InfluxDB: Query From Multiple Series

I have an influxdb instance, in which an upstream server is logging measurements into. I have multiple series of the shape: web.[domain].[status], for example: web.www.foobar.com.2xx, web.www.quux.com.3xx etc. There are two "variables" encoded into the series name: the domain and the status (2xx, 3xx, etc. are already aggregated).

Now I'd like to see how many of those requests I get. One possibility would be to just list the series:

select sum("value") from "web.www.quux.com.2xx","web.www.quux.com.3xx",...

But this is neither practical (too many) nor actually feasible (new domains are added and removed all the time), so I need a more flexible approach.

Is there some kind of wildcard syntax allowed in the from clause? The documentation doesn't mention any. Or is there another way to approach this?

You should to avoid this kind of measurement naming convention:

https://docs.influxdata.com/influxdb/v1.8/concepts/schema_and_data_layout/#avoid-encoding-data-in-measurement-names

hAvoid encoding data in measurement names

InfluxDB queries merge data that falls within the same measurement; it’s better to differentiate data with tags than with detailed measurement names. If you encode data in a measurement name, you must use a regular expression to query the data, making some queries more complicated or impossible.
