Thank you all again.
I take this opportunity to share with you what we are doing here at
ArcelorMittal AMERICAS.
We are using to paths for sensor data :
1) OPC UA Server -> miNiFi -> NiFi -> HBase/HDFS Parquet -> Spark for further
analysis.
2) OPC UA Server -> miNiFi -> NiFi -> Microsoft Power BI for real-time
dashboards and reports.
Some data sensors also can be submited using MQTT -> NiFi …..
What we are trying to do. Replace the HBase/HDFS for IOTDB and add Grafana as
an alternative to Power BI.
I’ve seen you talking about miNiFi/NiFi support and improve Grafana connection,
these are a very important integrations to us.
Until the NiFi integration becomes available, I will follow your recommendation
: OPC UA Server -> miNiFi -> NiFi -> SPARK -> TSFILE -> Script > IOTDB > Grafana
As soon as you release the version 0.10 I will upgrade to take the benefits
that you mention.
Once again, thank you all.
