rabbitmqctl


rabbitmqctl start_app
rabbitmqctl stop_app
rabbitmqctl list_exchanges
rabbitmqctl list_queues
rabbitmqctl list_consumers
rabbitmqctl list_vhosts
rabbitmqctl cluster_status
rabbitmqctl status 查看RabbitMQ版本，3.2.4


Usage:
rabbitmqctl [-n <node>] [-q] <command> [<command options>] 


Options:
    -n node
    -q


Default node is "rabbit@server", where server is the local host. On a host 
named "server.example.com", the node name of the RabbitMQ Erlang node will 
usually be rabbit@server (unless RABBITMQ_NODENAME has been set to some 
non-default value at broker startup time). The output of hostname -s is usually 
the correct suffix to use after the "@" sign. See rabbitmq-server(1) for 
details of configuring the RabbitMQ broker.


Quiet output mode is selected with the "-q" flag. Informational messages are 
suppressed when quiet mode is in effect.

    stop [<pid_file>]
    stop_app

<vhostinfoitem> must be a member of the list [name, tracing].


The list_queues, list_exchanges and list_bindings commands accept an optional 
virtual host parameter for which to display results. The default value is "/".


<queueinfoitem> must be a member of the list [name, durable, auto_delete, 
arguments, policy, pid, owner_pid, exclusive_consumer_pid, 
exclusive_consumer_tag, messages_ready, messages_unacknowledged, messages, 
consumers, memory, slave_pids, synchronised_slave_pids, status].


<exchangeinfoitem> must be a member of the list [name, type, durable, 
auto_delete, internal, arguments, policy].


<bindinginfoitem> must be a member of the list [source_name, source_kind, 
destination_name, destination_kind, routing_key, arguments].


<connectioninfoitem> must be a member of the list [pid, name, port, host, 
peer_port, peer_host, ssl, ssl_protocol, ssl_key_exchange, ssl_cipher, 
ssl_hash, peer_cert_subject, peer_cert_issuer, peer_cert_validity, 
last_blocked_by, last_blocked_age, state, channels, protocol, auth_mechanism, 
user, vhost, timeout, frame_max, client_properties, recv_oct, recv_cnt, 
send_oct, send_cnt, send_pend].


<channelinfoitem> must be a member of the list [pid, connection, name, number, 
user, vhost, transactional, confirm, consumer_count, messages_unacknowledged, 
messages_uncommitted, acks_uncommitted, messages_unconfirmed, prefetch_count, 
client_flow_blocked].

队列监控：
创建test13，首先会调用nova-scheduler进行调度，因此需要监控scheduler.ly-controller队列，然后test13会部署在ly-compute2上，因此需要监控compute.ly-compute2队列
队列 连接 监控方法监控网卡
scheduler.ly-controller ly-controller:60917需要在ly-controller主机上进行Wireshark监控，过滤器为tcp.port == 60917监听网卡lo (127.0.0.1)
compute.ly-compute1 ly-compute1:60482【可选】可在ly-compute1主机上进行Wireshark监控，过滤器为tcp.port == 60482监听网卡eth1 (10.0.0.31)
compute.ly-compute2 ly-compute2:37466需要在ly-compute2主机上进行Wireshark监控，过滤器为tcp.port == 37466监听网卡eth1 (10.0.0.32)

1. 整数消耗类的
IntFilter


CoreFilter
host有个VCPU资源，需要被VM消耗一个数值vcpus


RamFilter
host有个内存资源，需要被VM消耗一个数值memory_mb


DiskFilter
host有个硬盘资源，需要被VM消耗一个数值root_gb + ephemeral_gb + swap


NumInstancesFilter
host有个实例个数属性，看是否小于配置常数50


IoOpsFilter
host有个IO操作数属性num_io_ops，看是否小于配置常数8（builds/resizes/snaps/migrations）




2. 集合类的
SetFilter
map和item都可以看做是set，所以是set之间是否包含的问题


AvailabilityZoneFilter
host有一个availability_zone的set，看VM的需求zone是否在set里
host::set <-- VM::item


SameHostFilter
host有一个实例set，看VM的目标uuid是否在set里
host::set <-- VM::item


DifferentHostFilter
与SameHostFilter相反
!(host::set <-- VM::item)


ServerGroupAffinityFilter
VM有一个主机组set，看host的主机名是否在set里
host::item --> VM::set


ServerGroupAntiAffinityFilter
与ServerGroupAffinityFilter相反
!(host::item --> VM::set)


TypeAffinityFilter
host有一个实例类型set，set中必须只有一个元素，并且就是VM的实例类型
host::set->count == 1 && host::set <-- VM::item


ImagePropertiesFilter
host有一个所支持镜像属性set，看VM的镜像属性set是否包含在前者set里（architecture, hypervisor type, or virtual machine mode）
host::set <-- VM:set


ComputeCapabilitiesFilter
VM有一个所支持的额外需求特性map，host也有一个特性map，看VM的map是否全在host的map里
host::map <-- VM::map


3. 函数类的
FuncFilter


SimpleCIDRAffinityFilter
host的IP属性与VM的IP属性满足某个函数（同一网段）


TrustedFilter
host的name属性与VM的PCA属性满足某个函数（远程证实）


IsolatedHostsFilter
host的isolated属性与VM的isolated属性满足某个函数（同为true或者同为false）
