Aerospike Information Tool (asinfo)

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:

asinfo --help

asinfo can be configured with the tools configuration files. The following summary explains all configuration options. Refer to Aerospike Tools Configuration for more details.

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


telnet 3003
Connected to
Escape character is '^]'.
