Currently there's an offload to a central database which is being planned to be used to read the real time trending.
It's been learned that the maximum resolution that DataMiner offers in the offloaded data is one measurement point per minute.
Is there a way to either offload more datapoints or to read the real time trending data directly from the Cassandra dB?
Unfortunately resolution at which RT points are offloaded into the Central DataBase is not possible. Neither from cube nor by tinkering with the files. The smallest supported resolution is 1 minute.
Polling the cassandra directly is possible if the 3rd party can utilize a cassandra driver or the CQLSH and the rights to access the database. However we would not recommend this, as this would be an unexpected load on the DB and the DB can be subject to change breaking compatability.
In the end requesting the possibility to increase the resolution as a feature seems to be the sensible approach
