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?
btw, I’ve also tried “tsd.core.meta.enable_realtime_uid = true” but not work either. However the autocomplete on grafana can show up those new tags, but the templating vars still can’t.
well, I already enable realtime_meta but still can’t retrieve those new tags in new values of existing metrics. Do you imply that it only works for new metrics?
