Method Detail

init

@PostConstruct
public void init()

getContextNames

public Set<String> getContextNames()

Specified by:

getContextNames in interface MetricsService

Returns:

a set of all MetricsService.MetricsContext that currently exist. When applications are undeployed their MetricsService.MetricsContext equally are removed which means a name from the set of names returned may indeed no longer exists when using MetricsService.getContext(boolean).

getContext

public MetricsService.MetricsContext getContext(boolean createIfNotExists)

Description copied from interface: MetricsService

Access current application metric context. If this is called from a context that is not linked to an application context the server context is returned.

Specified by:

getContext in interface MetricsService

Parameters:

createIfNotExists - true to create the requested context in case it did not exist, false to instead return null in that case

Returns:

the existing or created context or null if it did not exist and parameter was false or if the servicenot MetricsService.isEnabled()

getContext

public MetricsService.MetricsContext getContext(String name)

Description copied from interface: MetricsService

Access the context by name. Implicitly creates the MetricsService.MetricsContext.SERVER_CONTEXT_NAME if needed but no other context that does not exist yet or no more.

Specified by:

getContext in interface MetricsService

Parameters:

name - the name of the MetricsService.MetricsContext to provide, this assumes it does exist

Returns:

the existing context or null if it does not (or no longer) exist. When the service not MetricsService.isEnabled() no context exists. Otherwise when asking for the MetricsService.MetricsContext.SERVER_CONTEXT_NAME the context is created should it not exist yet.

collect

public void collect(fish.payara.monitoring.collect.MonitoringDataCollector rootCollector)

Specified by:

collect in interface fish.payara.monitoring.collect.MonitoringDataSource

refresh

public void refresh()

Registers unresolved MBeans if they have been started after the metrics service.

Specified by:

refresh in interface MetricsService

isEnabled

public boolean isEnabled()

Description copied from interface: MetricsService

When metrics are disabled no MetricsService.MetricsContext exists, both MetricsService.getContext(boolean) and MetricsService.getContext(String) will return null.

Specified by:

isEnabled in interface MetricsService

Returns:

true if the metrics feature is generally enabled, else false

resetMetricsEnabledProperty

public void resetMetricsEnabledProperty()

isMetricsSecure

public Boolean isMetricsSecure()

resetMetricsSecureProperty

public void resetMetricsSecureProperty()

isSecurityEnabled

public boolean isSecurityEnabled()

registerApplication

public void registerApplication(String applicationName)

Adds an application to the enabled map

Parameters:

applicationName - The name of the application to create

deregisterApplication

public void deregisterApplication(String applicationName)

Removes an application from the enabled map

Parameters:

applicationName - The name of the application to remove

getApplicationName

public String getApplicationName()

Gets the application name from the invocation manager.

Returns:

The application name

changed

public UnprocessedChangeEvents changed(PropertyChangeEvent[] events)

Description copied from interface: ConfigListener

Notification that @Configured objects that were injected have changed

Specified by:

changed in interface ConfigListener

Parameters:

events - list of changes

Returns:

the list of unprocessed events (requiring a restart) or null if all reconfiguration was processed successfully
