[Hawkular-dev] Ability to group by datapoint tag in Grafana

[Michael Burman]

Hi,

Your syntax is still incorrect. It's either metricId or tags, not both 
(at least not in this case).

You should call /gauges/stats?tags=name:*&start=..

https://github.com/hawkular/hawkular-metrics/blob/master/api/metrics-api-jaxrs/src/main/java/org/hawkular/metrics/api/jaxrs/handler/GaugeHandler.java#L571

If you wish to use id/stats, then you can't have tags at all.

/gauges/$METRIC_ID/stats?start=..

https://github.com/hawkular/hawkular-metrics/blob/master/api/metrics-api-jaxrs/src/main/java/org/hawkular/metrics/api/jaxrs/handler/GaugeHandler.java#L509
