Troubleshooting
InfluxDB: "SHOW TAG VALUES" does not support a WHERE time clause
Issue
If you use a InfluxDB Query "SHOW TAG VALUES" it returns all possible values instead of the one present in the time period selected.
There is a open GitHub "Feature Request": https://github.com/influxdata/influxdb/issues/5668
Workaround "Subquery"
SELECT "host" FROM (SELECT "<value>", "host" FROM "<InfluxDB>" WHERE $timeFilter)
host = is the tag I want to limit by time
value = is a Influx FieldKey (just needs to contain any value)
