If your don't config exchange, this plugin didn't filter all exchanges, even no measurement created.

func gatherExchanges(r *RabbitMQ, acc telegraf.Accumulator) {

if you didn't specify exchange list, measurements rabbitmq_exchange didn't created.

didn't find out why.

[danielnelson]

What is the response of curl http://localhost:15672/api/exchanges?

[crazy-canux]

When I specify nothing for exchange, rabbitmq_exchange not created.
When I specify something, rabbitmq_exchange created.

return all exchanges.:

[{"name":"","vhost":"/","type":"direct","durable":true,"auto_delete":false,"internal":false,"arguments":{}},{"name":"amq.direct","vhost":"/","type":"direct","durable":true,"auto_delete":false,"internal":false,"arguments":{}},{"name":"amq.fanout","vhost":"/","type":"fanout","durable":true,"auto_delete":false,"internal":false,"arguments":{}},{"name":"amq.headers","vhost":"/","type":"headers","durable":true,"auto_delete":false,"internal":false,"arguments":{}},{"name":"amq.match","vhost":"/","type":"headers","durable":true,"auto_delete":false,"internal":false,"arguments":{}},{"name":"amq.rabbitmq.log","vhost":"/","type":"topic","durable":true,"auto_delete":false,"internal":true,"arguments":{}},{"name":"amq.rabbitmq.trace","vhost":"/","type":"topic","durable":true,"auto_delete":false,"internal":true,"arguments":{}},{"name":"amq.topic","vhost":"/","type":"topic","durable":true,"auto_delete":false,"internal":false,"arguments":{}},{"name":"aws_exchange","vhost":"/","type":"direct","durable":true,"auto_delete":false,"internal":false,"arguments":{}},{"message_stats":{"publish_in":258,"publish_in_details":{"rate":0.0},"publish_out":258,"publish_out_details":{"rate":0.0}},"name":"job_exchange","vhost":"/","type":"direct","durable":true,"auto_delete":false,"internal":false,"arguments":{}},{"name":"report_exchange","vhost":"/","type":"direct","durable":true,"auto_delete":false,"internal":false,"arguments":{}},{"message_stats":{"publish_in":86,"publish_in_details":{"rate":0.0},"publish_out":86,"publish_out_details":{"rate":0.0}},"name":"task_exchange","vhost":"/","type":"direct","durable":true,"auto_delete":false,"internal":false,"arguments":{}}]

[danielnelson]

Can you share your config for the the two cases: with and without exchanges set?

[crazy-canux]

Sure, this one.

#   ## A list of exchanges to gather as the rabbitmq_exchange measurement. If not
#   ## specified, metrics for all exchanges are gathered.
    exchanges = ["job_exchange", "task_exchange", "report_exchange"]

[crazy-canux]

But, when I create another influxdb and telegraf, it's works.
No idea what's happend on another stack.

[danielnelson]

Maybe it is a permissions issue?

[crazy-canux]

impossible， I got other measurements with the same url.

[Art1k]

Hey, i've got the same issue, no exchange metrics for blank.
If i try to put regex or something i get parsing error

[danielnelson]

@Art1k This option is only in the next release (1.6)

[Art1k]

@danielnelson
Thank you, got ya
Is there an ETA for 1.6?

[danielnelson]

Depends on what is found in testing but I expect it in about 2 weeks. There is an release candidate available, it would be great if you could verify everything is working as expected:

https://community.influxdata.com/t/telegraf-v1-6-0-rc2/4601

[Art1k]

@danielnelson Cool thanks, i'll verify it and update

[sspaink]

Closing because from the comments it seems this was resolved in v1.6
