      Description

      When you use Cortex or InfluxDB and you collect performance metrics with a higher resolution of 5 minutes (300s), it is not possible to query metrics in a higher resolution. In the Grafana data source, I've configured a Min time interval of 15s.

      In Grafana the request is made with a step size of 15000ms but in the response shows a step size of 300000ms and the min time interval is ignored.

      To rule this out, I've configured on the OpenNMS side

      org.opennms.newts.query.minimum_step=15000
      

      even it has nothing to do with Newts, but it doesn't solve the problem. I've tried Cortex and the Influx 2.0 data source with the same effects.
