Redundancy in module development

You need to use the Redundancy State Listener:

import com.inductiveautomation.ignition.gateway.redundancy.types.RedundancyState;
import com.inductiveautomation.ignition.gateway.redundancy.types.RedundancyStateListener;

code snippets:

   @Override
    public void redundancyStateChanged(RedundancyState redundancyState) {
        logger.debug("Redundancy State Changed to %s",redundancyState.getActivityLevel().toString());
        if(redundancyState.getActivityLevel().equals(ActivityLevel.Active)){
            this.isActive = true;
        }
        else{
            this.isActive = false;
        }
    }

    @Override
    public void redundancyConnStatusChanged(ClusterPeerConnectionStatus clusterPeerConnectionStatus) {

    }

EDIT: You have to implement the logic internally but these hooks let you know what state the Gateway is in. This works well for my SNMP Driver that I wrote.
