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

[Gareth Healy]

Hi John S,

No, still dont get any data (204 error) back with that endpoint either.

I tweaked the endpoint, as you had /stats/tags/*type*/ - presume that was a
typo, since it gives me a 404 and i can't see it mentioned in the docs so
just removed it.

HAWKULAR_TENANT="fis2-monitoring-demo"
MERTIC_ID="pod%2Fded071be-d9a6-11e6-8140-525400c583ad%2Fcustom%2Fprometheus_MyCamel_MeanProcessingTime"

curl -v -k -X GET \

-H "Content-Type: application/json" \

-H "Hawkular-Tenant: $HAWKULAR_TENANT" \

-H "Authorization: Bearer $(oc sa get-token -n openshift-infra heapster)" \

"$HAWKULAR_URL/gauges/$MERTIC_ID/stats/tags/name:*?start=1484320827578&
end=1484329973940"

Tried with both tag keys (name and type) and with the value set and
wild-carded.

The $HAWKULAR_URL/gauges/$MERTIC_ID/raw endpoint returns data points.
