By default, NetScaler pings the StorageZones Controller server to determine if it is online. However, even if the controller is online, it might not be able to send heartbeat messages to the ShareFile web site. In that case, NetScaler will send traffic to StorageZones Controller although it is not communicating with ShareFile.
To verify StorageZones Controller outbound connectivity to ShareFile, you can create a monitor that checks heartbeat.aspx and bind it to the NetScaler service for each StorageZones Controller.
add lb monitor SZC_Heartbeat HTTP-ECV -send "GET /heartbeat.aspx" -recv "***ONLINE***” -secure YES bind service StorageZone_Svc -monitorName SZC_Heartbeat
StorageZone_Svc is the NetScaler service that corresponds to a StorageZones Controller. That service name is automatically created by the NetScaler for ShareFile wizard. The service name includes the IP address of the controller, such as _SF_SVC_ip-address.
-secure YES is required if the service is listening on port 443.
