Once the service has been started, a quick view of the service status can be determined using trepctl. Because there are multiple services, the service name and host name must be specified explicitly. The Extractor connection of one of the fan-in hosts:

shell> trepctl -service alpha -host host1 status

Note that because this is a fan-in topology, the sequence numbers and applied sequence numbers will be different for each service, as each service is independently storing data within the fan-in hub database.

The following sequence number combinations should match between the different hosts on each service:

The sequence numbers between host1 and host2 will not match, as they are two independent services.
