- com.google.common.util.concurrent.AbstractIdleService
- - org.somda.sdc.glue.consumer.SdcRemoteDeviceWatchdog

All Implemented Interfaces:

com.google.common.util.concurrent.Service
```
public class SdcRemoteDeviceWatchdog
extends com.google.common.util.concurrent.AbstractIdleService
```
Sends WS-Eventing Renew or DirectedProbe requests and informs in case of an error.
SdcRemoteDeviceWatchdog is a Guava service that requests a remote device in a given periodicity once started.
- If at least one subscription exists, SdcRemoteDeviceWatchdog tries to renew this subscription in order to check if the remote device is still reachable.
- If multiple subscriptions exist, all are renewed.
- If no subscription exists, SdcRemoteDeviceWatchdog sends a directed probe.
The automatic renew spares enabling auto-renew for subscriptions. The requested expires value for Subscribe requests is ConsumerConfig#WATCHDOG_PERIOD * 3.
Watchdog events are distributed only if the service is running.
