Where I can find info below in 2.0, 2.2 documentations ?
https://www.zabbix.com/documentation/1.8/manual/distributed_monitoring/data_flow

Seems https://www.zabbix.com/documentation/2.0/contrib/18_transfer_status is inconsistent because "15. Distributed Monitoring" section is empty at all. But some part apparently has been copied to 2.0 doc in the past: https://www.zabbix.com/documentation/2.0/manual/distributed_monitoring/nodes

How can I be sure that we didn't lost any other important documentation part which we were collecting during years ?
