RabbitMQ监控

RabbitMQ的使用中常常会出现队列积压等问题,这时就需要监控connection、channel、queue等状态。

RabbitMQ包含了监控插件,通过命令rabbitmq-plugins enable rabbitmq_management可以启用,通过15672端口可以访问。

在浏览器中可以直接使用界面交互,很容易看到各种属性的状况,一般使用guest/guest登录即可:

如果我们想在程序中集成mq监控,则可以使用Rabbitmq的API获取各个属性的数据。

RabbitMQ Management HTTP API

Introduction

Apart from this help page, all URIs will serve only resources of type   application/json , and will require HTTP basic authentication (using the standard RabbitMQ user database). The default user is guest/guest.
Many URIs require the name of a virtual host as part of the path, since names only uniquely identify objects within a virtual host. As the default virtual host is called " / ", this will need to be encoded as " %2f ".
PUTing a resource creates it. The JSON object you upload must have certain mandatory keys (documented below) and may have optional keys. Other keys are ignored. Missing mandatory keys constitute an error.
Since bindings do not have names or IDs in AMQP we synthesise one based on all its properties. Since predicting this name is hard in the general case, you can also create bindings by POSTing to a factory URI. See the example below.
Many URIs return lists. Such URIs can have the query string parameters   sort   and   sort_reverse   added.   sort   allows you to select a primary field to sort by, and   sort_reverse   will reverse the sort order if set to   true . The   sort   parameter can contain subfields separated by dots. This allows you to sort by a nested component of the listed items; it does not allow you to sort by more than one field. See the example below.
You can also restrict what information is returned per item with the   columns   parameter. This is a comma-separated list of subfields separated by dots. See the example below.
Most of the GET queries return many fields per object. See   the separate stats documentation .

Examples

A few quick examples for Windows and Unix, using the command line tool   curl :
  • Get a list of vhosts:
    :: Windows
    C:\> curl -i -u guest:guest http://localhost:15672/api/vhosts

    # Unix
    $ curl -i -u guest:guest http://localhost:15672/api/vhosts

    HTTP/1.1 200 OK
    Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
    Date: Mon, 16 Sep 2013 12:00:02 GMT
    Content-Type: application/json
    Content-Length: 30

    [{"name":"/","tracing":false}]
  • Get a list of channels, fast publishers first, restricting the info items we get back:
    :: Windows
    C:\> curl -i -u guest:guest "http://localhost:15672/api/channels?sort=message_stats.publish_details.rate&sort_reverse=true&columns=name,message_stats.publish_details.rate,message_stats.deliver_get_details.rate"

    # Unix
    $ curl -i -u guest:guest 'http://localhost:15672/api/channels?sort=message_stats.publish_details.rate&sort_reverse=true&columns=name,message_stats.publish_details.rate,message_stats.deliver_get_details.rate'

    HTTP/1.1 200 OK
    Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
    Date: Mon, 16 Sep 2013 12:01:17 GMT
    Content-Type: application/json
    Content-Length: 219
    Cache-Control: no-cache

    [{"message_stats":{"publish_details":{"rate" ... (remainder elided)
  • Create a new vhost:
    :: Windows
    C:\> curl -i -u guest:guest -H "content-type:application/json" ^
    -XPUT http://localhost:15672/api/vhosts/foo

    # Unix
    $ curl -i -u guest:guest -H "content-type:application/json" \
    -XPUT http://localhost:15672/api/vhosts/foo

    HTTP/1.1 204 No Content
    Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
    Date: Mon, 16 Sep 2013 12:03:00 GMT
    Content-Type: application/json
    Content-Length: 0

    Note: you must specify application/json as the mime type.
    Note: the name of the object is not needed in the JSON object uploaded, since it is in the URI. As a virtual host has no properties apart from its name, this means you do not need to specify a body at all!
  • Create a new exchange in the default virtual host:
    :: Windows
    C:\> curl -i -u guest:guest -H "content-type:application/json" ^
    -XPUT -d"{""type"":""direct"",""durable"":true}" ^
    http://localhost:15672/api/exchanges/%2f/my-new-exchange

    # Unix
    $ curl -i -u guest:guest -H "content-type:application/json" \
    -XPUT -d'{"type":"direct","durable":true}' \
    http://localhost:15672/api/exchanges/%2f/my-new-exchange

    HTTP/1.1 204 No Content
    Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
    Date: Mon, 16 Sep 2013 12:04:00 GMT
    Content-Type: application/json
    Content-Length: 0

    Note: we never return a body in response to a PUT or DELETE, unless it fails.
  • And delete it again:
    :: Windows
    C:\> curl -i -u guest:guest -H "content-type:application/json" ^
    -XDELETE http://localhost:15672/api/exchanges/%2f/my-new-exchange

    # Unix
    $ curl -i -u guest:guest -H "content-type:application/json" \
    -XDELETE http://localhost:15672/api/exchanges/%2f/my-new-exchange

    HTTP/1.1 204 No Content
    Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
    Date: Mon, 16 Sep 2013 12:05:30 GMT
    Content-Type: application/json
    Content-Length: 0

The server definitions - exchanges, queues, bindings, users, virtual hosts, permissions and parameters. Everything apart from messages. POST to upload an existing set of definitions. Note that:
  • The definitions are merged. Anything already existing on the server but not in the uploaded definitions is untouched.
  • Conflicting definitions on immutable objects (exchanges, queues and bindings) will cause an error.
  • Conflicting definitions on mutable objects will cause the object in the server to be overwritten with the object from the definitions.
  • In the event of an error you will be left with a part-applied set of definitions.
For convenience you may upload a file from a browser to this URI (i.e. you can use  multipart/form-data  as well as  application/json ) in which case the definitions should be uploaded as a form field named "file".

X
X
 
/api/exchanges/ vhost / name
An individual exchange. To PUT an exchange, you will need a body looking something like this:
{"type":"direct","auto_delete":false,"durable":true,"internal":false,"arguments":{}}
The  type  key is mandatory; other keys are optional.
When DELETEing an exchange you can add the query string parameter   if-unused=true . This prevents the delete from succeeding if the exchange is bound to a queue or as a source to another exchange.
X
     
/api/exchanges/ vhost / name /bindings/source
A list of all bindings in which a given exchange is the source.
X
     
/api/exchanges/ vhost / name /bindings/destination
A list of all bindings in which a given exchange is the destination.
     
X
/api/exchanges/ vhost / name /publish
Publish a message to a given exchange. You will need a body looking something like:
{"properties":{},"routing_key":"my key","payload":"my body","payload_encoding":"string"}
All keys are mandatory. The  payload_encoding  key should be either "string" (in which case the payload will be taken to be the UTF-8 encoding of the payload field) or "base64" (in which case the payload field is taken to be base64 encoded).
If the message is published successfully, the response will look like:
{"routed": true}
routed  will be true if the message was sent to at least one queue.
Please note that the HTTP API is not ideal for high performance publishing; the need to create a new TCP connection for each message published can limit message throughput compared to AMQP or other protocols using long-lived connections.
X
     
/api/queues
A list of all queues.
X
     
/api/queues/ vhost
A list of all queues in a given virtual host.
X
X
X
 
/api/queues/ vhost / name
An individual queue. To PUT a queue, you will need a body looking something like this:
{"auto_delete":false,"durable":true,"arguments":{},"node":"rabbit@smacmullen"}
All keys are optional.
When DELETEing a queue you can add the query string parameters   if-empty=true   and / or   if-unused=true . These prevent the delete from succeeding if the queue contains messages, or has consumers, respectively.
X
     
/api/queues/ vhost / name /bindings
A list of all bindings on a given queue.
   
X
 
/api/queues/ vhost / name /contents
Contents of a queue. DELETE to purge. Note you can't GET this.
     
X
/api/queues/ vhost / name /actions
Actions that can be taken on a queue. POST a body like:
{"action":"sync"}
Currently the actions which are supported are  sync  and  cancel_sync .
     
X
/api/queues/ vhost / name /get
Get messages from a queue. (This is not an HTTP GET as it will alter the state of the queue.) You should post a body looking like:
{"count":5,"requeue":true,"encoding":"auto","truncate":50000}
  • count controls the maximum number of messages to get. You may get fewer messages than this if the queue cannot immediately provide them.
  • requeue determines whether the messages will be removed from the queue. If requeue is true they will be requeued - but their redelivered flag will be set.
  • encoding must be either "auto" (in which case the payload will be returned as a string if it is valid UTF-8, and base64 encoded otherwise), or "base64" (in which case the payload will always be base64 encoded).
  • If truncate is present it will truncate the message payload if it is larger than the size given (in bytes).
truncate   is optional; all other keys are mandatory.
Please note that the get path in the HTTP API is intended for diagnostics etc - it does not implement reliable delivery and so should be treated as a sysadmin's tool rather than a general API for messaging.
X
     
/api/bindings
A list of all bindings.
X
     
/api/bindings/ vhost
A list of all bindings in a given virtual host.
X
   
X
/api/bindings/ vhost /e/ exchange /q/ queue

To create a new binding, POST to this URI. Request body should be a JSON object optionally containing two fields,   routing_key   (a string) and   arguments   (a map of optional arguments):
{"routing_key":"my_routing_key", "arguments":{"x-arg": "value"}}
All keys are optional. The response will contain a  Location  header telling you the URI of your new binding.
X
 
X
 
/api/bindings/ vhost /e/ exchange /q/ queue / props

X
   
X
/api/bindings/ vhost /e/ source /e/ destination
A list of all bindings between two exchanges, similar to the list of all bindings between an exchange and a queue, above.
To create a new binding, POST to this URI. Request body should be a JSON object optionally containing two fields,   routing_key   (a string) and   arguments   (a map of optional arguments):
{"routing_key":"my_routing_key", "arguments":{"x-arg": "value"}}
All keys are optional. The response will contain a  Location  header telling you the URI of your new binding.
X

X
     
/api/vhosts
A list of all vhosts.
X
X
