Understanding rabbitmq-diagnostics report

[Arshad Khan]

Hello All,

(Using rabbitmq 3.9.5 on CentOS7.)

I trying to understand the report generated by rabbitmq-diagnostics (or rabbitmqctl). Specifically I am having hard time correlating data values with column names as reported in the 'Listing queues' section. Here, I see these column names:

name    durable auto_delete     arguments       policy  pid     owner_pid      exclusive        exclusive_consumer_pid  exclusive_consumer_tag  messages_ready messages_unacknowledged  messages        messages_ready_ram      messages_unacknowledged_ram     messages_ram    messages_persistent     message_bytes   message_bytes_ready     message_bytes_unacknowledged    message_bytes_ram       message_bytes_persistent        head_message_timestamp  disk_reads      disk_writes    consumers        #       these   are     aliases consumer_utilisation    consumer_capacity       memory  slave_pids      synchronised_slave_pids state   type   leader   members online

One column name is weird ` consumers        #       these   are     aliases`. Is this one column or multiple columns.

Also the data values are messed up. For example,

my_queue
true
false
[]
<rabbit@rmq_server.1683056022.487.0>
false
221
0

The first four values correctly correspond to the column names but after that things are not correct. The policy, for example, is shown as `<rabbit@rmq_server.1683056022.487.0>` which does not look like the policy I have set. Anyway assuming this is some internal representation of policy, the value after it is 'false' and the column it corresponds is `pid`. This cannot be correct, right?

I'd appreciate any help in understanding the list_queue part of report. I understand my rabbitmq version is old but this is what is currently running on the customer's system.

Regards
