Messaging Performance Statistics
Messaging Performance Statistics enables you to view the performance
statistics for the service operation that flows through RabbitMQ. 
Messaging
(RabbitMQ) is a message broker
which accepts and forwards the messages to components.
On the APM Dashboard > click MESSAGING PERFORMANCE
Messaging Performance Statistics dashboard provides following information:
Global Counts

Connections |
Displays the total number of connections to rabbitmq servers. Usually product components such as control tower, logstash, agents and robots connects to the rabbitmq server. By default around 10 connections are present. Other connections are established based on number of agents and robot deployed. Additionally, if any customization is done then, count may increase according to number of connections with rabbitmq. |
Channels |
Channel is usually created to publish (to send data) or subscribe (to receive data) from rabbitmq server. |
Exchanges |
Exchanges routes messages (automation requests, various commands from control tower and so on.) based on arguments containing headers and optional values. |
Queues |
Stores messages that are used by the applications. |
Consumers |
Various applications/components that are connected to send/receive data from rabbitmq server. |
Nodes Details

Following is field description of the nodes:
Nodes details |
Description |
Name |
Displays the name of node in the cluster. |
Uptime |

Erlang processes |
RabbitMq runs on top of Erlang run-time. Erlang processes enables you to understand the required capacity in a network to provision correctly. Displays the number of erlanng processes opened by rabbitmq server. On hovering a mouse over erlanng, you can view following information: · File descriptors: It shows the number of file descriptor used by rabbitmq server. · Socket descriptors: It shows the number of sockets open by rabbitmq server. |
Memory |
