Hi,

There are many databases in our production patroni cluster and it seems it is overloaded, so we decide to migrate the busiest database to a new patroni cluster. 

pgwatch2 is implemented, how to know how much CPU, RAM is used by the database please? Then we can use it to prepare the new patroni cluster hardware. Thank you

Best regards
Dennis
