Hi. Does anyone know attribute in robot for heartbeat(primary hub down or active) time interval?
I want to reduce robot failover(primary -> secondary hub) time 10~30sec (now over 90 second)
Maybe hub_update_interval does not work in this scenario.
the value is in the robot.cfg file
this is how often the robot checks into the hub server. the hub server then adds half again if a update is missed before sending the robot inactive message.
the value is defaulted to 15 minutes (900 seconds).
we have found that if the value is set to low the hub servers start having issues keeping track of the servers and we ended up with servers being down for 3 or 4 time the interval because the hub was too busy responding to the requests to react fast enough to the missed update. once we changed the time the system was able to handle the updates fine.
we changed from 60 seconds to 120 seconds
