How does the ES determine whether an AS is online?
- Enterprise Server
- Automation Server
An AS behaves as if it is online yet shows up as offline in Workstation.
As of 188.8.131.5201 there is a new model for detecting online / online servers.
Prior to 184.108.40.20601
- When a communication error was detected the Automation Server was marked as offline.
As of 220.127.116.1101
- An immediate DetectOnline call is scheduled.
- Only after three failed DetectOnline with an interval of one second we consider the server to be offline.
- When offline an alarm is generated.and set the offline status as normal, and also go back to one minute interval for online detection.
In 18.104.22.16801 the number of retries and interval is possible to set in server.properties.
From 1.6.0 this is configurable from WorkStation.
