[jboss-jira] [JBoss JIRA] Commented: (JBAS-6808) expose cluster partition name via some ManagedObject
[

Brian Stansberry commented on JBAS-6808:
----------------------------------------
Accessing the HAPartition MOs:
There can be more than one HAPartition deployed in an AS, so we use the partitionName
property as the MO's name, i.e.
@ManagementProperty(use={ViewUse.CONFIGURATION}, description="The partition's
name")
@ManagementObjectID(type="HAPartition")
public String getPartitionName()
{
return this.partitionName;
}
So, you can't just look up the HAPartition ManagedComponent via some fixed name.
Instead, use the ComponentType:
ManagementView mgtView = getManagementView();
ComponentType type = new ComponentType("MCBean", "HAPartition");
Set<ManagedComponent> hapartitions = mgtView.getComponentsForType(type);
for (ManagedComponent mc : hapartitions)
{
System.out.println("Partition name is " +
mc.getProperty("partitionName");
}
expose cluster partition name via some ManagedObject

Key: JBAS-6808
URL: https://jira.jboss.org/jira/browse/JBAS-6808
Project: JBoss Application Server
Issue Type: Sub-task
Security Level: Public(Everyone can see)
Components: ProfileService
Affects Versions: JBossAS-5.1.0.GA
Reporter: Ian Springer
Assignee: Brian Stansberry
Priority: Critical
Fix For: JBossAS-5.2.0.Beta1
In the as4 plugin, we exposed the following trait:
<metric property="partitionName" dataType="trait"
displayType="summary"
description="the name of the cluster partition this app server
instance belongs to"/>
which we obtained via JMX as follows:
private String getPartitionName() {
ObjectNameQueryUtility queryUtility = new ObjectNameQueryUtility(
"jboss:partitionName=%partitionName%,service=DistributedReplicantManager");
try {
List<EmsBean> mBeans =
loadConnection().queryBeans(queryUtility.getTranslatedQuery());
if (mBeans.size() == 1) {
if
(queryUtility.setMatchedKeyValues(mBeans.get(0).getBeanName().getKeyProperties())) {
return
queryUtility.getVariableValues().get("partitionName");
}
}
} catch (Exception e) {
log.error("Could not load partition name as connection could not be
loaded");
}
return null;
}
We need this value exposed via some ManagedObject so we can provide the same trait in the
as5 plugin.
