As RRD data is not synchronised, opCharts makes a remote call to visualise the graph information. If you cannot see the graphs, please review this information.
opHA just synchronises the information collected by NMIS9. But there are different approaches regarding opEvents data integration:
opConfig will work just with local nodes.
opHA does not provide integration at the moment for opReports.
As opReports uses rrd data and this is not synchronised.
The reports must be created from the pollers, and use local data.
