rabbiqmq搭建完成后，可通过web来对rabbitmq的某些指标进行监控，不过在此不予讨论。
在rabbirmq的web监控页面提供了http api监控文档。网址就是http://IP:15672/api/ 将ip换成自身主机的ip地址。
通过curl对rabbitmq进行监控，如下：

[root@crq720 ~]# curl -i -u guest:guest 'http://localhost:15672/api/overview'
HTTP/1.1 200 OK
Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
Date: Tue, 19 Jul 2016 00:59:30 GMT
Content-Type: application/json
Content-Length: 1300
Cache-Control: no-cache

{"management_version":"3.2.3","statistics_level":"fine","exchange_types":[{"name":"fanout","description":"AMQP fanout exchange, as per the AMQP specification","enabled":true},{"name":"direct","description":"AMQP direct exchange, as per the AMQP specification","enabled":true},{"name":"headers","description":"AMQP headers exchange, as per the AMQP specification","enabled":true},{"name":"topic","description":"AMQP topic exchange, as per the AMQP specification","enabled":true}],"rabbitmq_version":"3.2.3","erlang_version":"R14B04","erlang_full_version":"Erlang R14B04 (erts-5.8.5) [source] [64-bit] [rq:1] [async-threads:30] [kernel-poll:true]","message_stats":{},"queue_totals":{"messages":0,"messages_details":{"rate":0.0},"messages_ready":0,"messages_ready_details":{"rate":0.0},"messages_unacknowledged":0,"messages_unacknowledged_details":{"rate":0.0}},"object_totals":{"consumers":0,"queues":1,"exchanges":15,"connections":0,"channels":0},"node":"rabbit@crq720","statistics_db_node":"rabbit@crq720","listeners":[{"node":"rabbit@crq720","protocol":"amqp","ip_address":"::","port":5672}],"contexts":[{"node":"rabbit@crq720","description":"RabbitMQ Management","path":"/","port":15672},{"node":"rabbit@crq720","description":"Redirect to port 15672","path":"/","port":55672,"ignore_in_use":true}]}

如上所示，使用curl -i -u guest:guest ‘http://localhost:15672/api/overview‘得到的是rabbitmq的web页面的overview的信息。

[root@crq720 ~]# curl -i -u guest:guest 'http://localhost:15672/api/queues/%2Fudc_host/udc_queue'
HTTP/1.1 200 OK
Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)

如上所示，使用curl -i -u guest:guest ‘http://localhost:15672/api/queues/%2Fudc_host/udc_queue‘所得到的是Virtual host为/udc_host，quene为udc_queue的queue信息。在此／在url中的转义字符为％2F。
如上，可通过crul获得想要监控的信息，想监控更多内容，就去查API文档吧。
在此我最想说的是我通过curl获取的信息，太难看，如果显示的效果是树状形式就好了，可惜我并没有找到curl的信息格式化的内容，在此，我便使用了python脚本来进行监控：

import sys, json, urllib, base64, socket,httplib

server = '172.16.17.128'
port = '15672'
vhost = '/udc_host'
username = 'guest'
password = 'guest'
queue_name = 'udc_queue'

conn = httplib.HTTPConnection(server, port)

path = "/api/queues/%s/%s" % (urllib.quote(vhost, safe=""),
                              queue_name)
method = "GET"

credentials = base64.b64encode("%s:%s" % (username, password))
conn.request(method, path, "",
                 {"Content-Type" : "application/json",
                  "Authorization" : "Basic " + credentials})

response = conn.getresponse()
resp_payload = json.loads(response.read())
resp_payload = json.dumps(resp_payload,indent = 4)

print resp_payload

如上代码是根据书籍《rabbitmq in action》进行修改的，在此，简化了些代码，方便理解。如上的代码片段显示效果如下：

{
    "node": "rabbit@crq720", 
    "auto_delete": false, 
    "deliveries": [], 
    "idle_since": "2016-06-28 8:01:57", 
    "messages_unacknowledged": 0, 
    "consumers": 0, 
    "durable": true, 
    "arguments": {}, 
    "memory": 13704, 
    "exclusive_consumer_tag": "", 
    "messages_ready_details": {
        "rate": 0.0
    }, 
    "status": "running", 
    "messages_details": {
        "rate": 0.0
    }, 
    "vhost": "/udc_host", 
    "consumer_details": [], 
    "messages_unacknowledged_details": {
        "rate": 0.0
    }, 
    "incoming": [], 
    "name": "udc_queue", 
    "policy": "", 
    "backing_queue_status": {
        "q1": 0, 
        "q3": 0, 
        "q2": 0, 
        "q4": 0, 
        "avg_ack_egress_rate": 0.0, 
        "ram_msg_count": 0, 
        "ram_ack_count": 0, 
        "len": 0, 
        "persistent_count": 0, 
        "target_ram_count": "infinity", 
        "next_seq_id": 0, 
        "delta": [
            "delta", 
            "undefined", 
            0, 
            "undefined"
        ], 
        "pending_acks": 0, 
        "avg_ack_ingress_rate": 0.0, 
        "avg_egress_rate": 0.0, 
        "avg_ingress_rate": 0.0
    }, 
    "messages": 0, 
    "messages_ready": 0
}

在此以树状形式展现更方便自己选取监控指标，也方便改写代码在nagios和collectd中进行监控。
