Synopsis
qb_supervisor = supervisor qb_supervisor = supervisor, supervisor…
A comma-separated list of Supervisor hosts which the client applications will access for information about the queue.
In the absence of a qb_supervisor value, workers and clients will resort to "supervisor auto-discovery" and attempt to find a supervisor by network broadcast.
About supervisor auto-discovery
Qube workers that don't have the supervisor explicitly defined via the qb_supervisor value can issue a broadcast across the network and ask any supervisor that's running to respond. This is normally sufficient unless there are multiple supervisors on the network that can respond to the broadcast (on the same IP subnet as the worker). In this case, the qb_domain value provides a check for the auto-discovery mechanism: the qb_domain value is compared between the supervisor and the worker, and the supervisor only responds to requests from workers whose qb_domain value matches the supervisor's.
Example
qb_supervisor = sv001,sv002qb_supervisor = supervisor
Defaults
(empty – Automatically detected)
Notes
- Although Qube supports auto-detection of its Supervisor on the same subnet, it is more efficient if the Supervisor has been explicitly specified. The clients will always default to auto-detection if blank.
- This parameter is only applicable for the Worker or Client.
