scope | JVM |
Valid value | Minutes |
Default | 30 minutes |
maxHeapDumps
You can set the maxHeapDumps custom property to control the number of heap dumps that are taken per runtime task.
Value | Description |
---|---|
Scope | Cell |
Valid values | Integer value greater than 0 |
Default | 3 |
usexdHeapModule
You can set the usexdHeapModule custom property so that only the amount of free heap after a full garbage collection is sampled. Otherwise, the heap might include temporary Java objects.
Value | Description |
---|---|
Scope | Cell |
Valid values | true: Only the amount
of free heap after a full garbage collection is sampled. false: The amount of free heap is periodically sampled independent of the garbage collection cycle. |
Default value | false |
