Class StrafePingMonitor

  • All Implemented Interfaces:
    ServiceMonitor
    @Component
public final class StrafePingMonitor
extends AbstractServiceMonitor

    This class is designed to be used by the service poller framework to test the availability of the ICMP service on remote interfaces. The class implements the ServiceMonitor interface that allows it to be used along with other plug-ins by the service poller framework.

      • poll

        public PollStatus poll​(MonitoredService svc,
                       Map<String,​Object> parameters)

        This method is the heart of the plug-in monitor. Each time an interface requires a check to be performed as defined by the scheduler the poll method is invoked. The poll is passed the service to check.

        By default when the status transition from up to down or vice versa the framework will generate an event. Additionally, if the polling interval changes due to an extended unavailability, the framework will generate an additional down event. The plug-in can suppress the generation of the default events by setting the suppress event bit in the returned integer.

        NOTE: This method may be invoked on a Minion, in which case certain bean and facilities will not be available. If any state related information is required such as agent related configuration, it should retrieved by the ServiceMonitor.getRuntimeAttributes(MonitoredService, Map).

        Poll the specified address for ICMP service availability.

        The ICMP service monitor relies on Discovery for the actual generation of IMCP 'ping' requests. A JSDT session with two channels (send/receive) is utilized for passing poll requests and receiving poll replies from discovery. All exchanges are SOAP/XML compliant.

        Parameters:
        svc - Includes details about to the service being monitored.
        parameters - Includes the service parameters defined in poller-configuration.xml and those returned by ServiceMonitor.getRuntimeAttributes(MonitoredService, Map).
        Returns:
        The availability of the interface and if a transition event should be suppressed.
