Also, is there a way to get metrics like number of records for a particular namespace and set across the cluster using the Python Client (example - metrics provided by ‘info set’ )? Thanks for the help.

See Client Class — Client — Aerospike documentation .

Yes, info "namespace/[NS_NAME]". Please see our metrics reference page for more .

Thanks. Can you please give an example showing which class I should use from the python client to get this info?
