Constructor Detail

MonitorService

public MonitorService(MonitorServiceConfiguration bootConfiguration,
                      org.jboss.as.controller.ProcessType processType)

Method Detail

getValue

public MonitorService getValue()

Specified by:

getValue in interface org.jboss.msc.value.Value<MonitorService>

getHawkularMonitorContext

public HawkularWildFlyAgentContext getHawkularMonitorContext()

Returns:

the context that can be used by others for storing ad-hoc monitoring data

addDependencies

public void addDependencies(org.jboss.msc.service.ServiceTarget target,
                            org.jboss.msc.service.ServiceBuilder<MonitorService> bldr)

When this service is being built, this method is called to allow this service to add whatever dependencies it needs.

Parameters:

target - the service target

bldr - the service builder used to add dependencies

removeInstalledServices

public void removeInstalledServices(org.jboss.as.controller.OperationContext context)

getMonitorServiceStatus

public ServiceStatus getMonitorServiceStatus()

Returns:

the status of the agent service. Will let you know if this service is started or stopped.

start

public void start(org.jboss.msc.service.StartContext startContext)
           throws org.jboss.msc.service.StartException

Specified by:

start in interface org.jboss.msc.service.Service<MonitorService>

Throws:

org.jboss.msc.service.StartException

stop

public void stop(org.jboss.msc.service.StopContext stopContext)

Specified by:

stop in interface org.jboss.msc.service.Service<MonitorService>

startMonitorService

public void startMonitorService()

Starts this service. If the service is already started, this method is a no-op.

startMonitorService

public void startMonitorService(MonitorServiceConfiguration newBootConfiguration)

Starts this service. If the service is already started, this method is a no-op.

Parameters:

newBootConfiguration - if not null is used to build the runtime configuration. Use this to reflect changes in the persisted configuration (standalone.xml) since service creation.

stopMonitorService

public void stopMonitorService()

Stops this service. If the service is already stopped, this method is a no-op.

registerFeed

public void registerFeed(String tenantId,
                         int retryMillis)
                  throws Exception

Registers the feed with the Hawkular system under the given tenant. Note, it is OK to re-register the same feed/tenant combinations. If retryMillis > 0 then this will not return until the feed is properly registered. If the Hawkular server is not up, this could mean we are stuck here for a long time.

Parameters:

tenantId - the feed is registered under the given tenantId

retryMillis - if >0 the amount of millis to elapse before retrying

Throws:

Exception - if failed to register feed

getFeedId

public String getFeedId()

Returns:

feed ID of the agent if the agent has started and the feed was registered; null otherwise

getTenantId

public String getTenantId()

Returns:

tenant ID of the agent

getSchedulerService

public SchedulerService getSchedulerService()

getLocalModelControllerClientFactory

public ModelControllerClientFactory getLocalModelControllerClientFactory()

Returns:

a factory that can create clients which can talk to the local management interface of the app server we are running in

createProtocolServicesBuilder

public ProtocolServices.Builder createProtocolServicesBuilder()

Returns:

builder that let's you create protocol services and their endpoints

getProtocolServices

public ProtocolServices getProtocolServices()

Returns:

the current set of protocol services

isImmutable

public boolean isImmutable()

Returns:

true if the agent is to be considered immutable and no config changes are allowed. This should also disallow operation execution on managed resources if those operations modify the remote resource.
