What is the current version of InfluxCloud?

Hi,

I have only access to InfluxCloud via Chronograf UI and I have no clue how to retrieve the current version of Influxdb I am connected to.

I am trying to run a SHOW SERIES CARDINALITY wich is available in 1.4 and as the request doesn’t work and I am trying to understand why.

Last question, I want to track the total number of series with Grafana. Is it possible to do that ?

Regards
