一、日志和监控
RabbitMQ日志存放目录
[root@localhost ~]# ll /var/log/rabbitmq/ 总用量 176 -rw-r-----. 1 rabbitmq rabbitmq 177947 10月 10 10:21 rabbit@localhost.log -rw-r-----. 1 rabbitmq rabbitmq 0 10月 6 11:35 rabbit@localhost_upgrade.log [root@localhost ~]#
其中 rabbit@localhost.log 是默认日志
就是跑了视频的一些案例，查看下这个日志大小：
[root@localhost ~]# ll -h /var/log/rabbitmq/rabbit@localhost.log -rw-r-----. 1 rabbitmq rabbitmq 174K 10月 10 10:21 /var/log/rabbitmq/rabbit@localhost.log [root@localhost ~]#
查看日志：
[root@localhost ~]# cat /var/log/rabbitmq/rabbit@localhost.log
一部分日志信息：

二、消息追踪
一、追踪原理概述：
大概意思是，追踪的技术层面实现还是依靠这个队列和交换机，这个交换机和队列不是为了生产和业务应用
专门用于记录其他队列的工作情况。
Firehose功能
每个虚拟主机下的交换机都会默认创建一个Trace交换机：
交换机属性：
TOPIC通配符模式
持久化 是
内部使用 是
在 / 虚拟主机下创建一个监控队列（使用#路由分配 来监听所有队列）
将队列绑定到trace交换机上
在队列中发送一条消息测试：
我这多点了2条
https://www.pianshen.com/article/50101743795/
这里可以先查看下Trace功能的状态：
[root@localhost ~]# rabbitmq-plugins list Listing plugins with pattern ".*" ... Configured: E = explicitly enabled; e = implicitly enabled | Status: * = running on rabbit@localhost |/ [ ] rabbitmq_amqp1_0 3.9.7 [ ] rabbitmq_auth_backend_cache 3.9.7 [ ] rabbitmq_auth_backend_http 3.9.7 [ ] rabbitmq_auth_backend_ldap 3.9.7 [ ] rabbitmq_auth_backend_oauth2 3.9.7 [ ] rabbitmq_auth_mechanism_ssl 3.9.7 [ ] rabbitmq_consistent_hash_exchange 3.9.7 [ ] rabbitmq_event_exchange 3.9.7 [ ] rabbitmq_federation 3.9.7 [ ] rabbitmq_federation_management 3.9.7 [ ] rabbitmq_jms_topic_exchange 3.9.7 [E*] rabbitmq_management 3.9.7 [e*] rabbitmq_management_agent 3.9.7 [ ] rabbitmq_mqtt 3.9.7 [ ] rabbitmq_peer_discovery_aws 3.9.7 [ ] rabbitmq_peer_discovery_common 3.9.7 [ ] rabbitmq_peer_discovery_consul 3.9.7 [ ] rabbitmq_peer_discovery_etcd 3.9.7 [ ] rabbitmq_peer_discovery_k8s 3.9.7 [ ] rabbitmq_prometheus 3.9.7 [ ] rabbitmq_random_exchange 3.9.7 [ ] rabbitmq_recent_history_exchange 3.9.7 [ ] rabbitmq_sharding 3.9.7 [ ] rabbitmq_shovel 3.9.7 [ ] rabbitmq_shovel_management 3.9.7 [ ] rabbitmq_stomp 3.9.7 [ ] rabbitmq_stream 3.9.7 [ ] rabbitmq_stream_management 3.9.7 [ ] rabbitmq_top 3.9.7 [ ] rabbitmq_tracing 3.9.7 [ ] rabbitmq_trust_store 3.9.7 [e*] rabbitmq_web_dispatch 3.9.7 [ ] rabbitmq_web_mqtt 3.9.7 [ ] rabbitmq_web_mqtt_examples 3.9.7 [ ] rabbitmq_web_stomp 3.9.7 [ ] rabbitmq_web_stomp_examples 3.9.7 [root@localhost ~]#
应该是这个tracing功能，可以看见标识为 未启用的状态
现在把他打开：
[root@localhost ~]# rabbitmq-plugins enable rabbitmq_tracing Enabling plugins on node rabbit@localhost: rabbitmq_tracing The following plugins have been configured: rabbitmq_management rabbitmq_management_agent rabbitmq_tracing rabbitmq_web_dispatch Applying plugin configuration to rabbit@localhost... The following plugins have been enabled: rabbitmq_tracing started 1 plugins. [root@localhost ~]#
然后设置trace为on
注意下面的输出，它是默认给 / 的虚拟主机添加的
[root@localhost ~]# rabbitmqctl trace_on Starting tracing for vhost "/" ... Trace enabled for vhost / [root@localhost ~]#
如果添加到其他虚拟主机，则是：
-p 参数前缀 加上你的虚拟主机名字
rabbitmqctl trace_on -p myhost
现在再次发送消息：
开启后的消息明显和之前的不一样，会提供详细的信息：
查询全部消息，会发现，会有其他交换机也发送消息：
原来上面的那条是trace帮我发送的，下面的才是我自己发送的
关闭trace功能：
同样如果是其他虚拟主机，加-p前缀 带上主机名称
[root@localhost ~]# rabbitmqctl trace_off Stopping tracing for vhost "/" ... Trace disabled for vhost / [root@localhost ~]#
我发现是我眼睛瞎了？？？
从【Admin】标签点进去是找不到Tracing功能的
然后又从头上那个 【Cluster】集群主机名点进去，这个Tracing功能才给我展示出来
现在新增一个追踪队列（使用Trace面板）：
添加之后，会生成一个队列和一个日志：
访问日志文件需要用户授权，输入账号密码访问：
队列是一个专门追踪的队列
现在在之前测试的队列中发送消息 （test-trace-Q）：
再回去看日志文件
日志信息：
================================================================================ 2021-10-10 3:47:12:050: Message published Node: rabbit@localhost Connection: <rabbit@localhost.1633827853.14098.0> Virtual host: / User: test Channel: 1 Exchange: Routing keys: [<<"test-trace-Q">>] Routed queues: [<<"test-trace-Q">>] Properties: [{<<"delivery_mode">>,signedint,1},{<<"headers">>,table,[]}] Payload: tracing-panel-function-test, message send.... ================================================================================ 2021-10-10 3:49:10:117: Message published Node: rabbit@localhost Connection: <rabbit@localhost.1633827853.14360.0> Virtual host: / User: test Channel: 1 Exchange: Routing keys: [<<"test-trace-Q">>] Routed queues: [<<"test-trace-Q">>] Properties: [{<<"delivery_mode">>,signedint,1},{<<"headers">>,table,[]}] Payload: second message send...
Tracing面板上点击Stop,队列就会被移除，再点击Delete就删除了日志文件
