The command setPartitionCount tells the aggregator server how many partitions to keep PMI statistics for in the bulletin board. For example, if there are 10,000 partitions in the cluster, and the aggregator partition count is set to 20, the top 20 partitions in terms of transaction count and response times will be stored in the bulletin board.
--id Specifies which subscription to update the partition count.
Usage: ./wpfadmin setPartitionCount 6 --id 12
