What kind of data can be offloaded to a central DataMiner database (MySQL, Oracle, MSSQL)? Does this include data from Cassandra only or could that also be certain data from Elastic?
Hi Thomas,
From the central database configuration you can select the following data to offload:
- Alarm data
- Real-time trend data
- Average trend data
- Snapshots of parameter values (previously configured).
The offload will include the data from the system, no matter if it is stored in cassandra, elastic, mysql or any other supported database.

Hi Thomas,
The offload data can be summarized into three different categories:
- Alarm data (info and alarm events including all their property values)
- Trend data (both realtime and average trend data)
- Parameter value data (aka parameter snapshots)
All of this offload data is populated in realtime at runtime by the DMA’s and as such doesn’t originate ever from any of our local databases.
