opHA just synchronises the information collected by NMIS9. But there are different approaches regarding opEvents data integration between servers:
Depending on the followed approach, the opEvents rules can be set up in the poller or the primary.
They should be set up in the primary in case os using the syslog approach.
If we are using the API they can be set up in the poller or the primary. It is a common approach to just send the important events to the primary.
opHA does not provide integration at the moment for opConfig.
The reports must be created from the pollers, and use local data. Then the reports can be synchronised with the primary server.
