Examples of org.osgi.service.monitor.MonitorAdmin

org.osgi.service.monitor.MonitorAdmin
The {@code MonitorAdmin} service is a singleton service that handles{@code StatusVariable} query requests and measurement job control requests.
Note that an alternative but not recommended way of obtaining {@code StatusVariable}s is that applications having the required {@code ServicePermissions} can query the list of {@code Monitorable} servicesfrom the service registry and then query the list of {@code StatusVariable}names from the {@code Monitorable} services. This way all services whichpublish {@code StatusVariable}s will be returned regardless of whether they do or do not hold the necessary {@code MonitorPermission} for publishing{@code StatusVariable}s. By using the {@code MonitorAdmin} to obtain the{@code StatusVariable}s it is guaranteed that only those {@code Monitorable}services will be accessed who are authorized to publish {@code StatusVariable}s. It is the responsibility of the {@code MonitorAdmin}implementation to check the required permissions and show only those variables which pass this check.
The events posted by {@code MonitorAdmin} contain the following properties:
- {@code mon.monitorable.pid}: The identifier of the {@code Monitorable}
- {@code mon.statusvariable.name}: The identifier of the {@code StatusVariable} within the given {@code Monitorable}
- {@code mon.statusvariable.value}: The value of the {@code StatusVariable}, represented as a {@code String}
- {@code mon.listener.id}: The identifier of the initiator of the monitoring job (only present if the event was generated due to a monitoring job)
Most of the methods require either a Monitorable ID or a Status Variable path parameter, the latter in [Monitorable_ID]/[StatusVariable_ID] format. These parameters must not be {@code null}, and the IDs they contain must conform to their respective definitions in {@link Monitorable} and{@link StatusVariable}. If any of the restrictions are violated, the method must throw an {@code IllegalArgumentException}. @author $Id: 40fb0b631ab04ac98c8241df0aff88ff178273b1 $
