An F5 load-balancer was setup and should be sending syslog traffic to some Cribl Stream workers using round-robin. Currently there is a single source of events, for testing purposes. The events are almost exclusively going to a single worker, which is unexpected.
The expectation is that the events would be load-balanced and that there would be a fair distribution across the worker nodes. According to F5 team, the connection gets load-balanced, so as more sources added, traffic will start showing on the other workers. That is to be expected but since UDP syslog is being used the events from a single source should already getting load balanced.
