RabbitMQ Monitoring

Overview

Applications Manager monitors the critical components of RabbitMQ servers to detect individual queues and collect metrics which reflect the queue's performance and throughput.

The critical components of RabbitMQ servers include:

• Queued messages and message rates statistics
• Node details like socket descriptor and Erlang process utilization
• Channel statistics like message publish rates
• Exchange message rates
• In depth connection status

Creating a new RabbitMQ server monitor

Using the REST API to add a new RabbitMQ monitor:Click here

To create a RabbitMQ Server Monitor, follow the steps given below:

1. Click on New Monitor link.
2. Select RabbitMQ under the Middleware/Portal list.
3. Enter the Display Name and the name of the host where the RabbitMQ Server is running.
4. Enter the Port ID where the management plugin is configured. For default installations of RabbitMQ management plugin, the port number is 55672.
5. Enter the correct User Name and Password of RabbitMQ server.
6. You can select the Monitor Specific Parameters option to restrict discovery and monitor specific parameters in RabbitMQ monitor. This option will help to restrict Discovery of various parameters including Queues, Exchanges, Channels and Connections. If Monitor Specific Parameters option is enabled, specify the Discovery Filter Regex based on which the parameters are to be discovered and monitored. Learn more
7. Set the polling interval.
8. If you are adding a new monitor from the Central Server, select a Probe Server.
9. Select the Monitor Group from the combo box with which you want to associate RabbitMQ server (optional). You can choose multiple groups to associate your monitor.
10. Click Add Monitor(s). This identifies RabbitMQ server from the network and starts monitoring.

Monitored Parameters

RabbitMQ monitoring includes delivering proactive alarm notifications during network congestion, checking if a consumer is processing slowly or has gone down under heavy message traffic, identifying performance bottlenecks due to high socket descriptors utilization and generating historical reports.

• Availability tab shows an availability history bar graph of the RabbitMQ server. Using the drop-down list at the right-hand corner of the page, you can set the bar chart to show availability history for the past 24 hours or 30 days.
• Performance tab gives a graphical representation of the publish, delivery, acknowledged and unacknowledged rates of RabbitMQ server as well as the health history for the past 24 hours or 30 days. The colored icons at the corners of the graphs pop up a 'heat chart' for the respective metric rate.
• List view tab lists all the RabbitMQ servers monitored by Applications Manager along with their overall availability and health status. You can edit the monitor details and configure alarms from the list. You can also perform bulk admin configurations from this view.

The table below gives a detailed description of the parameters displayed in each of the following tabs:

• Overview
• Nodes
• Queues
• Exchanges
• Channels

Monitor Information	General details like name, type, health, host name, etc.
Availability history for last 6 hours	Bar graph showing the availability history of the server for the last six hours.
Performance history for last 6 hours	Chart showing the performance history of the server for the last six hours.
Queued Messages	Message vs time graph showing the ready and unacknowledged messages.
Message Rates	Message per second vs time graph showing the deliver, acknowledged and publish rates

Nodes

Parameter	Description	Mode of Monitoring
		SSH mode	Prometheus mode
Nodes
Name	The name of the node.
Socket descriptors used/available/utilization	The number of concurrently open/available/used socket descriptors for the monitor.
Erlang processes used/available/utilization	The number of concurrently open/available/used Erlang processes for the monitor.
Running	Indicates whether the node is running or not.
Node Memory and Disk Details
Name	The name of the node.
Memory Used	The amount of memory used by the monitor (in MB).
Memory Available	The amount of memory available for the monitor (in MB).
Memory Utilization	The amount of memory utilized by the monitor (in %).
Disk Free Space	The available free space on the disk (in GiB).
Disk Free Limit	The minimum free space on the disk (in MiB). Upon reaching this limit, RabbitMQ will no longer accept messages.
Usable Disk Space	The amount of usable space on the disk (in %).
Disk Free Alarm	Indicates whether the disk free limit has been reached.

Queues

Parameter	Description	Mode of Monitoring
		SSH mode	Prometheus mode
Name	The name of the message queue.
Virtual Host	The name of the Virtual Host in which the queue is created.
Exclusive	Number of messages of the exclusive consumer subscribed to this queue.
Messages Ready	Number of messages ready to be delivered to clients.
Messages Unacknowledged	Number of messages delivered to clients, but not unacknowledged yet (meaning it is in progress or has been reserved).
Total Messages	Sum of ready and unacknowledged messages (queue depth)
Incoming rate	The rate at which messages are received.
Deliver/Get rate	The rate at which messages are delivered.
Ack rate	The rate at which messages are acknowledged.

Exchanges

Parameter	Description	Mode of Monitoring
		SSH mode	Prometheus mode
Name	The RabbitMQ exchange name.
Virtual Host	The name of the Virtual Host to which the exchange belongs.
Type	The exchange type. (direct, topic, headers, or fanout)
Incoming Publish rate	The per second rating of incoming messages.
Outgoing Publish rate	The per second rating of outgoing messages.

		SSH mode	Prometheus mode
Channel	The channel through which messages are sent.
User Name	The RabbitMQ username associated with the channel.
Prefetch msgs	QoS prefetch count value for the channel.
Unacked msgs	Number of messages delivered via this channel, but not yet acknowledged.
Unconfirmed msgs	Number of published messages not yet confirmed. On channels not in confirm mode, this remains 0
Publish rate msgs/sec	The per second publishing rate of messages.
DeliverGet rate msgs/sec	The per second recieving rate of messages.
Ack rate msgs/sec	The per second acknowledgment rate of messages.
