Hi,

Great tool !!

I had few questions -

1. Is there a way to add additional labels that are not the column names in the table ?
   for example, can I add $HOSTNAME, $ENVIRONMENT as labels which could be exported as environment variable on the host?

2. do the meters/metric name always have to start with oracledb ? Can we rename that ?

3. Is it possible to query an external Api for metadata and merge with the SQL query to add additional labels ?
