I guess it would depend on the use case, and what data you would be interested in (e.g. alarm data to show statistics, trend performance data, real-time data).

Possibly the offload function of DataMiner could be considered here.  Offload database | DataMiner Docs.  It allows one to offload both alarm data as well as trend data.  This can go into various SQL stores, or plain files, and that could be loaded into Google Looker.
