This issue is fixed in the current ONMS Grafana data source.
Good night and good luck.

I propose closing this issue as the limitation of 10 nodes returned by grafana-opennms-datasource does not occur in datasource 2.1.0 with Horizon 20.0.0 and grafana 4.3.1. I have tested with up to 400 nodes with no problem. Whatever the real limit is now should be noted in the non-existent datasource document.
grafana opennms datasource query returns incorrect values.
Start with query that correctly returns all selected nodes:
Now add another pattern matching eight (8) nodes to the query:
Not only does it not find all 8 grus nodes, it no longer returns all hellboys!
Removing everything except grus% from the query correctly returns all 8 of them!
It seems the query result is limited to a maximum of ten (10). No matter how many nodes match the query, only a maximum of 10 will be returned.
