From the docs, if we give server list in comma separated fashion, the data will be load balanced between two receivers. Please confirm if my understanding is correct.
# Specify a target group made up of two receivers. In this case, the data will
# be distributed using AutoLB between these two receivers. You can specify as
# many receivers as you wish here. You can combine host name and IP if you
# wish.
# NOTE: Do not use this configuration with SplunkLightForwarder.
