Sensor Factory with Cluster, failover data not read

Good Afternoon all,

I have a 2-node cluster, East (primary) and West (failover). I also have a number of external remote probes in AWS. I have created a Sensor Factory that looks at a sensor in each of my AWS Probes with the sensor set for AWS1 AND AWS2, where aws1 and aws2 must be down for the Factory Sensor to alarm as down. I've completed that successfully and now I want to bring up the sensor factory on my West failover node. It is present and the sensor factory is reporting up, however the icon is grey with '?' and the error states :

Unknown - All source channels have no data.

My cluster nodes are connected via DNS hostnames, all resolve correctly, and the external probes have static NAT rules and hostnames that correctly resolve to the Public IP's.

Hi there,

Please make sure that all sensors used in the Factory Sensor and the Factory Sensor itself are having the same scanning interval. Is this the case?

Best regards.

Actually, I resolved the issue 10 minutes after submitting the OP. My public dns address was not entered correctly. Once I fixed this then both sensors went green. Thanks for the timely response!
