asinfo is a command-line utility that provides an interface to Aerospike's cluster command and control functions. This includes the ability to change server configuration parameters while Aerospike is running.
Configuration changes made by
asinfo are not persisted to the Aerospike configuration file. If a change requires persistence it must be added to the configuration file.
asinfo is included in the Aerospike Tools package, and by default installs to
/usr/bin/asinfo. Use the
--help option to view
asinfo syntax and commands:

Aerospike's telnet port
Aerospike also provides a telnet service which is typically configured to port 3003. This service provides the same functionality as asinfo, once connected type the same commands you would normally pass to asinfo's -v option.
This option is not available for security enabled servers. This option can also be disabled by commenting out or removing the info stanza from aerospike.conf. It is also possible to bind this service to localhost by setting the address field to 127.0.0.1.
telnet 127.0.0.1 3003
Connected to 127.0.0.1.
Escape character is '^]'.
