Missing queues from RabbitMQ Metricbeat - elasticsearch

Question

It looks like only a fraction of the queues on my RabbitMQ cluster are making it into Elasticsearch via Metricbeat.
When I query RabbitMQ's /api/overview, I see 887 queues reported:
object_totals: {
consumers: 517,
queues: 887,
exchanges: 197,
connections: 305,
channels: 622
},
When I query RabbitMQ's /api/queues (which is what Metricbeat hits), I count 887 queues there as well.
When I get a unique count of the field rabbitmq.queue.name in Elasticsearch, I am seeing only 309 queues.
I don't see anything in the debug output that stands out to me. It's just the usual INFO level startup messages, followed by the publish information:

I think if there were a problem getting the queue, I should see an error in the logs above as per https://github.com/elastic/beats/blob/master/metricbeat/module/rabbitmq/queue/data.go#L94-L104
Here's the metricbeat.yml:
metricbeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: true
reload.period: 10s
setup.template.settings:
index.number_of_shards: 1
index.codec: best_compression
name: metricbeat
fields:
environment: development
processors:
- add_cloud_metadata: ~
output.logstash:
hosts: ["xxx"]
Here's the modules.d/rabbitmq.yml:
- module: rabbitmq
metricsets: ["node", "queue", "connection", "exchange"]
enabled: true
period: 2s
hosts: ["xxx"]
username: xxx
password: xxx

Answer 1

I solved it by upgrading Elastic Stack from 7.1.1 to 7.2.0.
