Start payload test.
corosync-pload starts the pload service. This is used as a test tool to generate traffic. All nodes will begin transmitting messages and they will stop when 1500000 messages have been received per node.
To view the progress of this execute:
$ corosync-objctl runtime.services.pload.
At the end of the run a log message will be written showing the number of messages written and the time that this took.
corosync: [PLOAD ] 1500000 Writes 300 bytes per write 30.838 seconds runtime, 48640.968 TP/S, 13.916 MB/S.
