Hi guys, I just followed the guide in http://docs.grafana.org/features/datasources/opentsdb/#templating-queries:
If you do not see template variables being populated in Preview of values section, you need to enable tsd.core.meta.enable_realtime_ts in the OpenTSDB server settings.
I was using tag_values() to query all tags with “tsd.core.meta.enable_realtime_ts = true” enabled in openTSDB. But the new tags still didn’t show up on grafana. I have to manually run “tsdb uid metasync” to work around it. What I am missing here?
