用户指南
Install
asadm默认在发布的安装包里，或者从github仓库获取安装
Getting Help
- Run asadm --help to learn about arguments that may be needed for your environment.
- To start the interactive shell run asadm -h [HOST_IP].
- From the Admin> prompt run help to see a complete list of supported commands.
Command Organization(组成 结构）
命令被组织成一个层次结构,类似命令共享一个共同的源(parent)。每个命令可以支持一个或多个修改，可以限制命令到一个特定的组节点或过滤一个命令的输出。
所有的命令会输出基于asadm选择为节点的节点名称。节点名称是最短的独特的前缀完全限定域名(FQDN)或或IP如果域名无法解析。 All commands will sort output based on the node name that asadm chooses for the node. The node name is the shortest unique prefix of Fully Qualified Domain Name (FQDN) or IP if the FQDN cannot be resolved.
Command Shortcuts[命令快捷键]
所有的命令都支持tab自动补全功能；在Admin>提示符,输入i 按

Modifiers
There are currently two modifiers that commands may support. 目前有两个命令可能支持的修饰符。
- like: Like shows the output containing any word listed after 'like'.
- with: With specifies a list of nodes to be used with the given command. You can use the node's IP, FQDN, or Node ID as well as any unique prefix.
Help
Admin> help info
The "info" command provides summary tables for various aspects
of Aerospike functionality.
Modifiers: with
Default: Displays service, network, namespace, and xdr summary
information.
- namespace:
Displays summary information for each namespace.
- network:
Displays network information for Aerospike, the main
purpose of this information is to link node ids to
fqdn/ip addresses.
- service:
Displays summary information for the Aerospike service.
- xdr:
Displays summary information for Cross Datacenter
Replication (XDR).

Statistics
The show statistics command displays all server statistics from several server components. By default it returns statistics from all contexts but the sub-commands bins, namespace, service, sets, and xdr will confine the output to a single context.
The following example shows batch api statistics. We can see that each node has executed more than 700,000 batch requests.
