InfluxDB 1.8.2 user here.  
I’ve recently found and addressed an unchecked series cardinality growth in one of our measurements. I’ve got a lovely Grafana dashboard for monitoring, however I’m unable to find instruction on the interwebs for trending the result of a “SHOW SERIES EXACT CARDINALITY” (and similar variations) over time, since “SHOW” commands are not timeseries. Has anyone accomplished this in Grafana or elsewhere? Can I “SELECT” or otherwise subquery series cardinality info from the DB?
