RabbitMQ
RabbitMQ
Plugin: go.d.plugin Module: rabbitmq
Overview
This collector monitors RabbitMQ instances.
It collects data using an HTTP-based API provided by the management plugin. The following endpoints are used:
/api/overview/api/node/{node_name}/api/vhosts/api/queues(disabled by default)
This collector is supported on all platforms.
This collector supports collecting metrics from multiple instances of this integration, including remote instances.
Default Behavior
Auto-Detection
This integration doesn’t support auto-detection.
Limits
The default configuration for this integration does not impose any limits on data collection.
Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Setup
Prerequisites
Enable management plugin.
The management plugin is included in the RabbitMQ distribution, but disabled. To enable see Management Plugin documentation.
Configuration
File
The configuration file name for this integration is go.d/rabbitmq.conf.
You can edit the configuration file using the edit-config script from the
Netdata config directory.
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/rabbitmq.conf
Options
The following options can be defined globally: update_every, autodetection_retry.
| Name | Description | Default | Required |
|---|---|---|---|
| update_every | Data collection frequency. | 1 | False |
| autodetection_retry | Recheck interval in seconds. Zero means no recheck will be scheduled. | 0 | False |
| url | Server URL. | http://localhost:15672 | True |
| collect_queues_metrics | Collect stats per vhost per queues. Enabling this can introduce serious overhead on both Netdata and RabbitMQ if many queues are configured and used. | False | False |
| timeout | HTTP request timeout. | 1 | False |
| username | Username for basic HTTP authentication. | False | |
| password | Password for basic HTTP authentication. | False | |
| proxy_url | Proxy URL. | False | |
| proxy_username | Username for proxy basic HTTP authentication. | False | |
| proxy_password | Password for proxy basic HTTP authentication. | False | |
| method | HTTP request method. | GET | False |
| body | HTTP request body. | False | |
| headers | HTTP request headers. | False | |
| not_follow_redirects | Redirect handling policy. Controls whether the client follows redirects. | False | False |
| tls_skip_verify | Server certificate chain and hostname validation policy. Controls whether the client performs this check. | False | False |
| tls_ca | Certification authority that the client uses when verifying the server’s certificates. | False | |
| tls_cert | Client TLS certificate. | False | |
| tls_key | Client TLS key. | False |

Metrics
Metrics grouped by scope.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
Per RabbitMQ instance
These metrics refer to the entire monitored application.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| rabbitmq.messages_count | ready, unacknowledged | messages |
| rabbitmq.messages_rate | ack, publish, publish_in, publish_out, confirm, deliver, deliver_no_ack, get, get_no_ack, deliver_get, redeliver, return_unroutable | messages/s |
| rabbitmq.objects_count | channels, consumers, connections, queues, exchanges | messages |
| rabbitmq.connection_churn_rate | created, closed | operations/s |
| rabbitmq.channel_churn_rate | created, closed | operations/s |
| rabbitmq.queue_churn_rate | created, deleted, declared | operations/s |
| rabbitmq.file_descriptors_count | available, used | fd |
| rabbitmq.sockets_count | available, used | sockets |
| rabbitmq.erlang_processes_count | available, used | processes |
| rabbitmq.erlang_run_queue_processes_count | length | processes |
| rabbitmq.memory_usage | used | bytes |
| rabbitmq.disk_space_free_size | free | bytes |
Per vhost
These metrics refer to the virtual host.
Labels:
| Label | Description |
|---|---|
| vhost | virtual host name |
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| rabbitmq.vhost_messages_count | ready, unacknowledged | messages |
| rabbitmq.vhost_messages_rate | ack, publish, publish_in, publish_out, confirm, deliver, deliver_no_ack, get, get_no_ack, deliver_get, redeliver, return_unroutable | messages/s |
Per queue
These metrics refer to the virtual host queue.
Labels:
| Label | Description |
|---|---|
| vhost | virtual host name |
| queue | queue name |
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| rabbitmq.queue_messages_count | ready, unacknowledged, paged_out, persistent | messages |
| rabbitmq.queue_messages_rate | ack, publish, publish_in, publish_out, confirm, deliver, deliver_no_ack, get, get_no_ack, deliver_get, redeliver, return_unroutable | messages/s |
Alerts
There are no alerts configured by default for this integration.
Troubleshooting
Debug Mode
To troubleshoot issues with the rabbitmq collector, run the go.d.plugin with the debug option enabled. The output
should give you clues as to why the collector isn’t working.
-
Navigate to the
plugins.ddirectory, usually at/usr/libexec/netdata/plugins.d/. If that’s not the case on your system, opennetdata.confand look for thepluginssetting under[directories].cd /usr/libexec/netdata/plugins.d/ -
Switch to the
netdatauser.sudo -u netdata -s -
Run the
go.d.pluginto debug the collector:./go.d.plugin -d -m rabbitmq
