前面章节介绍了怎样查看队列、交换器、绑定关系、连接、信道和消费者状态信息。下面将介绍更多其他查看状态的命令
在 RabbitMQ 中，可以通过查看 Broker 的状态，比如当前 Erlang 节点上运行的应用程序、RabbitMQ Erlang 的版本信息、操作系统名称、内存及文件描述等统计信息。示例如下：
D:\server\rabbitmq_server-3.9.11\sbin> rabbitmqctl status
Status of node rabbit@hxstrive ...
Runtime

Listeners
Interface: [::], port: 15672, protocol: http, purpose: HTTP API
Interface: [::], port: 25672, protocol: clustering, purpose: inter-node and CLI tool communication
Interface: [::], port: 5672, protocol: amqp, purpose: AMQP 0-9-1 and AMQP 1.0
Interface: 0.0.0.0, port: 5672, protocol: amqp, purpose: AMQP 0-9-1 and AMQP 1.0我们还可以通过命令对 RabbitMQ 节点进行健康检查，确认应用是否正常运行、list_queues 和 list_channels 是否能够正常返回等等。
示例如下：
D:\server\rabbitmq_server-3.9.11\sbin> rabbitmqctl node_health_check
This command is DEPRECATED and will be removed in a future version.
It performs intrusive, opinionated health checks and requires a fully booted node.
Use one of the options covered in https://www.rabbitmq.com/monitoring.html#health-checks instead.
Timeout: 70 seconds ...
Checking health of node rabbit@hxstrive ...
16:30:58.439 [warn] rabbitmqctl node_health_check and its HTTP API counterpart are DEPRECATED. See https://www.rabbitmq.com/monitoring.html#health-checks for replacement options.
Health check passed在 RabbitMQ 中，可以通过命令显示每个运行程序环境中每个变量的名称和值。示例如下：
D:\server\rabbitmq_server-3.9.11\sbin> rabbitmqctl environment
Application environment of node rabbit@hxstrive ...
[{amqp10_common,[]},
{amqp_client,
[{prefer_ipv6,false},{ssl_options,[]},{writer_gc_threshold,1000000000}]},
{asn1,[]},
{aten,
[{detection_threshold,0.99},
{heartbeat_interval,100},
{poll_interval,5000},
{scaling_factor,1.5}]},
{compiler,[]},
{cowboy,[]},
{cowlib,[]},
...在 RabbitMQ 中，可以使用命令为所有服务器状态生成一个服务器状态报告，并将输出重定向到一个文件。示例如下：
D:\server\rabbitmq_server-3.9.11\sbin> rabbitmqctl report
Reporting server status of node rabbit@hxstrive ...
Status of node rabbit@hxstrive ...

D:\server\rabbitmq_server-3.9.11\sbin> rabbitmqctl eval "date()."
{2022,3,26}上面执行“date().”Erlang 表达式输出当前日期。
