In case of a Dataminer cluster with an Elasticsearch DB, is it possible to use external tool such as Grafana to display metrics extracted from Elastic DB?

Hi Bernard,
Out of the box, Grafana supports integrating data from an Elasticsearch db, so the short answer is 'Yes'.
A few considerations have to be made though.
- The DataMiner Elasticsearch db is actively used by DataMiner for both storage as well as retrieval of data. This means that letting an external application - such as Grafana - interface with the Elasticsearch db, could have an impact on DataMiner performance. Caution is advised.
- Not sure what kind of data you plan to visualize in Grafana, but keep in mind that performance data (historical trend points) is not stored by DataMiner in the Elasticsearch db. For that, we use Cassandra.

Hi,
I’d like to add one additional remark.
The structure of the data in the Elasticsearch is managed by DataMiner.
Meaning that between DataMiner versions this structure could change to serve the needs of our core software, as such this is not something we can guarantee backwards compatibility on between feature releases.
