Description

The WAN information tile on the pulse homepage displays either a green or or orange triangle indicating the status of the connection to the remote side.

That tile is populated from DistributedSystemMXBean.viewRemoteClusterStatus.

Unfortunately, that method iterators over the gateway senders of all members and adds them to a the status map by remote DS id. That means that it will only keep the connected status last sender that was added. If that last sender was a secondary, it's entirely normal that it might not be connected

  
public Map<String, Boolean> viewRemoteClusterStatus() {
    if (mapOfGatewaySenders.values().size() > 0) {
      Map<String, Boolean> senderMap = new HashMap<String, Boolean>();
      Iterator<GatewaySenderMXBean> it = mapOfGatewaySenders.values().iterator();
      while (it.hasNext()) {
        GatewaySenderMXBean bean = it.next();
        Integer dsId = bean.getRemoteDSId();
        if (dsId != null) {
          senderMap.put(dsId.toString(), bean.isConnected());
        }
...

This method should probably only look at the primary gateway sender's status.
